KLINGERMAXIFLEX

The design principle of the KLINGERmaxiflex
Spiral-Wound Gaskets

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. Inner and outer rings can be fitted which are used for centralizing the gaskets on the face of the flange and protecting the inner windings against erosion. They also act as a compression stop. Maxiflex Spiral Wound gaskets can be manufactured using a range of filler materials according to different service conditions. Maxiflex gaskets can be manufactured to meet all of the international standards such as ASME B16.20, DIN and customer specific requirements.

Flange Surface Finish

Maxiflex gaskets are capable of giving an excellent seal over a wide range of flange surface finishes, but as a general guide we suggest the following:
