Special Shape Spiral Wound Gasket is your good choice.It is usually made of high-quality SUS304, SUS316 ("V" or "W" shape) and other stainless steel winding tapes and graphite, asbestos, PTFE, non-asbestos and other soft materials alternately and overlapped spirally. Use spot welding to fix the metal band. Basic metal wound gaskets without inner and outer rings are generally used in medium and low pressure tongue and groove surfaces and flat or concave-convex flanges.
Performance characteristics:
The spiral wound gasket has good compression performance, good resilience, multi-channel sealing and certain self-tightening function. It is not very sensitive to the surface defects of the flange pressing surface. It does not adhere to the flange sealing surface, which can partially eliminate the pressure and temperature. The impact of changes and mechanical vibration; it can maintain its excellent sealing performance under various harsh conditions such as high temperature, low temperature, high vacuum, shock and vibration.
Equipment used: pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes, etc. in petroleum, chemical, metallurgy, electric power, shipbuilding, gas, nuclear energy, aerospace, textile, medicine, machinery and other industries The static sealing part of the flange connection. Special Shape Spiral Wound Gasket is your good choice.
