CAZ 600 Spiral-Wound gasket is formed of V-shaped metallic stripe and soft non-metallic filler by means of piled, spiral wound and connected its end and beginning by dot welded. Depend 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, medical and pharmaceutical nuclear power station and navigation, etc.

CAZ 640PL also can be processed for inner and outer ring of spiral wound gasket. We make the inner and outer ring by punched for size small then 14 inch, and by lathe for large sizes. If some material is costly, for example SS304, SS316 etc., we can make it by bending and welding with low cost, if the seal face is narrow.
