SPIRAL WOUND GASKETS(SWG)

Spiral wound gaskets consist of a V-shaped metal strip spirally wound in combination with a soft filler material. The metal strip provides outstanding recovery, while the flexible filler guarantees excellent sealing. Due to this combination of materials the spiral wound gasket is suitable for sealing under severely fluctuating temperature and pressure conditions. Compatible with the flange closure in which it is to be used, spiral wound gaskets  can be used over the complete temperature range from cryogenic to approximately 1000°C and in all pressures from vacuum to the standard 2500 psi flange ratings making it a high pressure and high temperature gasket. They are more resilient than any other type of metallic gasket with higher flexibility and recovery characteristics to maintain a seal under variable working condition . They are ideal for hydrocarbon processing and refining, petrochemical processing, chemical processing, power generation, pulp & paper and oil and gas industries. Depending on the application, the spiral wound gasket can be specified with outer and/or inner rings.
