spiral wound gasket

1. Structure The laminated V-shaped or W-shaped stainless steel tapes and non-metallic filler are spiral wound into gasket and both ends are spot welded. Semi-metallic and metallic gaskets for higher temperature and higher pressure applications2. Application(1)With perfect compression recovery,gasket is applicable to sealing under heavily alternatingtemperature or pressure such as the static sealing at flanges of pipeline, valves, pumps, heat exchangers, columns, manhole and hand hole.(2)The gaskethas a wide application in petrochemical, mechanical, electric power, metallurgical, ship-building, pharmaceutical, nuclear power and aerospace industries.
