Spiral wound gasket comprise a mix of metallic and filler material. Generally, the gasket has a metal (normally stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flexible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.Spiral wound gaskets are designed for ASME ,DIN,JIS flanges.There are usually 4 types of spiral wound gasket ,R/IR/CG/CGI.
Product Description:
Spiral wound gaskets are designed for ASME B16.20 and ANSI B16.5 flanges. Spiral wound gaskets are available for classes 150 to 2500. Custom filler, winding strip, guide ring and inner ring materials are available upon request.
