GA9100 Spiral wound gasket

Spiral wound gasket (SWG) consists of thin metal hoop and nonmetal filler material that are simultaneously wound. The metal hoop is pre-formed in V or W shaped profile, which allows the gasket to act as a spring between the flanges. The hoop also provides the basic structural element for the gasket while the nonmetal filler material seals the flange surfaces that are with small imperfections.

Depending on its excellent compression resilience, it is suitable for sealing spots where the alteration of temperature and pressure are frequent. It can be used as the static sealing element of pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc. It has been widely applied in the fields of petrochemical, mechanical manufactory, power station, metallurgy, shipbuilding, pharmaceutical, nuclear power station and navigation, etc.
