Overview
This 12-inch spiral wound gasket is a precision sealing component designed for high-integrity flange connections in demanding industrial piping systems. It is engineered to meet the rigorous ASME B16.20-2007 standard, ensuring compatibility and performance in applications rated for 300 LB pressure classes. The gasket's construction is specifically formulated to handle thermal cycling, pressure fluctuations, and mechanical stress, providing a dependable, leak-free seal in critical process environments.
Key Features
Manufactured to ASME B16.20-2007 standards for guaranteed dimensional accuracy and performance. Designed for 300 LB pressure class flange connections, suitable for high-pressure service. The sealing element combines a wound spiral of Stainless Steel 304 with a flexible graphite filler. Integral inner and outer reinforcing rings constructed from Stainless Steel 304. Reinforcing rings provide gasket stability, prevent over-compression, and aid in centering during installation. Flexible graphite filler offers excellent thermal conductivity and resilience under temperature cycling. Stainless Steel 304 construction provides strong corrosion resistance for extended service life.
