Flange insulation gasket is mainly used for offshore platform installation, seawater environmental conditions, crude oil refining pipelines, and protection against electrochemical corrosion and electrical spark insulation requirements.

Flange insulation gasket is a specially designed high pressure gasket with a base material of high strength stainless steel coated with epoxy resin on both sides. The pre-turned annular groove penetrates the resin layer to form a certain depth in the stainless steel part, the PTFE spring energy storage seal ring provides excellent sealing effect, and the stainless steel core plays a strong support role.
