What is Spiral Gasket in India

This provides sealing in semi-metallic forms up to pressure or temperatures endured in the industries as Spiral Gasket or Spiral Wound Gasket. This has alternate windings of metal strip with soft filler element like graphite, PTFE or Mica. The spiral design gives from flexibility or elasticity to its surface lightness to promote effective sealing in really tough operating conditions.
These gaskets find their applications most widely in heat exchangers, boilers, pipeline flanges, and pressure vessels. They conform to ASME B16.20 and can withstand pressure ratings to 2500 psi and temperature ratings from cryogenic conditions to 2000°F.
Spiral gaskets include several types, such as:
Type R: Basic spiral wound gasket without inner or outer rings.
Type RIR: Includes an inner ring with better sealing and flange protection.
Type CG: Has a centering ring for easier installation and proper alignment.
Type CGI: Uses both centering and inner ring for improved stability and performance;
The combinations of materials and dimensions vary according to service conditions and compatibility with the media, making them very versatile and reliable for sealing many critical applications.
