Overview
This D-Shape Metal Spiral Wound Gasket is a precision sealing component engineered for demanding, high-pressure industrial piping systems. It is manufactured to the exacting requirements of the HG/T20610-2009 standard, ensuring dimensional consistency and performance reliability for a nominal pipe size of 10 inches (DN250) and a pressure class of PN100. The specialized D-shaped design, incorporating both inner and outer metal rings, provides superior alignment and prevents over-compression in flange assemblies. Its robust construction delivers exceptional sealing integrity across an extreme thermal range, making it a critical solution for challenging process environments.
