For
applications with high temperature variations (thermal cycling),
pressure variations, or flange rotation problems, gaskets with adequate
flexibility and recovery are required. Spiral wound gaskets are designed
to meet these demanding conditions. |
Spiral Wounds
Our
Spiral wound gaskets are made of a preformed
metallic strip and a soft filler material (PTFE, Non-Asbestos or Flexible
Graphite), wound together under pressure. The metal strip, in 304, or 316
Stainless Steel, holds the filler resulting in excellent mechanical resistance,
resilience and recovery. An inner and/or outer retaining ring option is
available in 304 Stainless Steel or Carbon Steel.
Sizes
These gaskets are available in standard ANSI
pipe flange dimensions from 1/2” and pressures from 150
psi to 2500 PSI. If you have
special requirements, please use or RFQ page or call us. We can help!
