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
C-shaped metallic winding core with an outer containment ring Pressure rating of PN63 (approximately 915 PSI) Constructed with 304 stainless steel windings for corrosion resistance Flexible graphite filler provides superior sealability and thermal conductivity Outer ring guides installation and prevents over-compression Engineered for resilience and excellent recovery characteristics Suitable for a wide range of industrial media and temperatures
