Overview
Engineered for critical sealing performance in industrial pipe flanges, this metal spiral wound gasket is constructed to the exacting HG/T20610 standard. It is designed to create a reliable, leak-tight seal in high-pressure and high-temperature applications, particularly within stainless steel piping systems. The gasket's robust, layered construction accommodates flange rotation and surface irregularities, ensuring long-term integrity under demanding thermal cycling and pressure fluctuations.
Key Features
Manufactured to HG/T20610 industry standard for dimensional consistency and performance Features a durable inner and outer centering ring for simplified alignment during installation Built with a resilient spiral wound V-profile for superior sealing force and recovery Flexible graphite filler provides excellent conformability and thermal resistance 304 stainless steel windings offer strong mechanical strength and corrosion resistance 316L stainless steel inner and outer rings enhance stability and corrosion protection Suitable for extreme temperature service from cryogenic to high-heat environments
