Overview
This D-type spiral wound gasket is engineered for high-pressure sealing in large-bore industrial piping and flange connections. It is specifically designed for PN10/16 pressure classes, providing a reliable, crush-resistant seal capable of withstanding thermal cycling and mechanical stress in demanding process environments. The unique D-shaped configuration, with integrated inner and outer metal rings, centers the gasket perfectly on the flange, preventing blowout and ensuring optimal sealing performance under variable loads.
Key Features
D-type design with integral carbon steel inner and outer centering rings Spiral wound construction with 304 stainless steel for resilient sealing Engineered for large bore applications up to 25.04 inches Suitable for high-pressure service in PN10 and PN16 classifications Crush-resistant design maintains seal integrity under bolt load Withstands thermal cycling and mechanical vibration Centering rings prevent gasket misalignment during installation
