Overview
This D-Ring style metal wound gasket is engineered for high-integrity sealing in demanding industrial flanged connections. It is constructed to the HG/T20610-2009 standard for a nominal pipe size of 1.69 inches (DN32) and a pressure class rating of 1,450 PSI (PN100). The design incorporates inner and outer containment rings, which provide stability during installation and prevent the winding from buckling under high bolt loads. This gasket is a critical component for preventing leaks and ensuring system safety in high-pressure and high-temperature piping systems.
