  • Spiral Wound Gasket
  • Spiral Wound Gasket - SPIRATEC of TECSON are semi-metallic gaskets designed for high pressure and temperature applications. Depending on the application the spiral wound gasket can be specified with outer and/or inner rings. A variety of forms of the gasket is available and these can be manufactured in a variety of materials or sizes to suit requirements.



Description

Advantages
The spiral wound gasket is suitable for use across a wide pressure range and is therefore virtually applicable.
The spiral wound gasket can be used to seal fluid pressures up to 250 bar and cryogenic temperatures as low -200 and up to elevated temperatures 550.
Due to its sturdy 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 gasket 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-adhesive character the gasket is easy to remove after service.
The gasket does not cause damage to the flange faces.
