Properties and Characteristics

Spiral wound gaskets are semi-Metallic products designed for high pressure and temperature applications used in chemical, petrochemical, pharmaceutical, food industries and power plants.

Spiral wound gaskets are one of the most commonly used semi-metal gaskets. The sealing element of the spiral wound gasket consists of a V-shaped metal strip spirally wound in combination with soft sealing material filler. The metal strip provides outstanding resilience, while the flexible sealing 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.

Depending on the application the spiral wound gasket can be specified with outer and/or inner rings or without rings. We also produce OVAL-shaped spiral wound gaskets for the sealing of valve covers or manhole covers.

General Characteristics:

  • The spiral wound gasket can be used to seal fluid pressures up to 250 bar and cryogenic temperatures as low – 200°C and up to elevated temperatures 1100°C by using special metal materials and fillers.
  • Due to its special design the spiral wound gasket is simple to install without causing damage (although extra care should be taken during transportation and installation of large diameter gaskets without guide rings).
  • The outer guide ring serves to locate the spiral element centrally on the flange faces and prevent blow-out.
  • By combining different winding materials and metals the gasket can be tailored to a wide variety of operating conditions.
  • Due to its non-sticking character the gasket is easy to remove after service.
  • The gasket does not cause damage to flange faces.
