DynaGard

Corrosion Protection for Pipe Supports

DynaGard is an easy to install, corrosion protection system that isolates the pipe from its support. It consists of a rigid, composite shell, fitted with a corrosion resistant, adhesive liner. At the point where a pipe comes into contact with a support, abrasion associated with pipe vibration or movement can wear away protective coatings over time. Without the benefit of a protective coating, the steel of the pipe is in direct contact with the steel of the support. A corrosion cell is created and the moisture or water that collects at the contact point, or crevice, accelerates corrosion. As a result, pitting or other loss of steel wall occurs, creating the potential for leaks and other
hazards. To avoid corrosion problems associated with pipe supports, companies often insert a “wear pad” to isolate the pipe from its support. Traditional wear pads require several steps to install, increasing the cost greatly. Likewise, traditional wear pads do not have the physical properties necessary to withstand the stress, both mechanical and environmental, that characterizes the interface between a pipe and its support. Consequently, wear pads have to be replaced frequently, driving up maintenance costs.

Unlike traditional wear pads that must be welded or glued, it just takes a minute to peel off the protective release liner and stick the DynaGard onto the pipe.

Installation:

  • Raise pipe off support
  • Clean and dry bottom of pipe
  • Remove DynaGard release liner
  • Stick to pipe at 6 o’clock
  • Pull firmly against pipe
  • Lower pipe back onto support
