Overview
This D-Ring metallic wound gasket is engineered for creating a high-integrity seal in industrial flange connections. It is specifically designed for a nominal pipe size of 1.34 inches and is constructed to withstand demanding service conditions involving elevated pressures, high temperatures, and aggressive media. The gasket's robust, spiral-wound design incorporates resilient graphite filler between layers of stainless steel, providing a seal that compensates for flange irregularities and thermal cycling. Compliance with the HG/T20610-2009 standard ensures consistent dimensional accuracy and performance reliability for maintenance and installation projects.
