Spiral Wound Gasket

Spiral wound gaskets can be used to seal fluid pressure up to 250 bar cryoprnices temperature as low as -200°c and up to elevated temperature of 1000°c. Spiral wound gaskets are widely used in the oil, gas, petrochemical process and engineering industries.the spiral wound gaskets is made up of winding material body and innerouter ring.there are spiral wound gaskets with ss304ss304l tape+graphiteasbestosptfe tape,spiral wound gaskets made of ss316ss316l tape+graphiteasbestosptfe tape,spiral wound gaskets made of ss321 tape+grphiteasbestosptfe tape,spiral wound gaskets made of other metallic tape+asbestosgraphiteptfe tape,spiral wound gaskets winding body with ss304ss304lss316ss316lcarbon steel inner ring,spiral wound gaskets winding body with ss304ss304lss316ss316lcarbon steel outer ring,spiral wound gaskets winding body with both ss304ss304lss316ss316lcarbon steel inner ring and ss304ss304lss316ss316lcarbon steel outer ring.
