Spiral Wound Gaskets

Spiral Wound Gaskets

KLINGER Maxiflex

 

Spiral wound gaskets have the ability to recover under the action of fluctuating loads caused by process fluid pressure and temperature changes, flange face temperature variations, flange rotation, bolt stress relaxation and creep.

 

The gasket-sealing element consists of a pre-formed metallic winding strip with layers of a softer, more compressible sealing material which, during compression, is densified and flows to fill imperfections in the flange surfaces when the gasket is seated. The metal strip holds the filler giving the gasket mechanical resistance and resilience.

Maxiflex spiral wound gaskets can be manufactured using a range of filler materials according to different service conditions.

Outer guide rings are fitted to centralise the gasket between the bolts and to act as a compression limiter.

Inner rings are fitted to reduce the gap between the inside diameter of the gasket and the bore of the flange.

 

This reduces turbulence, erosion damage and protects the gasket sealing element from the contained media.

Inner and outer rings are manufactured from a variety of metals to suit particular applications.

 

Below are the most common gasket configurations.
