Guide Ring for Spiral Wound Gasket (SMT-212)

Guide ring for spiral wound gasketSpiral wound gaskets are special semi-metallic gaskets of great resilience. They're manufacured by spirally winding a V-shaped or W-shaped metal strip and a strip of non-metallic filler material. Spiral wound gaskets can be reinforced by an outer centering ring and/or inner retaining ring. The outer centering ring controls the compression and holds the gasket centrally within the bolt circle. The inner retaining ring increases the axial rigidity and resilience of the gasket. Spiral wound gaskets can be used for sealing flange joints, manhole and handhold covers, tube covers, boilers, heat exchanges, pressure vessels, pumps, compressors and valves. In indstries such as petrochemical, pharmaceutical, shipbuilding, and food processing, in power industries and nuclear power stations. They are ideal for steam, oil, liquids, gases, acids, alkalines, various organic mediums and solvents.
