Description:
Spiral Wound Gaskets are suitable for a wide range of operating conditions and can be adapted to suit almost all applications. The gaskets can seal fluid pressures up to 250 bar and temperature range of -200oC to 1000oC. The gasket is easy to install and remove and will not cause damage to the flange surfaces. A combination of winding materials and metals are available which enable the gasket to meet the requirements of varied operating conditions.
The sealing strips, or fillers, are usually graphite, although other materials such as PTFE may be used, the windings are always s/steal.
