The PGE™ was designed to give operators an alternative to the failure prone phenolic-based isolating gaskets. The unique design of the PGE™ system incorporates patented overlapping and offsetting seal grooves. The purpose of this design is to break each layer of laminate within the gasket itself, thereby creating a barrier through which fluid or gas cannot migrate. The sealing element can be any elastomeric material, as well as more sophisticated spring-energized PTFE lip seals. As a result of this advanced seal design, maintenance-free flange isolation and flange face corrosion mitigation are achieved economically. Depending upon the sealing element selected, the PGE™ is rated for most hydrocarbon and water service applications.
This gasket is suitable for use in raised-face and flat-face flanges in ANSI Class 150, 300 and 600 service¹ or equivalent. In addition to providing electrical isolation, the gasket is excellent for isolating flanges made of dissimilar metals or where prevention of flange face corrosion is desired.GPT 1-7_PGE Flange Isolation Kit_12.2016_LR
