Overview
This D-type spiral wound gasket is a precision sealing component engineered for high-pressure, high-temperature flange connections in industrial piping systems. Designed to meet rigorous industry standards, it provides a robust and reliable metal-to-metal seal that maintains integrity under cyclic loading and extreme service conditions. The gasket's construction incorporates both inner and outer containment rings, a critical feature for controlling compression and preventing sealant extrusion, thereby ensuring long-term leak prevention and system safety.
Key Features
Spiral wound construction with alternating layers of metal and filler Inner and outer carbon steel containment rings for compression control Flexible graphite filler for superior thermal and chemical resistance 304 stainless steel winding for corrosion resistance Engineered for sealing in high-pressure flange faces Prevents gasket blow-out and minimizes creep relaxation Suitable for a wide range of industrial media and temperatures
