Success Story
Natural Gas Pipeline Installations with Syntho-Glass XT
Problem
1275 psi carbon steel schedule 40 natural gas transmission line with 50% wall loss at the ground to air interface. Shutting down was not an option.
Conditions
DOT regulated, high consequence natural gas pipeline located in a residential area next to an interstate highway.
Solution
In order to promote adhesion, the pipe was cleaned by removing rust, paint, and other foreign matter in accordance with Sa2.5, NACE 2 or near white metal (see Figure 1).
Syntho-Steel® Load Transfer Putty fills all pits, dents, and other anomalies effectively transferring the hoop load to the high tensile strength composite (see Figure 2).
Syntho-SubSea® High Compression Kelvar filled Epoxy ensures a water tight seal over the repair area while providing chemical resistance (see Figure 3).
Syntho-Glass® XT Extreme Tensile Strength Composite, a bidirectional fiberglass, permanently repairs and reinforces both the internal and external corrosion damage (see Figure 4).
Result
Syntho-Glass® XT fully restored the pipe's hoop and axial strength to enable operation at full MAOP. Syntho-Glass® XT saved thousands of natural gas home owners from being without service. The gas transmission company saved time, money and maintained good public relations. How can Syntho-Glass® XT help you?
