Spiral Wound Gasket

Gasket using in alternating temperature or pressure. As flanges of pipeline, valves, pumps, heat exchangers, columns and so on.

 

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.

2.Application      With perfect compression recovery, gasket 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. The gasket has a wide application in petrochemical, mechanical, electric power, metallurgical, ship-building, pharmaceutical, nuclear power and aerospace industries.
