SS 316 Spiral Wound Gasket, CGI, ASME B16.20, 30 IN, CL600
Oct 14, 2025
The 316 stainless steel spiral wound gasket exhibits excellent compressibility and resilience, along with multi-seal design and self-tightening function. It is less sensitive to surface imperfections on flange sealing faces and does not adhere to the flange surfaces, effectively compensating for pressure fluctuations, temperature changes, and mechanical vibrations. Under harsh conditions such as high/low temperatures, high vacuum, shock, or vibration, it maintains superior sealing performance.
The 316 stainless steel spiral wound gasket is widely used in static sealing applications for flange connections in pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, handholes, and other equipment across industries including petroleum, chemical, metallurgy, power, shipbuilding, gas, nuclear energy, aerospace, textiles, pharmaceuticals, and machinery. Its diverse structural forms include basic types as well as various designations and compatible flange sealing surfaces, allowing selection based on specific requirements.
