Overview
This D-shaped metallic wound flange gasket is engineered for creating high-integrity, pressure-resistant seals in industrial piping systems. It is constructed with alternating layers of 316L stainless steel and flexible graphite, confined by integral inner and outer reinforcing rings. This design is specifically tailored to withstand the thermal cycling and mechanical stress found in demanding process applications, providing a reliable seal that prevents leakage and protects flange faces.
Key Features
Manufactured from corrosion-resistant 316L stainless steel for longevity in harsh environments. Flexible graphite filler provides excellent sealing and thermal conductivity. D-shaped design with inner and outer containment rings for superior radial stability and blow-out prevention. Conforms to recognized international dimensional and material standards for flange compatibility. Engineered for high-pressure service, suitable for systems operating up to 232 PSI. The wound construction allows for compression and recovery during thermal cycling.
