Spiral wound gasket are special semi-metallic gaskets of great resilience. Therefore they are very suitable for applications featuring heavy operating conditions. Spiral wound gaskets are manufactured by spirally winding a V-shaped metal Strip and a strip of non-metallic filler material.

The metal strip holds the filler providing the gasket with mechanical resitanence and resilience. Spiral wound gasket can be reinforeced by an outer centering ring And /or inner retaining ring.the outer centering ring controls the compression And holds the gasket centrally within the bold circle. The inner centering ring increase the Axial rigidity and resilience of the gasket.Spiral wound gasket should always be in contact with Flange and should not protrude into the pipe or project from the flanges.

​

Spiral wound gasket can be used for sealing flange joints, manhole and handhold covers Tube covers, boilers, heat exchangers, pressure vessels,pumps, compressors and valves in industries Such as petrochemical, pharmaceutical,shipbuilding and food processing, in power industries And nuclear power stations. They are ideal for steam,oil,liquid,gases,acids,alkalines,various Organic medium sandsolvents.
