The gaskets has a corrugated metal core normally stainless steel or carbon steel, with expanded graphite or PTFE facings. It is new a style gasket with wide chemical compatibility for standard pipe line duties, heat exchangers vessels and reactors.
Suitable for sealing process pipeline (such as natural gas, hydrogen, nitrogen, oxygen, steam), also apply to the large size of the heat exchanger gaskets.
