Overview
This industrial-grade spiral wound gasket is engineered for high-performance sealing in critical piping and vessel flanged connections. Manufactured in strict compliance with the HG/T 20631-2009 standard, it is designed to withstand demanding pressure and temperature conditions while providing a reliable, leak-tight seal. The 6-inch nominal size and 150-pound pressure rating make it a standard solution for a wide range of process applications. Its construction ensures long-term durability and consistent performance in both indoor and outdoor industrial environments.
Key Features
Engineered to the HG/T 20631-2009 standard for assured dimensional accuracy and performance. Rated for service up to 150 pounds per square inch (PSI) on standard flanges. Features a polytetrafluoroethylene (PTFE) filler for superior resistance to a broad spectrum of chemicals and corrosive media. Built with a C2230 winding configuration, incorporating a 304 stainless steel inner ring and outer ring for enhanced gasket stability and crush resistance. The metal winding and rings provide structural integrity, preventing blow-out under pressure fluctuations and misalignment. Suitable for use in both indoor and outdoor installations without performance degradation.
