HG/T 20631 Metal Wound Gasket, DN32 900LB, 304/Graphite, for Steel Pipe

Overview

This D-type metal wound gasket is engineered for high-integrity sealing in critical, high-pressure piping systems. Manufactured in strict compliance with the HG/T 20631 standard, it is designed to prevent leaks in flanged connections within industrial processing environments. The gasket features a robust construction with both inner and outer metal reinforcing rings, which provide exceptional containment, prevent gasket blow-out, and offer superior crush resistance under high bolt loads. It is specifically configured for a nominal pipe size of 1-1/4 inches and a demanding pressure class rating of 900LB.

Key Features

D-type construction with integral inner and outer metal containment rings Wound spiral design with alternating layers of metal and filler for resilient sealing 304 stainless steel winding provides excellent corrosion resistance Flexible graphite filler ensures a tight seal across a wide temperature range Reinforcing rings control compression and protect the vulnerable winding edge Suitable for high-pressure applications up to 900-pound class
