Spiral wound gasket is formed of V-shaped metallic strip and soft non-metallic filler by means of piled,

spiral wound gasket and connected its end and beginning by dot welded. Depend on its excellent compression
resilience, it is suitable for sealing sports 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 factory, power station, metallurgy, shipbuilding, medical and pharmaceutical unclear
