Gasket Material

Spiral wound gaskets are used for high temperature and high-pressure applications. The main parts of spiral wound gasket are metallic windings and filler material. The criteria for material selection of windings are: corrosive nature, fluid concentration, operating temperature and material cost. Commonly used material for winding are Stainless steel 304, 316 and 321.Alternate winding materials also can be used depending upon the services. General filler material used are Asbestos and graphite. Graphite filler are recommended for very high temperature application.
