Overview
The D-Ring Gasket is a precision-engineered, metal-wound sealing solution designed for demanding high-pressure and high-temperature flange connections in industrial piping systems. It conforms to the stringent HG/T20610-2009 standard, ensuring dimensional consistency and performance reliability for critical applications. Its construction combines the strength of metal with the sealing resilience of graphite, creating a robust seal that maintains integrity under thermal cycling and variable load conditions.
Key Features
Engineered to PN63 pressure class rating for severe service D-type design incorporates integral inner and outer retaining rings Metal winding and filler are constructed entirely from 304 stainless steel and flexible graphite The inner ring prevents filler extrusion into the pipe bore under high pressure The outer ring provides radial stability and protects the winding during handling and installation Flexible graphite filler offers superior conformability to flange face imperfections Excellent resistance to corrosion, thermal shock, and creep relaxation
