SPIRAL WOUND GASKET WRI

ISO 9001 : 2000 Certified

Designed for elevated vacuum, pressures and temperatures, the style WRI modified WR with an internal ring that fills the space between the flanges, avoiding turbulence in the flow of the fluid or as a protection against corrosion or erosion. It is also used as a compression limit when the seating stress is greater than 30 000 psi (210 Mpa).

Second, gaskets with PTFE filler have a tendency to inward buckle thus the use of an inner ring is recommended.

Applications //

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. The spiral-wound gaskets have been designed to meet these demanding requirements.
