Spiral Wound Gaskets

Spiral Wound Gaskets are manufactured by spirally winding a Vshaped metal strip and a strip of non-metallic filler material. The metal strip holds the filler, providing the gasket with mechanical resistance and resilience. Spiral wound gaskets can be reinforced by an outer centering ring and/or inner retaining ring.

Spiral Wound Gaskets of all shapes and sizes

Spiral Wound Gaskets are manufactured by spirally winding a Vshaped metal strip and a strip of non-metallic filler material. The metal strip holds the filler, providing the gasket with mechanical resistance and resilience. 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 should always be in contact with the flange and should not protrude into the pipe or project from the flange.
Spiral Wound Gaskets 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, liquids, gases, acids, alkalines, various organic mediums and solvents.
ADVANTAGES

  • Sealing under heavy operating conditions.
  • Strong stress compensation, stable and reliable sealing performance even under frequent pressure fluctuation condition.
  • Solid construction provides stability and seallability even when the sealing surfaces are slightly corroded or bent.
  • Easy installation.
