LPG System
  • LPG System
  • LPG System is a Low Pressure service isolationGasket kits designed for electrical flange isolation and general sealing applications.
    This gasket is suitable for use in raised-faceand flat-face flanges in ANSI class 150 and 600 service (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.

Description

Advantages:
The design of LPG incorporated overlapping and offsetting seal grooves. The purpose of this design is to break each layer of laminate within the seal itself there by creating a barrier through which fluid and/or gas cannot migrate. The sealing element can be any elastomeric material as well as more sophisticated Spring-Energized Teflon seals. As a result of this advanced seal design, maintenance free flange isolation and flange face corrosion mitigation are achieved economically.
The LPG is available in both full-face (Type E) and ring style (Type F)configurations. Depending upon the sealing element selected, the LPG is rated for most all hydrocarbon and water service applications.
