Overview
This high-performance metal ring gasket is engineered for critical sealing applications in high-pressure stainless steel piping systems. Manufactured in strict compliance with the HG/T20610-2009 industry standard, it is designed to create a leak-tight seal between flanges under demanding service conditions. The gasket is specifically configured for a nominal pipe diameter of 4 inches (DN100) and is rated for PN63 pressure class, making it suitable for robust industrial processes. Its intelligent C-shaped design with an outer reinforcing ring ensures optimal compression and seating within the flange, providing long-term reliability and preventing blow-out under pressure fluctuations or system vibration.
Key Features
