Overview
This 18-inch spiral wound gasket is engineered for critical sealing applications in high-pressure piping systems. It is constructed to provide a reliable, metal-to-metal seal for ANSI 600-pound class flanges, ensuring leak-free performance in demanding industrial environments. Manufactured in compliance with the SH/T3407-2013 standard, this gasket is designed for both indoor and outdoor use, offering a robust solution for maintenance and new construction projects.
Key Features
Robust 304 stainless steel winding and outer centering ring for structural integrity and easy alignment. Polytetrafluoroethylene (FEP) filler layer provides excellent resistance to a wide range of chemicals and solvents. The outer centering ring ensures proper gasket placement during installation, reducing the risk of misalignment. Engineered for a service rating of 600 PSI at standard temperatures, suitable for demanding process conditions. Durable all-metal construction ensures a consistent seal under bolt load and system pressure cycling.
