Overview
This high-performance spiral wound gasket is engineered for critical sealing applications in demanding industrial piping and pressure vessel systems. Manufactured in strict compliance with the HG/T 20610-2009 standard, it is designed to create a reliable, leak-tight seal in high-pressure flange connections. The gasket features a robust construction with a 316L stainless steel winding and a polytetrafluoroethylene (PTFE) filler, offering an optimal balance of mechanical strength and broad chemical compatibility. It is suitable for use in both indoor and outdoor installations, providing dependable service across a wide range of operating conditions.
Key Features
Manufactured to the HG/T 20610-2009 industry standard for dimensional consistency and performance. Constructed with a 316L stainless steel outer ring for precise centering and protection against over-compression. Features a resilient spiral wound core of 316L stainless steel wound with a PTFE filler. PTFE filler provides exceptional resistance to a vast array of chemicals, solvents, and corrosive media. The spiral wound design offers excellent recovery and sealing performance under variable pressures and temperatures. Suitable for use in both indoor and outdoor applications without degradation. Designed for a nominal pipe size of 10 inches (DN250) and a pressure class rating of 740 PSI (PN100).
