The spiral wound gasket is applicable to sealing under heavily alternating temperature or pressure.
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.
Standard Both domestic and international standards products as well as custom-built products are available to meet any customer specific demand. Please indicate your related standard or specific drawing if the gasket is used on the heat exchanger with reinforcing rib.
Application With perfect compression recovery, it is applicable to sealing under heavily alternating temperature or pressure such as the static sealing at flanges of pipeline, valves, pumps, heat exchangers, columns, manhole and hand hole. It has a wide application in petrochemical, mechanical, electric power, metallurgical, ship-building, pharmaceutical, nuclear power and aerospace industries.
