Spiral wound gasket is formed of V-shaped metallic strip and connected its end & beginning by dot welded. 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 excahnger, condensing tower, plain hole and man hole of flange, etc. Please offer the detailed drawing, while the gasket is used in thermal exchange if with some ribs.
