Spiral Wound Gasket
Spiral Wound Gasket Characteristic
A spiral wound gasket may include a centering ring, an inner ring or both. The outer centering ring enters the gasket within the flange and acts as a compression limiter, while the inner ring provides additional radial strength. The inner ring also reduces flange erosion and protects the sealing element. Resilience and strength make spiral wound gaskets an ideal choice under a variety of conditions and applications. Widely used in refineries and chemical processing plants, spiral wound gasket are also effective for power generation, aerospace, and a variety of valve and special applications. The spiral wound gasket industry is looking for change in the specification covering spiral wound gasket. As environmental regulations and industry requirements become increasingly stringent, new and custom applications are continuing to evolve. Wherever you need a strong, resilient seal, our spiral wound gaskets provide an effective solution.

Flexible graphite has been carefully researched and developed to meet industry's demand for a superior alternative to asbestos filler in spiral wound gaskets. Flexible graphite provides performance that is superior to asbestos, and has been field proven through year of actual service in critical applications throughout the world.
Flexible graphite is pure graphite and is manufactured without the use of filters, resins or binders that could deteriorate at elevated temperature.
PTFE : If PTFE is subjected to temperatures above 250 composition starts to occur slowly, increasing rapidly above 400.
Care should be taken to avoid inhaling the resultant fumes, which may produce unpleasant effects.
