Spiral wound gaskets are special semi-metallic gaskets of great strength and resilience, therefore they are suitable for use under heavy operating conditions.
Spiral wound gaskets are manufactured by spiral winding V-shaped metal strip and strip of non-metallic filler material. Spiral wound gaskets can be reinforced with an outer centering ring and/or inner retaining ring.
Spiral wound gaskets can be used for sealing flange joints, manhole and handhole covers, tube covers, boilers, heat exchangers, pressure vessels, pumps, compressors and valves.
