Overview
This 2-inch nominal pipe size spiral wound gasket is engineered for critical sealing applications in high-pressure and corrosive service environments. Manufactured to stringent HG/T 20631-2009 standards, it is designed to create a reliable, leak-tight seal on flanged connections. The gasket's construction utilizes a resilient metal winding combined with a soft filler, compressed between inner and outer retaining rings to ensure optimal performance under bolt load and system pressure fluctuations. It is suitable for both indoor and outdoor use in demanding industrial settings.
Key Features
Engineered for high-pressure service up to 600 PSI Constructed with corrosion-resistant 316L stainless steel inner and outer rings Features a fluoropolymer (PTFE) filler for broad chemical compatibility
Spiral wound design provides excellent resilience and sealing reliability Manufactured to precise HG/T 20631-2009 industry standards Suitable for use on standard 2-inch flanged connections
