Case Study: GYLON EPIX® 3504 Gas Manufacturer

The filled PTFE sheet gaskets from a variety of manufacturers were experiencing loss of compressive stress resulting in leaks to due gasket creep. The cryogenic environment and thermal cycling caused any gasket that was tested to leak. Live loading the flange assemblies was a common practice to facilitate longer seal life. Live loading is used to help maintain the compressive load on the gasket through the use of spring washers.
