Overview
This D-shaped spiral wound gasket is a precision sealing component designed for demanding industrial flanged connections. It is engineered to create a reliable, leak-tight seal in high-pressure and high-temperature piping systems, particularly in chemical processing, petrochemical, and power generation applications. The gasket features a robust construction with inner and outer containment rings, providing enhanced stability and critical blowout protection under fluctuating pressures and thermal cycling. It is manufactured to conform to the specific dimensions and performance criteria of industry standard HG/T20610-2009.
Key Features
Engineered for high-pressure service up to 360 PSI (PN25 rating) D-shaped profile ensures proper orientation and fit within corresponding flanges Spiral wound design with a 304 stainless steel winding core for mechanical strength and resilience PTFE (polytetrafluoroethylene) filler layer provides superior chemical resistance against a wide range of corrosive media Inner and outer reinforcing rings made of 304 stainless steel contain the winding and prevent gasket blowout Suitable for a broad temperature range due to the compatibility of metal and filler materials Precise dimensions ensure a correct seal for 8.74-inch nominal bore (DN200) flanges
