Overview
This industrial-grade metal wound gasket is engineered for high-integrity sealing in pressurized piping and vessel flanges. Manufactured in strict compliance with the HG/T 20631-2009 standard, it is designed to meet the rigorous demands of chemical processing, petrochemical, power generation, and other heavy industrial applications. The gasket's robust construction ensures a reliable, leak-free seal in systems operating at pressures up to 300 pounds per square inch (PSI). Its design and material selection provide superior performance where thermal cycling, system vibration, and chemical exposure are common challenges.
