Product Information

Spiral wound gasket: is formed of V-shaped or W-shaped metallic stripe and non-metallic filler by means of lamination, spiral wounding and dot welding its beginning end by dot welding. Depend on its excellent compress resilience, it can sealing spot where the alteration of temperature and pressure is frequent. It can be used as the static sealing parts of pipe, valve, pump, thermal exchange, condensing power, plain hole and man hole of flange, etc.
