Product Description

Spiral Gaskets

We offer Spiral Gaskets, which are manufactured by spirally winding a pre-formed metal strip and filler on the outer periphery of metal winding mandrels. The winding mandrel outside diameter forms the inner diameter of the gasket and the lamination are continually wound until the outer diameter is attained. These are made using the best-in-class raw material and latest technology pertaining to the industry. Both the inner and outer diameters are strengthening with the help of several plies of metal with no fillers being introduced. This provides higher stability and better compression and sealing abilities. Ratio of the filler to the given gasket width density is varied to control the compressibility.

Technical Specifications

  • Spiral wound gasket without inner and outer ring appropriate for tongue and groove flange and narrow width flange.
  • Spiral wound gasket with outer ring which accurately centers gasket on flange and acts as compression stop.
  • Spiral wound gasket with inner and outer ring, inner ring provides additional compression limiting stop and heat & corrosion barrier. This protects gasket winding and flange erosion.
  • Spiral wound gasket with metal jacketed partition bar welded to spiral wound gasket for use on heat exchanger.
