Overview
This D-type metallic wound gasket is a precision sealing component engineered for demanding high-pressure and high-temperature applications in industrial piping systems. It is constructed to provide a reliable, leak-tight seal between flanges, specifically designed for use on ANSI 1-inch (DN25) class 150 (PN16) flanges. The gasket's robust layered design combines the strength of metal with the conformability of a soft filler, making it an ideal solution for preventing fluid or gas loss in critical process environments.
Key Features
D-type construction with integral inner and outer steel rings for enhanced stability and blowout resistance. Wound spiral design with alternating layers of 304 stainless steel and flexible graphite filler. Engineered for high-pressure service, rated for pressures up to 232 PSI (PN16). Excellent temperature resistance provided by the graphite filler and 304 stainless steel components. Designed to conform to flange surface imperfections for a superior seal. Manufactured in compliance with recognized industry standard HG/T20610-2009.
