Metal wound gaskets are made by layering V-shaped or W-shaped stainless steel strips with non-metallic fillers and then spirally winding them, with the start and end points spot-welded. They have excellent compressibility and resilience, making them suitable for sealing areas with drastic temperature and pressure fluctuations. They are static sealing elements used in flange connections of pipelines, valves, pumps, heat exchangers, towers, manholes, handholes, etc.

They are widely used in the petrochemical, mechanical, power, metallurgical, shipbuilding, pharmaceutical, atomic energy, and aerospace industries.
