00/300902 Description:
For applications with high temperature variations (thermal
cycling), and/or pressure variations, and/or flange rotation problems
etc., gaskets with adequate residual stress (stress
retention), flexibility and recovery are needed. TEADIT spiral-wound
gaskets have been designed to meet these demanding requirements.
Spiral-wound gaskets are made of a preformed metallic strip and a
soft filler material (PTFE or graphite), wound together under pressure,
and optionally with an inner and/or outer guide ring. The metal strip
holds the filler, resulting in excellent mechanical resistance,
resilience and recovery.
