Thankfully, we don’t hear news like this very often, but these instances highlight the importance of consistent pipeline corrosion protection. Metal corrosion costs the United States around $300 billion every year, but most people rarely hear about these costs unless they manifest themselves in a disaster.

In March, a corrosion problem on a natural gas pipeline in Nothern Mexico caused a rupture and massive explosion. The causes of pipe erosion are numerous, but regardless of cause, the results can be disastrous.

The carbon-steel pipeline was 30 inches in diameter and tested to withstand minimum pressures of 60,000 pounds per square inch. Per the report filed by Energy Transfer Partners along with the Pipeline and Hazardous Materials Satefy Administration, the pipeline was being operated within its safety limits and there was no evidence of foul play, human error, or technical issues.

Pipe corrosion prevention efforts leading up to the incident didn’t ring any alarm bells, but perhaps the lengths between them did. The most recent test of pipeline integrity was an internal inspection done in 2015. Another test was done prior in 2008. Alarmingly, though, the pipeline hadn’t been hydro-tested since 1962.

Fortunately, nobody was injured by the explosion. It did wreak serious havoc on its surroundings. They reported the widest part of the rupture to be 94 inches, while the full circumference of the rupture measured 864 inches. Buried five feet underground, the explosion was powerful enough to roast a nearby highway and a house under construction. Officials estimated the explosion’s 621-foot blast radius caused about $1.4 million in damages.

All technical systems were in order. Four employees working during the incident were tested for drugs and alcohol and these tests came back negative.

In the world of pipelines, sometimes no real error is the cause of a disaster. Hence, pipe corrosion prevention efforts have to be diligently and regularly practiced. Pipelines cannot be treated as out of sight, out of mind or we end up with dangerous incidents like this. Luckily, this event — though disastrous — didn’t harm any human beings. Yet it remains a reminder that pipe corrosion prevention is of utmost importance.

Over time, it’s only natural for your pipes to wear down and corrode under the pressure of external factors. But this doesn’t mean pipe corrosion is welcome; in fact, pipeline corrosion costs the U.S. more than $9 billion each year on average. Without the proper corrosion protection system in place, you may find your pipes corrode faster than you think.

But what causes this corrosion in the first place? Here, we’ll talk about what factors in your soil can influence the health of your metal pipes and how pipe corrosion prevention can help.

Water

There is always some level of water present in your soil. Try as they might, no plumber is able to craft metal pipes that are resistant to the slow corrosion performed by water.

The primary reason water will corrode the outside of your pipes is due to its oxygen content. This causes a reaction with the metal, promoting oxygenation and later rusting of these sensitive metals. But there are many causes of pipe erosion because of water. Fast-moving water or water that changes direction quickly can wear down your pipes at a faster rate than slow-moving water. If this water is particularly hot, the corrosion happens even quicker.

You should take water pH into account as well. While we’re used to drinking neutral water, particularly acidic or basic minerals derived from the soil are common. These very high levels or very low levels can strip a pipe of its protective coating over a shorter period of time than pipes laid in more basic soils.

Soil composition

Soil is composed of a number of organic and inorganic components. While soils with a high organic content can be great for the appearance of your lawn, they might not be so good for your pipes. Healthy soils promote more plant growth and these roots can eventually make their way into the weak spots of your pipes. On the other end of the spectrum, very dry soils with little to no organic matter are actually more sensitive to sudden environmental changes. If the soil shifts suddenly, it can upset the integrity of your pipes.

Of course, the pH of the soil can also affect the life of your pipes. Talk to your plumber about the many causes of long-term pipeline integrity today for more information.

In 1990, pipeline corrosion was found to be the number one factor in pipeline failure within the Gulf of Mexico. Over ten years later, studies found that corrosion was the largest culprit in pipeline failures involving hazardous liquids and natural gas.

Pipeline failure is something no business owner wants to experience. The damage can be catastrophic and incredibly expensive. As a business owner, you want to be sure you are protected.

Keep reading to learn why corrosion is the most common cause of pipeline failure and all about pipeline corrosion prevention.

Pipelines 101

Pipelines are defined as structures transporting liquid or gas, including the pipes, valves, and all accessories (pump stations, regulator stations, compressors, etc.) attached to these components. 

Pipelines are used in many industries, including the transport of

  • oil and gas
  • fertilizer
  • compressed air
  • water
  • waste

Causes of Pipeline Failure and Corrosion

There are several factors that influence pipeline failure. These include things like poorly-executed excavation projects, natural forces, machine failure, and failure occurring in the materials and welding.

However, these causes are not the number one cause of pipeline failure, because they’re rare. What does cause pipeline failure is the everyday wear and tear on pipelines. This is most evident in pipeline corrosion, as impurities and other factors chip away at the protective coating on pipes.

As this coating wears away, it leaves the pipe open to corrosion and eventual failure. 

There are many causes of pipeline corrosion, some of which are specific to the material being transported. In the case of water pipes, here are some potential causes of external corrosion:

  • Water pH: acidic water or low pH levels harm pipeline coating and cause corrosion.
  • Chemicals and impurities: certain minerals and impurities can promote corrosion.
  • Poor installation: pipelines that were installed improperly will be more exposed to dirt, debris, and other factors that can cause corrosion.

Pipeline Corrosion Prevention

Externally, corroded pipelines may look like clusters of mineral deposits, especially around connection points on the pipeline. These deposits are thick, uneven, and bulky, and the first sign that you have a corrosion problem.

This first stage of corrosion may turn rust-colored as the problem progresses.

As with many projects and investments, prevention is key when it comes to properly maintaining pipes. Here are some ways to minimize external pipeline corrosion. 

  • Adding a layer of external protection to the pipes, such as using corrosion inhibitor solutions
  • Investing in pipe wear pads, which do not interfere with cathodic corrosion protection and help prevent pipeline failures due to friction, expansion, or contraction
  • Investing in coated pipes and connectors for future projects and repairs

Protect Your Business

As a business owner, it’s incredibly important to know the location of your pipelines and to have a plan should a failure occur.

Thankfully, pipeline corrosion and eventual pipeline failure are preventable, and there are several ways to implement pipeline corrosion prevention in your business model. For more resources on protecting your pipes, visit our blog today.

In 2018, the plumbing industry accounted for $107 billion in revenue. With money like that on the line, there’s no excuse for cutting corners on your industrial piping system’s maintenance and upkeep.

One essential that you should never skimp on is a pipe wear pad.

Not sure what a pipe wear pad is or how it can save you money? Read on for the quick-and-dirty of pipe pads.

The Battle Against Corrosion

There is a constant battle against corrosion as a plant owner or operator. From the time you install an industrial piping system to the day the building falls down, preventing corrosion on the pipes will be an uphill battle.

Causes of Corrosion

The most common cause of corrosion to your pipes is friction. Friction, caused by unavoidable movement of the pipes against their support structures, can scratch the protective coating off your pipes. This leaves an area of exposed metal on each pipe.

The exposed metal typically occurs at support points, where the pipes are being held up, held down, or otherwise secured. It’s the most common place on a pipe to see two metal pieces rubbing together.

Condensation collects at this area where the metal pieces rub together and corrodes the pipes. This corrosion rapidly wears down your pipes and costs you money in repairs.

Cures for Corrosion

There is no cure for corrosion, but there are steps that can be taken to reduce friction, protect the coating on your pipes, and prevent pipe wear.

Support Upgrades

One option to help to would be to change out the type of support structure you have on all of your pipes. A different support could reduce the amount of metal that comes in contact with the pipes, and ultimately reduce corrosion.

Changing out a full-saddle for a half-saddle would reduce the amount of metal from the support that is touching the pipe by almost half.

Is changing out every support structure in your building feasible? Not always. You have to consider the building design, pipe size, cost of replacement, etc.

A cheaper and easier way to tackle the problem of corrosion is to install pipe wear pads.

Pipe Wear Pads

Pipe wear pads are sometimes called wear pads, pipe pad or fiber reinforced polymer (FRP) pads.

They are a form of pipe liner that is installed onto the outer diameter of the pipe.

This liner is fitted onto the pipe at points where vibrations from the pipes would cause them to rub against the support structure. This liner acts as a cushion.

It is installed in between the pipe and the support structure to isolate the pipe from the support. This reduces friction on the pipe, and saves the protective coating from getting worn off.

Installing pip wear pads is cheaper and easier than renovating the building.

Need Help Winning the Battle?

Corrosion of metals costs the United State’s economy almost $300 billion per year.

You need all the help you can get to tackle to problem of corrosion in your industrial piping system. Changing out your support system is not a reasonable answer to corrosion.

However, investing in pipe wear pads can extend the life of your system, reduce maintenance and repair costs, and save you the energy of redoing the entire pipe system.

Pipe corrosion is a common problem for oil, gas, and petrochemical industries. If companies ignore the risk of internal pipe corrosion, it may become a serious problem. Corroded pipelines lead to oil spills, shutdowns, and environmental concerns. 

Inspection of pipe exteriors is easier. A visual inspection reveals potential problems. New pipeline corrosion protection systems cut exterior corrosion risks. 

How can companies reduce leaks caused by internal corrosion? Keep reading. This guide explains how to prevent pipe corrosion.

What Causes Internal Pipe Corrosion?

Internal corrosion happens when metal deteriorates. An electrochemical reaction makes the steel rust.

Left unresolved, the corroded areas lose strength. The pipe can’t continue to hold the fluid at operating pressure.

Most corrosion results from contaminants in the product flowing through the pipeline. It may be a chemical like hydrogen sulfide or carbon dioxide. Even water causes corrosion.

Cost of Pipeline Corrosion

The estimated cost of pipe corrosion in oil and gas production industries is $1.372 billion a year. Industry officials understand preventing corrosion is the best solution.

Proactive measures reduce leaks and maintenance costs. This keeps the supply flowing while meeting safety, health and environmental policies.

Internal corrosion caused 12% of incidents on hazardous liquids and gas pipelines from 2013 to 2017. That’s about 60% of all pipeline incidents due to corrosion.

Types of Internal Corrosion

Internal corrosion causes a metal loss in two common ways. General corrosion refers to an even level of corrosion over a large area of the interior surface. Localized corrosion, also known as pitting, describes isolated spots.

If not repaired, corrosion leads to pinhole leaks, a crack in the pipe, or a rupture. If the section of pipe isn’t fixed or replaced, it reduces the flow pressure in the pipeline.

Corrosion weakens the pipe. It puts the pipeline at risk for failure. A weak pipeline is susceptible to external stresses. It could break. The result is an environmental hazard and an expensive product spill.

How To Prevent Pipe Corrosion

Pipelines operate for long periods of time for critical operations. That makes corrosion prevention a priority. Here are some methods that prevent corrosion: 

  • Regular Maintenance
  • Cut Contaminants
  • Internal Pipeline Coatings
  • Corrosion Inhibitors
  • Mechanical and Chemical Cleaning

These methods extend the life and safety of a pipeline. Let’s take a closer look at regular maintenance done inside the pipe.

Pipeline Cleaning Pigs

Pipeline pigging is a mechanical device. It’s used to clean the pipe without stopping the flow of product. The pigs clean the pipe while it’s active. They’re also used to inspect pipelines.

The pig tool moves through the pipeline with the flow of the product. A foam pig uses low-density foam shaped like a bullet. It moves through the pipeline to remove small debris and impurities.

Cleaning pigs come in various sizes and densities. Some have abrasive wire mesh to remove rust and scale deposits from inside the pipe. Some cleaning methods involve pigging plus chemicals.

A regular cleaning schedule prevents corrosion and buildup from reoccurring.

Follow Government Safety Regulations

Industry pipeline operators should follow state and federal regulations. Adhere to guidelines and standards so pipes remain strong and secure. Check all potential threats to the pipeline’s integrity.

Federal and state safety regulators inspect management programs. They identify any threats, including internal corrosion. Use all the tools and follow the rules to prevent pipe corrosion.

pipe pads

Posted by & filed under Pipe Corrosion.

You spend a lot of time and money installing, upgrading, and maintaining the industrial piping system in your building. 

It’s not an easy job, but someone has to do it. 

What if it could be a little easier? What if you could save time, money and energy with one simple trick?

Keep reading to learn the easy way to maintain your pipes with the use of pipe pads. 

What Are Pipe Pads?

Anyone who maintains industrial or commercial piping systems knows that the battle against corrosion is constant. 

Friction from vibration, found typically at the point of support, can scratch the protective coating off your pipes. This leaves an area of exposed metal-on-metal. 

When condensation collects at this metal-on-metal interface, corrosion quickly causes pipe wear. This leads to high repair and replacement costs. 

Pipe pads are your cure for the friction that wears away your protective coating.  

Pipe pads also called wear pads or fiber reinforced polymer (FRP) pads, are essentially a filament-wound, fiber-reinforced liner. This liner is fitted onto the pipe. This liner acts as a cushion to isolate the pipe from the support and eliminate friction on the pipe. 

The Alternative to Using a Pipe Pad

The alternative to using a pipe wear pad would be to change out the type of support structure you are using. A different support structure may offer better corrosion and vibration control. 

For example, using a half-saddle can reduce the amount of metal at the support site by almost half. This would reduce the area where corrosion could occur.  

But changing out every support structure in your building is an expensive hassle. And it doesn’t guarantee total friction reduction. 

It also may not be viable, given your building design, pipe size, etc. Adding wear pads for piping to your existing pipe supports allows for greater control of corrosion and vibration for a fraction of the cost, time and energy.

Installation of Wear Pads for Piping

The installation of wear pads can be time-consuming and difficult if you have to weld or epoxy the pipe pad onto the pipe. 

Unlike other FRP pipe fittings, DynaGard is easy to install.

DynaGard has a unique peel and stick feature, which cuts down on installation time. These pipe pads don’t need any specialized tools or training. 

Reasons to Choose DynaGard

What sets DynaGard apart from other pipe pads starts with the adhesive. It’s a high bond adhesive that keeps the pad firmly in place even when the pipe moves due to vibration or expansion. 

DynaGard sticks not only to pipes but also to all coatings and wraps. Because of this strong adhesive, DynaGard has to be replaced less frequently than other wear pads. 

Other unique features that set DynaGard apart from the competition include: 

  • Resistance to condensation;
  • Resistance to most chemicals and acids;
  • Resistance to degradation by ultraviolet light;
  • No interference with the CP system’s protection against corrosion; and 
  • Cathodic disbondment will not occur on the pipe pad.

These are serious advantages. 

Easy Choice to Reduce Corrosion

Corrosion prevention doesn’t have to be an uphill battle. You can maintain your industrial system more easily with the introduction of pipe pads. 

DynaGard reduces costs and energy. It’s an easy choice.

Metal on metal corrosion on your pipe saddles proves to be a serious issue with many industrial pipes.

This issue is commonly found in offshore oil and gas facilities in areas like the Gulf of Mexico. Corrosion begins when the metal is exposed to the elements, like oxygen and water, and breaks down the metal.

Pipe saddles and pads are considered to be hot spots for corrosion due to the friction caused by metal on metal rubbing against each other.

Not to worry! Here are some tips on pipeline corrosion protection due to metal on metal friction in the winter years.

Ensure Your Metal is Properly Coated

Coating your pipes in the areas around the saddles and pads with a sealant will help mitigate corrosion for a period of time.

You can use pipe coatings, such as paint on the topside of piping to protect the metal against corrosion, specifically atmospheric corrosion that you may find in mater based industrial stations.

Be aware, however, that you must perform regular maintenance on your pipes, specifically near the saddle clamps area. 

Use Sealants

To help mitigate the amount of metal on metal pipeline corrosion occurring, you may want to take advantage of using a sealant.

Sealants help prevent moisture ingress in the crevices of the saddles and pads. These sealants include silicone, epoxy and caulks. Explore this option with caution.

The sealant and steel surface may make a corrosion problem worse and form additional crevice in the bonding process.

Reevaluate the Support Being Used

There are loads of options for pipe support that may prove to be a better option than what you are currently using.

Taking advantage of an alternate solution, such as a half-saddle and cradle, can help mitigate the issue of corrosion. You can maintain the pipe more easily as well as half the amount of metal rubbing against each other.

You may also want to consider using a wear pad that reduces the metal on metal friction that causes corrosion. These pads are easy to install, and helps isolate the pipe from its support.

Some require additional welding or gluing, however, DynaGuard sells and manufactures pipe wear pads that are easy to install and offer protection to your pipes against metal on metal corrosion.

Next Steps: Which Pipeline Corrosion Protection Works Best for You?

While more pipes and their paired saddles and pads are made in stock, every corrosion problem is different.

This depends on your industry and the environment the pipes are being used in. Explore the types of pipe you have and possible roadblocks to using a specific metal on metal pipeline corrosion protection.

Pipelines run everywhere at your business-through the walls, floors, and even underground. If a pipe corrodes or bursts, that could cause major problems and you may even need to close shop while everything gets fixed.

You do not want that to happen!

There are many kinds of pipes, and many of the best options have a chance of corroding. Corrosion can be caused by many things. If you want to prevent the problem, you’ll have to plan accordingly.

In this article, we’ll discuss pipe corrosion prevention so you never have to worry about more major problems.

1. Use the Right Materials

By using the right materials on your pipes, you can drastically reduce the chances of pipeline corrosion. Steel, concrete, and copper are commonly used substances but are a bit more likely to corrode than stainless steel, plastic, or composite materials that are made to last.

Of course, the material you use depends on the application. Sometimes you will need to use a specific material, but if there are multiple options for a pipe, it may be wise to use something that is less likely to corrode.

2. Protect with Proper Linings

One of the best ways to protect from corrosion is to have a protective layer on the outside. This is actually a simple process that is done before installing pipes.

Typically it comes in the form of a peel and stick pad. You just peel off the backing and apply a pad to the surface of the pipelines.

The point of this is to reduce metal on metal, which can lead to corrosion. However, it has other protective benefits as well. These pads are UV resistant, meaning they will help the pipes last longer and they resist moisture, which can also prolong the life of the pipes.

3. Hide Your Seams

It is vital that you weld, solder, or seal all the pipe’s seams in some way.

You need to make sure everything is smooth so no shards of pipe can become a breeding ground for corrosion. Hiding the seams properly also ensures that nothing can get in that could cause potential problems.

4. Cathodic Protection

Cathodic protection, or CP for short, is a process that uses electricity to control the corrosion of pipeline materials.

In simple terms, you use a direct electrical current that is attached to your metal piping but uses a sacrificial material that will corrode instead. It sounds complicated but is actually a simple process that is used all around the world to protect pipelines.

What if Pipe Corrosion Prevention Doesn’t Help?

By taking the proper steps, you can prevent a lot of problems. Unfortunately, if you are using steel or copper piping, then eventually there will be some corrosion. At this point, the pipes will need to be fixed or replaced.

If your pipes are past the point of preventing problems, then don’t waste time trying to fix them yourself and potentially make it worse.

Corrosion occurs naturally when metal is exposed to air and the environment it’s in. And it happens over time, so you may not always notice when it’s happening. But left untreated, corrosion will impact the strength and aesthetic appeal of your metal.

So what are the easiest and most effective ways to prevent pipeline corrosion? How do you protect your investment?

It may be easier than you think. There are a few simple ideas that will ensure you can work smarter, not harder, both now and in the future. Let’s look at 3 tips!

1. Advanced Cleaning

When was the last time you cleaned the inner portions of the pipe? If you’re looking for tips on how to prevent corrosion, this is probably the first place you should look.

An advanced cleaning program means you turn to the inside of the pipe, using very non-aggressive pipeline pigs that give out low-density foam. This will help to remove contaminants and other build-up that can decrease pipeline corrosion.

If you get “under the hood” and realize there are very thick deposits of buildup, you will need a smaller pig for the job. The key is to maintain your pipes by doing this every so often, so that corrosion on the inside doesn’t have a chance to ruin your investment.

2. Best Practices

There are plenty of good reasons to fight pipeline corrosion. How else can corrosion be prevented? One other way is to look at how you’re installing the pipes to begin with. For example:

Keeping the area around the metal dry, and using drying agents to protect your pipes from water.

Making sure the piping has a layer of backfill (limestone is a good material) if it’s underground.

And finally, making sure any electrical components are cleaned regularly. This “checklist” of sorts will ensure that you have to do less maintenance cleaning on your pipes and that they still stay free of corrosion.

3. What’s On The Surface?

Corrosion is more likely to happen on the outside of the pipe than on the inside. While the most common type of coating is an epoxy coating, ask yourself what type of pipes you’re using to begin with.

Are you picking composite-based, corrosion controlled products? Doing the research before you purchase can help you find a cost-effective piping solution that will still hold up and prove worth the investment. When it comes to ways to prevent corrosion, start with the raw materials.

Prevent Pipeline Corrosion- Wrap-Up

While corrosion is a natural process, the ways to prevent pipeline corrosion are well known and pretty simple. Make sure to clean the inside and outside of your pipes, and maintain a checklist of “best practices” that make maintenance easy when the time comes.

Are you a plant owner or operator concerned about metal on metal corrosion?

According to the American Galvanizer’s Association, the estimated cost of corrosion is 3% of the United States annual GDP. In 2016, the U.S. GDP was approximately $18.57 trillion!

This surprising statistic reflects the potentially expensive costs that plant owners and other employees face each year. Chemicals are only one cause of corroded metal. Metal on metal corrosion can also cause significant issues for your plant. These can include unwanted downtime and replacement costs.

Read on to learn more about how to protect your pipes from metal on metal corrosion!

The Dangers of Friction

Friction can be the worst enemy for your pipes. That is because friction causes metal corrosion as your pipes rub together.

This can become more of a danger for your pipes as they expand and/or contract. The narrowing and enlarging can cause your pipes to push against each other.

Besides causing corrosion, metal on metal contact creates tension on your pipes that weakens them too. Over time, it can cause your pipes to corrode or break. That is because the pipes are being strained for an extended period of time.

This can result in extended downtime at your plant and may bring operations to a sand still until the damaged pipes are replaced.

These damaged pipes can also become a safety risk for your employees because of the risk of leaking over long periods of time.

You need your system to be reliable and operating efficiently so that your plant runs smoothly.

Protection From Corrosion

One of the ways to protect your plant from corroded metal is to plan ahead.

This means you should consider how your pipes will expand and contract long before they are put together. By recognizing these potential problem areas, you can prepare your pipes to avoid issues later.

But how can you protect the pipes at your plant?

DynaGard is a protective pad applied to a pipe to protect it and prevent corrosion caused by metal to metal contact. These covers have a “peel and stick” feature which make them easy to install.

They are also UV resistant which helps them to last longer even in harsh weather conditions. Besides cutting down on contact, these wear pads resist condensation, moisture, and water.

These features make DynaGard a key component in defending against unwanted corrosion at your plant!

Wrapping Up: Preventing Corrosion Caused By Metal

Metal on metal corrosion can cost your company a lot of time and money.

For example, corroded pipes may cause unwanted downtime for your plant. This can put your operations on hold until they are replaced. It can also create additional costs while you replace other pipes before they become corroded.

Are you concerned about the corrosion of pipes at your business?

According to the American Galvanizer’s Association, the cost of pipeline corrosion in the United States is approximately $9 billion annually.

These costs can have a significant impact on your company’s bottom line. But the good news is that you can be in better control of the corrosion of your pipes by being proactive.

It also helps to understand why corrosion takes place and what you can do to stop it.

Read on to learn the main causes of pipe corrosion!

Abnormal pH Levels

The pH level of the liquid flowing through your pipes can have a major impact on its lifespan.

The pH of water, for example, is a measurement of the acidity of that liquid and ranges from 0 to 14. It’s important that the pH level of the liquids flowing through your pipes is monitored by your employees.

It’s best that the pH range falls between 7.0 and 8.4. Any level lower than 7.0 or higher than 8.4 can cause corrosion to your pipes over time.

Poor Soldering of Pipes

Preventing steel pipe corrosion begins from the time those pipes are installed on your system.

You should ensure your company is using someone that is highly trained to solder pipes correctly. When someone solders two pipes together, they are using fire to melt connect two separate pieces and make them one.

While this may sound like an easy process, it’s crucial that pipes are soldered together properly. Otherwise, your business runs the risk that a pipe will have higher amounts of acid in them.

This will make your pipes more susceptible to corrosion and can create problems with flow.

High Flow Rate

Piping corrosion can also be caused by prolonged exposure to the velocity of flowing water that is too high.

Your employees must be careful not to send water shooting through pipes at a high flow rate. That’s because it can cause the pipes to wear down and become more susceptible to corrosion.

By being sure water flows into a pipe at a safe speed, your business is helping to guard against a corroded pipe.

Using Too Much Chlorine

Your business should pay attention to the amount of chlorine or other disinfectants that you are adding to liquids that go through the pipes.

Chlorine is often used by cities and private businesses to help clean up the water supply. Although chlorine can be helpful when used this way, high quantities of it can create issues for your pipes.

This is because chlorine compromises the structure of the metallic materials in your pipes. When these components are weakened, it makes them more prone to starting to corrode prematurely.

Wrapping Up: Prevent Pipe Corrosion

Preventing pipe corrosion can help save your business time and money in the long run.

You can do this by taking an active role in monitoring your pipes or installing a system to protect them. It can also help to be careful to avoid participating in activities that can make your pipes begin to corrode.

Dynagard is a pipeline corrosion protection system built to resist corrosion through its unique adhesive design. Contact us today to learn more about how our system can help protect your pipes!

Pipelines are still the safest and most effective way to carry resources such as gas and oil, among others.

While this is the case, that doesn’t mean that they don’t fall victim to ruptures and failures at times.

Unfortunately, there is no such thing as a minor problem when it comes to pipelines. In fact, these problems cost the United States millions of dollars each year.

But, one of the biggest problems they face over time is corrosion.

Read this article to find out what happens to pipelines when they corrode.

Damage to the Interior of the Pipeline

When it comes to pipeline corrosion, the contents they carry isn’t the real problem. These pipelines can carry a variety of materials and substances without corroding. Some of these include:

  • Crude oil
  • Gas
  • Biofuels

The main issue is the trace amounts of sediment and water within the materials that these pipelines are carrying.

Because the density of these substances is different, they separate. Over time, the moisture can start corroding the steel interior of the pipeline. This causes ruptures and pipeline failures.

Warmth Can thin the Interior Walls

It’s not only liquids that can cause wear and tear to the interior of a pipeline. Warmth also plays an important role.

The oil in pipelines flows better if hot. This means that these pipelines come with insulation to keep oil and other contents at a high temperature.

While the warmth is great for the oil, it thins the lining of the walls over the years. This thinning makes the steel more likely to corrode.

The Exterior Is as Important as the Interior

When it comes to pipeline corrosion, you also have to think about the exterior. The outside of a pipeline has to face rain, snow, heat, and all other extreme weather conditions mother nature throws at it.

Pipelines have protective coatings. But, some of these systems are decades old. And, keeping track and maintaining all of them requires manpower and a high level of expertise.

When Pipelines Corrode, Ruptures and Breakages Occur

Unfortunately, when it comes to pipelines, it’s not a matter of “will it happen”. It’s a matter of “when will it happen”.

No matter how well you look after your pipelines, they will fall victim to corrosion at some point in time.

When they do, they will rupture, break, and fail to do the job you intend them to. And, at over 6.3% GDP, corrosion is one of the largest expenses in the US.

But, there are ways you can make your pipelines last longer…

Preventative Measures From DynaGard

If you want to protect your pipelines from corrosion for as long as possible, you need to take the right preventative measures.

Pipelines corrode when they don’t have the right protection and maintenance. With this in mind, check out our products today.

Corrosion is the deterioration of metals and other materials through chemical interactions with its surrounding environment. If you own a factory or any other place of business with large amounts of pipelines or other metalworks, corrosion is enemy #1. Corrosion is a terribly annoying byproduct of metal pipelines. A recent study found that the global cost of corrosion to float somewhere around $2.5 trillion, which makes pipeline corrosion protection methods critical. 

That’s nearly 3.4% of our planet’s global GDPIf you own a factory or plant that houses pipelines and other metalworks, you probably already know what a cursed affliction corrosion can be. But if you’re trying to make your profit margins as wide as possible, you need to try your best to win in this battle against mother nature.

In this brief guide, we’ll discuss pipeline corrosion protection and why it’s important.

What Is Pipeline Corrosion?

Pipeline corrosion functions like any other form of corrosion. But pipes are often exposed to open air or buried underground. In these outdoor environments, they are especially susceptible to corrosion.

There are several different kinds of corrosion. And they each need to be dealt with in potentially different ways.

General Corrosion

This type of corrosion occurs due to simple exposure to the elements like wind, rain, condensation, or dust. Most commonly, this sort of corrosion comes in the form of rust and affects the entire structure, or segment, of a pipeline.

The good news is that this form of corrosion happens slowly and can be easily spotted and prevented.

Localized Corrosion

As the name suggests, this form of corrosion happens on a smaller scale but can be more disastrous as it’s tougher to spot. Localized corrosion occurs in three forms: pitting, crevice corrosion, and filiform corrosion.

Galvanic Corrosion

This type of corrosion occurs when two different metals are placed next together in certain underwater environments like saltwater. In this electrolyte-filled environment, one metal’s molecules are attracted to the other. As a result, one of the two metals corrodes at an accelerated rate.

Cathodic Corrosion

Cathodic methods of corrosion protection are by far the most complicated, but it’s very effective. Cathodic protection works by creating an electrical current around the pipe using anodes and cathodes. Simply put, this system repels corrosive molecules away from the pipe.

In a sacrificial cathodic protection system, the cathodes begin to corrode instead of the more important metal pipes.

This method protects against galvanic corrosion. Galvanic corrosion happens when two metals are placed closely together in a corrosive environment – i.e. salty seawater or wet soil.

Why It’s Important to Protect Your Pipelines

Corrosion, if not dealt with, can absolutely destroy the infrastructure of a factory or any other business. It can cause bridges to collapse, oil pipelines to bust open, or bathroom plumbing to leak. It’s estimated that corrosion costs businesses 2.5 trillion dollars globally. Corrosion is no joke, and if you want to run your business effectively, you need to know how to guard against it.

There are a few different ways to protect against corrosion. The two most popular are cathodic protection, and selecting corrosion-resistant materials to protect your pipelines. Cathode protection involves placing cathodes along your pipelines that repel harmful molecules and ions from your pipes. The alternative method of corrosion protection involves simply placing corrosion-resistant materials – like rubber – over your pipelines.

This physical guard will protect your precious metalworks from environmental forces. These forces, like rain, condensation, and debris that can damage the integrity of your pipes over time. If you’d like to learn more about how to prevent pipeline corrosion, click here.

You can also select metals and other materials that are less susceptible to corrosion when creating your pipelines. No metal is truly immune to corrosion. What once came from the ground will have to return in death, but some are better than others. Materials such as stainless steels, plastics, and special alloys can greatly extend the life cycle of a pipeline. Nickel, steel, or titanium alloys are particularly good at preventing corrosion. This is especially true when coupled with a different protection method like pipe saddles.

It’s also important to monitor the surface of the materials once you’ve put them to use. Cracks, chips, and fissures from general wear-and-tear in the pipeline can rapidly increase the rate of corrosion.

Pipeline Corrosion Protection Methods

Corrosion is a terribly annoying byproduct of metal pipelines. A recent study found that the global cost of corrosion to float somewhere around $2.5 trillion, which makes pipeline corrosion protection methods critical.

That’s nearly 3.4% of our planet’s global GDP.

If you own a factory or plant that houses pipelines and other metalworks, you probably already know what a cursed affliction corrosion can be. But if you’re trying to make your profit margins as wide as possible, you need to try your best to win in this battle against mother nature.

Below, we’ll detail 3 pipeline corrosion protection methods you can use to protect your hardware.

1. Cathodic Protection

Cathodic methods of corrosion protection are by far the most complicated, but it’s very effective. Cathodic protection works by creating an electrical current around the pipe using anodes and cathodes. Simply put, this system repels corrosive molecules away from the pipe.

In a sacrificial cathodic protection system, the cathodes begin to corrode instead of the more important metal pipes.

This method protects against galvanic corrosion. Galvanic corrosion happens when two metals are placed closely together in a corrosive environment – i.e. salty seawater or wet soil.

2. Metal Selection

In addition to cathodic protection, you can also select metals and other materials that are less susceptible to corrosion when creating your pipelines. No metal is truly immune to corrosion. What once came from the ground will have to return in death, but some are better than others.

Materials such as stainless steels, plastics, and special alloys can greatly extend the life cycle of a pipeline. Nickel, stell, or titanium alloys are particularly good at preventing corrosion. This is especially true when coupled with a different protection method like cathodic protection.

It’s also important to monitor the surface of the materials once you’ve put them to use. Cracks, chips, and fissures from general wear-and-tear in the pipeline can rapidly increase the rate of corrosion.

3. Environmental Modification

Since it takes two to tango when it comes to corrosion, you can also try to change the other end of the equation: the environment itself.

Corrosion occurs when the metals of your pipeline come into contact with the corrosive liquids and gasses in its environment. So you can also reduce corrosion by trying to get rid of or reduce the corrosive elements in your environment.

You can do this simply by limiting the metal’s contact with rain and other water by shielding it with some form of insulation, thus changing its environment.

You can also use different methods to reduce the amount of sulfur, oxygen, phosphorous, or chlorine in the soil or water the pipe is submerged in.

Haven’t taken the necessary steps to secure the safety of your pipes? Then it’s a good thing you’re here.

Corrosion is a natural occurrence, but it’s not one that you want to happen at your business or your home. Protecting your pipes should be of utmost importance.

There are two safe cathodic protection systems that are proven to extend the life of your pipes. Read on to find out more – and to learn which system is right for you.

Galvanic Cathodic Protection System

There are two types of cathodic protection systems: the galvanic protection system and the impressed current protection system.

The galvanic protection system works when sacrificial anodes are fixed to the piping during the manufacturing phase. This requires special wiring for an inspection station to be installed near the surface of the ground.

Galvanic systems have a limited lifespan that depends on the life of the sacrificial anodes, which will continue to degrade as they protect the piping. Once the sacrificial anodes fail, the pipes will start to corrode.

This form of protection is the more common of the two since it’s much easier to set up and maintain. But it doesn’t hold up as well as the impressed current system.

Impressed Current Cathodic Protection System

The impressed current protection system takes a different (and perhaps more complex) route.

The impressed current system has a rectifier that allows it to convert an alternating current to a direct current to slow the formation of rust.

In other words, it uses an external power supply to drive continuous current through the pipes, minimizing the amount of corrosion.

Because of this, the impressed current protection system usually provides a much longer lifespan than the sacrificial anodes of the galvanic protection system.

If needed, the current can also be modified to be stronger or weaker, and the greater amount of control does drive people to choose this option over the galvanic system.

That being said, the impressed current system is considerably more expensive than the galvanic system, and it’s much more permanent – meaning once it’s installed, there’s really no going back.

Make sure to think hard before you go for this option.

So What’s the Best Choice?

Both the galvanic system and the impressed current system do the job (to varying degrees of power and longevity) so the best choice is really based on your personal preference.

Most companies tend to choose the galvanic system because it’s easy to buy and install the necessary parts. Plus, replacement parts are easy to come by, and its a cinch to switch them out.

The impressed current system makes sure that the job is done right for a much longer period of time, but replacing the parts will not be an enjoyable task.

Both systems are safe for the environment, so it all comes down to your needs – and your wallet.

corrosion of pipelines

Posted by & filed under Pipe Corrosion.

America transports goods and other forms of material through 2.4 million miles of pipelines.

Crude oil, natural gases, sewer, and most importantly, water travels through these pipelines, which is why the need to understand the environmental factors that cause corrosion of pipelines is important.

Corrosion of pipelines is the leading cause of tank and pipeline failures. The United States spends $7 billion per year to monitor, replace, and maintain pipelines.

Billions can be saved if more knowledge regarding the factors that cause corrosion of pipelines was made more readily available.

Here are 4 environmental factors that can speed up the corrosion of pipelines.

Soil Resistivity and Corrosion of Pipelines

Soil Resistivity is an environmental factor that has to do with the amount of soil that resists the circulation of electricity through it.

The electric current that’s determined by soil resistivity promotes pipeline corrosion.

In a 12-month study on the relationship between soil resistivity and corrosion, the Journal of Corrosion Science and Engineering concluded that soil resistivity not only affects metals–of which pipelines are made of–but serves as an early indicator for the growth rate of corrosion.

Humidity

Humidity is a form of dew point corrosion that causes environmental corrosion in pipelines.

Dew point corrosion has to do with the damage that arises when the air rises to a certain temperature and the rate of its evaporation and condensation are at the same pressure.

Corrosion in steel pipelines happens in places where the humidity is very high. In Florida alone–which is a tropical state– there are over 31,177 miles of pipelines, 531 of which carry hazardous liquids.

Tropical states carry humid temperatures year round, a dangerous environment for pipelines. Corrosion is imminent.

Saltwater

Saltwater is another environmental factor that causes pipelines to corrode.

Steel pipelines that are exposed to saltier bodies of water like sea water corrode much faster than those near fresh water.

Salty water must be considered when making an attempt to prevent or manage pipeline corrosion.

Sulfur Dioxide

Environmental gases affect the rate of corrosion of pipelines as well. Sulfur Dioxide is one of them.

Sulfur Dioxide, usually found on the back label of most dried, packaged fruits, is a loud-smelling chemical compound.

Though harmless when it’s coated on a batch of apricots, sulfur dioxide turns to sulfuric acid when it’s combined with water and air.

Sulfuric acid is corrosive to steel.

In Summary

Miles of the American underground is inhabited by pipelines, underlying all fifty states.

Almost 200,000 of them transport hazardous liquids, while more than 300,000 haul different gases. These liquids and materials pass directly under our homes and businesses.

The United States could save billions of dollars if environmental factors were a consistent focus. These environmental factors–soil resistivity, humidity, saltwater, and sulfur dioxide–corrode pipelines, destroying the life and health of them over time.

Protecting pipelines against environmental factors that disrupt the safety of transporting hazardous materials is imperative. There are benefits to pipeline protection.

The influential National Association of Civil Engineers (NACE) Cost of Corrosion study estimated a $276 billion in direct costs annually associated with metal corrosion in 2002. In the production and manufacturing sector alone, this is a cost of $17.6 billion every year.

Corrosion is a natural occurrence and the costs associated cannot be eliminated entirely. The NACE study notes that 25%-30% of annual corrosion costs can be saved by using optimum corrosion management practices.

To prevent and control corrosion, consider the specific material to protect. What product is transported or processed? Are there environmental concerns such as saltwater or soil to consider?

Need to figure out the correct corrosion inhibitors for your pipeline? Read on to learn more.

Don’t Let Corrosion Begin

Corrosion is the primary cause of failure of pipelines and tanks. Up to 80% or $4.5 billion of the annual cost to maintain, monitor and replace these assets is due to corrosion. Corrosion inhibitors are part of the annual maintenance of your pipeline, and while costly, the alternative is much more expensive.

Selecting the correct materials for your pipeline is the first step. Take into account the material to be transported, the distance and the environment.

Corrosion requires two dissimilar metals and a current-conducting medium between the two. Preventing contact between the metals and the electrolyte medium is the goal of any inhibitor.

Four Types of Corrosion Inhibitors

A corrosion inhibitor is a material that attaches to a metal surface, providing a protective barrier against a corrosive reaction developing.

Types of corrosion inhibitors:

Anodic inhibitors react with oxygen to form a thin film on the surface of the metal. They reduce the corrosion potential of the material by oxidizing a surface layer that is less reactive to corrosive elements.

Cathodic inhibitors slow the cathodic reaction itself or limit the diffusion of reductive elements such as hydrogen or oxygen to the metal surface. Examples are cathodic poisons such as arsenic and selenium ions which slow the reaction or oxygen scavengers such as sulfite ions which limit the diffusion of oxygen.

Mixed inhibitors are compounds that form a film or precipitate to reduce both the cathodic and anodic reactions. Sodium silicate and phosphates used in domestic water softener salts to prevent rust water are examples.

Volatile corrosion inhibitors are compounds delivered to the site of corrosion in a closed environment. They form a protective film only a few molecules thick. For example, in boilers, volatile compounds such as morpholine or hydrazine, are transported with steam to prevent corrosion in condenser tubes.

In shipping, wrapping metals in volatile corrosion inhibitor-coated paper is a common short-term protection against corrosion during transit. The chemicals in the paper continuously vaporize and fill the airtight package to protect against moisture and humidity.

Engineers Evaluation

Corrosion protection is a necessary part of asset maintenance for pipelines and tanks. Professionals develop specific protection strategies using some or all of these types of inhibitors as appropriate to their environment.

pipeline corrosion protection methods

Posted by & filed under Pipe Corrosion.

What do you do about your pipes? Most homeowners install pipes and forget about them.

When they experience damages such as leaks, they just patch up their pipes or install new ones. But practicing pipe safety will save you money and time in the long-term.

Pipe corrosion is one of the worst problems that can occur with metal pipes. Corrosion eats away at the surface of your pipes, causing leaks. They often go undetected, and you don’t notice corrosion until it’s too late.

Corrosion prevention sounds difficult. But once you get in the habit, it becomes fairly simple. Use these 3 pipeline corrosion protection methods and prevent pipe damage.

1. Apply a Primer

Applying a primer or finished coating is one of the easiest pipeline corrosion protection methods. Primers act as a barrier between the steel of the pipes and the corroding elements. Primers also prevent moisture from reaching the pipes.

When there’s a coating on your pipe, it takes longer for water and oxygen to diffuse. This slows the rate of diffusion to the metal of the pipe.

Depending on the primer you use, the primer can contain anti-corrosive properties. This helps develop a high electrical resistance and absorbs moisture. Primers protect both pipe surfaces and the underlying area of the pipes.

2. Regular Cleaning

When you perform spring cleaning, don’t forget your pipes. The key to pipeline corrosion prevention is regular cleaning. Cleaning prevents corrosion; in case corrosion does occur, clean pipes minimize the corrosive effects.

You should always use suitable chemicals to thoroughly clean your pipes.

These should be applied to the inside and outside of your pipes. The moisture first targets the outside of your pipes, but debris and contaminants stick to the inside of your pipes.

To effectively clean your pipes, use chemicals and wash off debris with a brush.

For thicker deposits such as wax, use a blade.

3. Choose Specific Materials

The best way to prolong pipeline life is by choosing appropriate materials. Metal is the most common chosen pipeline material, but it can be an easy victim of corrosion.

When installing your pipeline, choose corrosion-resistant materials. These include stainless steel, plastic, and other special alloys. If you prefer to have a metal or steel pipeline, consider adding one of these materials to your pipes.

However, keep in mind these materials largely depend on the environment of the pipes. Metal is often chosen because it can survive in several environments.

Always ask your pipe installer for advice.

Use These Pipeline Corrosion Protection Methods

If you don’t monitor your pipeline, your pipes will eventually deteriorate. One of the most common pipeline problems is corrosion. Corrosion weakens the integrity of your pipes, resulting in issues such as leaks.

When this occurs, you need to reinstall your pipe system.

Simple monitoring prevents spending lots of money on a new pipe system. Common pipe protective methods include consistently cleaning your pipes and using a primer or corrosion-resistant material.

pipeline maintenance

If you’re a plant owner or operator, there’s nothing more concerning than the C word. C, of course, stands for corrosion.

But pipes that don’t corrode are non-existent. Okay, plastic pipes don’t corrode. But they degrade, which means they’re also not perfect.

The good news though is there’s a way to avoid pipeline failure. And it has everything to do with pipeline maintenance and protection.

What is Pipeline Maintenance?

As you can gather from its name, pipeline maintenance means maintaining the integrity of a pipeline and all of its components. This is not a do-it-once-and-forget-about-it kind of thing.

You want to be as thorough as possible with maintaining your pipes if you want to keep them safe for life. This involves careful inspection, leak detection, and making sure the inside of the pipeline is clean as can be.

How to Protect Your Pipes

Since corrosion is the number one enemy of a pipeline, it makes sense to invest in corrosion protection. As we’ve said before, there are five ways to do this.

First is regular cleaning, which usually involves pigging and chemicals. Clearing the area around the line is also part of this process. Remember that any new vegetation growth could impede the proper functioning of the pipe.

Other corrosion protection methods are cathodic protection, use of corrosion inhibitors, as well as coating and linings, and abrasive blasting.

The Cost of Not Doing Maintenance for Your Pipes

$2.2 trillion. That’s the annual global cost of corrosion according to the World Corrosion Organization. But it’s not just about money. Corroded structures including pipelines can and do cause injury and death.

Corroded water pipes, for example, don’t just cause premature failure of plumbing systems and fixtures. Anyone who ingests corrosive water is in danger of exposure to heavy metals such as lead.

As you may already know, long-term exposure to lead has been linked to diseases including cancer, high blood pressure, stroke, seizures, and behavioral disorders (in children).

As for corroded oil and gas pipelines, there are other dangers to consider aside from hazardous materials leaking into the environment. Oil and gas are flammable, which means these lines are very much susceptible to explosions when exposed to heat or flame.

Plus, there’s the fact that replacing aging pipelines isn’t always practical. According to the National Association of Corrosion Engineers (NACE), oil and gas companies spend more than $7 billion annually to repair or replace corroded pipes. That’s a considerable amount compared to investing in fast, easy, and cost-effective pipe corrosion protection.

Prioritize Pipeline Maintenance and Protection

Now that you know the importance of maintaining and protecting the integrity of your pipes, it’s time to think about your options.

If you’re considering the most cost-effective solution, you can’t go wrong with DynaGard pipe saddles. Our products are designed to quickly eliminate the risk of pipe corrosion through prevention of moisture penetration and metal on metal contact.

corrosion prevention

Posted by & filed under Pipe Corrosion.

How can you implement a corrosion prevention plan for your pipelines? It’s not easy since corrosion is a part of nature’s process to break down materials.

It’s also the main cause of pipeline and storage tank leaks and breakdowns. These breakdowns cost up to $17 billion, according to NACE International.

Are you looking for ways to protect your pipelines from corrosion and economic catastrophe?

Read on for ways that proper corrosion prevention can save your pipelines.

What Causes Corrosion?

To understand how to best protect against corrosion, we have to first look at the underlying causes of corrosion.

Most pipelines are made from galvanized steel and coated with protective paint. Looking at steel at the cellular level, there are 4 components: an anode, cathode, electrolyte and a connected electronic path. These components make a galvanized cell.

Corrosion happens when the protective paint is compromised and the steel is exposed. These four components come into contact with soil or water. When exposed to the elements, the anodes and cathodes carry an opposite polar charge, connected by the electronic current.

The anodes then break down at a fast pace, causing corrosion. The corrosion then spreads throughout the pipeline, causing a tremendous amount of damage.

One of the main areas where corrosion occurs is around pipe supports. Pipe supports have a tendency to rub against the pipes, which can cause the protective paint to wear down. Water can also be trapped between the pipe and support. This combination can initiate the process of corrosion.

Once corrosion begins under pipe supports, it’s virtually impossible to inspect and maintain.

Wear Pads for Corrosion Prevention

There are multiple ways to protect your pipelines from corrosion.

Most pipelines have some sort of protective coating. The thing to understand about corrosion is that if one small area of the coating is cracked, that small area becomes vulnerable to the elements and corrosion.

That small area can make your entire pipeline vulnerable to corrosion.

By using wear pads in conjunction with pipe saddles, you can prevent metal to metal contact and prevent moisture from building up around the joint.

The thing is that not any wear pad is sure to protect pipes from corrosion.

Wear pads that separate the pipes from the support beam can prevent the direct contact. That would prevent the protective paint from breaking down.

The other critical piece is to have a wear pad that prevents moisture build up. Dynagard’s wear pads have a high-bond strength adhesive liner to prevent moisture from penetrating the support area.

Leave Corrosion Prevention to Professionals

Are you still concerned about the potential damage caused by corrosion? It’s easy to understand why, given how much economic and infrastructure damage can happen as a result.

Corrosion prevention requires a professional and experienced firm to diagnose and resolve potential hazards.

At DynaGard, we have over 15 years of experience working with the largest oil companies to protect their pipelines from corrosion, saving them time and money.

Pipelines are critical for infrastructure in the modern world. There are over 2.4 million miles of pipeline in the United States alone. Unfortunately, all these pipelines are susceptible to corrosion.

Pipeline corrosion protection is very important because corrosion can make water unfit to drink. It can also expose the environment to harmful materials.

Are you looking for some ways to ensure your pipeline stay free or corrosion? Maybe you already have a problem and need help on what to do?

Don’t worry, keep on reading for five easy methods to handle corrosion in any pipeline.

1. Protection & Cleaning

When thinking about corrosion protection methods, cleaning and protection should be at the top of the list. In combination with a Dynaguard corrosion protection system, regular cleaning will help to prevent corrosion. This can help you avoid having to deal with getting rid of corrosion down the road.

Have your pipelines cleaned regularly. This usually involves pigging and chemicals. Depending on the severity of your corrosion problem, different tools and materials may be used.

Another part of pipeline upkeep is clearing the area around the line. Pipelines will only function correctly if their path is not interrupted.

During the planning phase, be sure to remove all nearby tree roots. Monitor the area afterward for any new vegetation growth that could affect the pipe. Keeping the area clear will also make any needed repairs easier.

2. Cathodic Protection

This method of dealing with corrosion uses an electrical current. This controls the corrosion from becoming worse by neutralizing it.

Cathodic protection is used frequently with pipelines that are underground or in water. If done with a new pipeline, it can actually prevent corrosion from forming at all.

3. Corrosion Inhibitors

One other option for corrosion protection methods includes corrosion inhibitors. This method involves adding compounds to pipelines.

They can prevent corrosion from occurring on the inside by creating a thin layer of product.

Corrosion inhibitors are a popular choice because they are cost effective. Take one small step can help prevent costly pipeline issues down the road like oil spills.

4. Coatings and Linings

Using coatings are one of the easiest ways to protect your pipes against corrosion. Coatings and linings can be used on pipes that are above or underground. They frequently are used in combination with cathodic protection.

Some materials that are used to add defense to your pipelines include epoxy and zinc. Sometimes urethane is also used.

These materials must be properly applied and cured to be effective.

5. Abrasive Blasting

Corrosion is tackled by abrasive blasting through use of a high powered machined. The machine throws a certain material at a pipeline.

One benefit of abrasive blasting is that you can control and remove any current corrosion. It is often used first and then followed by another treatment to prevent further corrosion.

Choose Your Corrosion Protection Methods

You are now equipped with five ways to fight corrosion in your pipelines. By following these steps, you will ensure your pipelines remain corrosion free and safe for everyone.

cathodic protection

Posted by & filed under Pipes.

Plant managers and industrial pipeline workers should be aware of all the threats of pipeline corrosion.

About 85% of all steel is under threat of oxidation and galvanic corrosion because it is carbon-based.

Controlling corrosion involves implementing cathodic protection; this utilizes a process of electrochemical reactions, which suppresses oxidation inside a galvanized cell at the anode.

Pipeline managers must have a cathodic protection plan in place.

Cathodic protection applied during the initial construction or installation can extend operation for more than 30 years past the average lifespan.

It’s time to start protecting infrastructure and reducing maintenance costs.

Types of Cathodic Protection

All pipelines and tanks made of steel are subjected to the environment’s harsh elements. You must be proactive before signs of failure show up and it’s too late. Protection is prevention.

Cathodic protection can be applied in two fundamental ways, but they both achieve the same goals of avoiding the oxidation process.

Galvanic Cathodic Protection

Galvanic corrosion involves a system of sacrifice, where two metals are bonded by electrical current, with one metal being substantially more susceptible to corrosion than the other, thereby forcing it to take on all the corrosion.

It’s a very effective way to protect large structures and pipelines made out of metal because the sacrificial anode does not have to be equal in size, just enough to provide a place for the electrochemical process to happen.

Galvanic anodes can be utilized in underground, underwater, indoor, and outdoor applications. There is no additional equipment to buy and no additional power source needed.

Impressed Current Systems (ICCP)

ICCP is most commonly used on large metal buildings and structures, where the coverage is expanded by a process called impressed current cathodic protection.

In this scenario, when electrolyte resistivity is too high, an anode is enhanced through the use of an external DC power supply.

Sometimes an AC transformer is used to provide the DC power, that way the ICCP can stay efficient through the use of solar, wind, or eco-friendly generators, keeping costs low and consistent.

Cathodic Protection Design

To be the best and most efficient, cathodic security frameworks must be comprised of smart design and smart planning.

The best cathodic protection is a tested design that includes:

  • A comprehension of the ecological conditions and the structure to be shielded from erosion
  • Audit of cathodic protection installation for the structure or application
  • Determination of which major cathodic type (Galvanic or ICCP) is appropriate.
  • Finish the cathodic assessment using exhaustive tests and illustrations using the most recent drafting technology.

Contractors must have experience in working with and installing cathodic protection and dealing with corrosion, otherwise a simple mistake can leave you completely vulnerable.

Dynagard’s pipe wear pads are a great alternative for those looking for an affordable solution to protect pipes from wear and corrosion.

Getting the Job Done Right

You have to start your pipeline protection at the beginning of its life, preferably.

Utilize Dynagard’s pipe wear pads during the installation or you might be fighting an uphill battle against corrosion.

Providing protection isn’t just one-and-done, either. You must continue inspecting and maintaining it for the rest of its life.

If you want to learn more about protecting your business, you should contact us. Our wide selection of Dynagard pipe wear pad solutions guarantees that you’ll never be at the mercy of the elements.

pipeline maintenance

Posted by & filed under Pipe Corrosion.

Are you a plant owner or general manager looking for ways to maintain your pipeline?

According to the Pipeline Association for Public Awareness, government statistics show that “a common cause of pipeline incidents is improper or unauthorized digging near a pipeline.” 

Other major causes include “mechanical failure, human error, and corrosion.”

How can you ensure that you’re doing your part to prevent these kinds of incidents?

With pipeline maintenance, of course.

Read on to learn 5 maintenance tips for your pipeline system.

1. Right-of-Way Clearing

An important aspect of pipeline maintenance is right-of-way clearing. This is because a pipe needs a clear path of travel in order to operate the most efficiently and uninhibited.

During right-of-way clearing, trees and roots are removed so that the land near pipes is free of the threats of these conditions.

It’s also important that the right-of-way remains clear so that in the event of an emergency with your pipeline, it’s easily accessible for repair.

2. Hydrostatic Testing

To ensure the strength of the pipes in a pipeline, hydrostatic testing is recommended before and during their use. 

Hydrostatic testing is a procedure where the pipes you will use in your project are connected to one another. They are then filled with water at a higher rate of pressure than they will normally be. 

These high pressures help you see how well your pipeline will perform under heavy use.

Besides doing this before pipes are put in the ground, hydrostatic testing is also used to measure the strength of pipelines over time.

3. Identifying Corrosion

A way to help extend the life of your pipeline is by monitoring your pipes for any evidence of corrosion.

Protecting your pipeline against corrosion begins long before your pipes are put in the ground. Depending on the material your pipes are made out of, you should ensure you’re using an anti-corrosive coating. 

But even then, you still can’t protect 100 percent against corrosion. 

This is because natural conditions and accidents create a threat to your pipes. 

For example, a leak, emergency or natural disaster can cause serious damage. This means you should monitor how these substances impact your pipes. 

One way to address corrosion concerns is to use “pigs”. These are devices used to identify corrosion. They also repair certain issues without losing production time. 

4. Maintain Complete Records

When it comes to maintaining your pipelines, you should keep accurate records.

By doing this, you’ll give others a complete record of the life cycle of your pipeline. Besides keeping a database of site plans and pipeline product guides, you should also take lots of pictures.

This helps when it comes to showing the condition of pipes at installation. It will also serve as an important baseline to determine how quickly your pipes are corroding. 

5. Perform Regular Inspections

Regularly inspecting your pipeline is a great way to stay on top of maintenance issues that may arise.

This means being proactive and using an experienced crew who knows what to look for and what to do based on their observations.

If you’re not performing regular inspections, you put yourself at a greater risk for an emergency situation.

This can be dangerous for your employees and costly to your business – especially if the situation causes your operation to be offline for an extended time.

Wrapping Up: The Importance of Pipeline Maintenance

Pipeline maintenance begins at the planning stages of your operation. It also continues throughout the life of your business.

For more than 15 years, businesses have turned to Dynagard when it comes to corrosion control products. Contact us today to learn more about how we can help protect your pipelines!

pigging

Posted by & filed under Pipes, Uncategorized.

Pigging is a great way to protect your pipes without hurting your activity. Chances are, you’ve used “pigs” in the past.

But did you know there is a smarter way of fighting corrosion?

Intelligent pigging is taking the pipeline world by storm, and for good reason. It is by far the smartest method of finding corrosion and keeping you in business. But what is it, and what do you need to know?

Corrosion Is The Enemy

If you work with pipelines, you know corrosion is the root of all evil.

It makes water unsafe to drink or use and has killed more than 500 people since 1986. It’s a scourge upon our businesses, families, and communities.

In the United States, it’s a real problem. With so many pipelines over 50 years old, we are losing $300 billion per year to old metal.

So fighting corrosion should be priority number one for anybody who works with pipes.

But how do you do it without stalling your business? You can’t shut your pipes down and lose revenue, and wait until the problem happens and becomes more costly.

This is why pigging was invented. This procedure involves checking pipes with devices known as “pigs” to maintain the pipe.

Pigs can be used for a variety of tasks: cleaning, preventing leaks, and avoiding cross contamination with other pipes are all applications of this process.

Pigs have made fighting cross-contamination easier. But intelligent pigs are more than just a convenience: they are a blessing.

Intelligent Pigging

Intelligent pigs are one of the newest innovations in corrosion protection.

As the name implies, these technological wonders are no ordinary swine. Once launched in, they can inspect for deadly corrosion and leaks without interrupting your production cycle.

The techniques are mind-blowing. The old pigs were useful but performed only basic cleaning operation. Smart pigs are far more advanced.

Intelligent pigging can save you from corrosion by using things such as magnetic testing and sound to check for leaks, corrosion, and instability.

Knowing the signs of corrosion is an important way to protect your pipes, home, or business. But that may be easier said than done: if you’re worried about this in the home, you may not check your pipes all that often. And even if you are working with pipelines at a professional level, by the time you see the signs could be too late.

Smart pigs can get a lot of people out of a jam because they can find signs invisible to the human eye.

Conclusion

If you’re worried about the damage caused by pipe corrosion (and as we’ve said, you should be,) then smart pigs will absolutely save you and your business from future costs.

But don’t just trust anybody with this delicate procedure: it’s a complicated matter that requires professional work and equipment to get the job done.

Your pipes (and wallet) will thank you.

 

 

pipeline corrosion

Posted by & filed under Uncategorized.

Corrosion is any pipe line’s enemy, but ignoring the warning signs can cost you more than just money.

Lives are also at risk. These ‘ticking time bombs’ have killed more than 500 people and injured over 4,000 since 1986.

The United States has over 2.4 million miles of pipe, making it the largest network of energy pipelines on Earth.

But here’s the problem: Over 50% of these pipelines are now over 50 years old. With age playing a large role in this corrosion, it’s now more important than ever to take action.

So, where does one start? Keep reading to find out everything you need to know about pipeline corrosion.

What is pipeline corrosion?

It is when the metal of the pipeline reacts to elements such as soil and water. Naturally, it will begin to rust over time, leading to corrosion.

What causes it?

Pipelines can corrode due to any of the following causes:

  • The pH level of the water
  • Water temperature
  • Certain minerals in the water (i.e. high levels of calcium)
  • Too much or too little oxygen in the water
  • Velocity of the water traveling through pipes
  • Exposure to sunlight
  • Underground soil and debris
  • Installation issues
  • High carbon environments (i.e. synthesis gas which causes metal dusting)
  • Impurities in the pipeline (such as impure gas, solids, or liquids)

The warning signs of pipeline corrosion

Be on the lookout for corroding pipelines by being aware of the following warning signs. If you notice any of these, immediate action is vital.

  • Discolored water, particularly brown.
  • Leaks, as they can indicate when a corroded pipe can no longer hold water. If left untreated, leaks can spread and cause more corrosion.
  • Strange-tasting water, which is the result of oxidation. This is the leading cause of corrosion in pipelines and oxidation can be dangerous to your health.
  • Clogged pipes, as this means there is a buildup in the pipeline which could cause an explosion or burst.

What are the effects of corrosion in pipelines?

Chemicals such as copper and lead can enter the water-flow when a pipe is corroded. Both of these can have serious health effects if the problem is not fixed quickly.

Health problems due to copper contamination include gastrointestinal problems. More serious contamination can lead to liver and kidney damage.

Lead contamination can cause kidney problems and high blood pressure in adults. In children, however, it can lead to physical and mental development issues.

Corroded pipes can also greatly affect businesses and the safety of employees. Aging pipelines cause major accidents such as explosions due to ruptures.

Additionally, corroded pipelines can cost companies a fortune. Each year, metal corrosion costs the U.S. economy almost $300 billion.

In 2010, a pipeline accident in Michigan caused 840,000 gallons of crude oil to leak into the Kalamazoo River. This pipeline spill alone cost $800 million to fix.

Don’t let that happen to your company!
