Overview
This industrial-grade spiral wound gasket is engineered for high-integrity sealing in demanding flanged connections. Manufactured to the stringent HG/T20610-2009 standard, it is designed to withstand extreme pressure and temperature conditions common in process industries. The gasket features a robust, layered construction that provides a reliable, leak-free seal, making it a critical component for maintaining system safety and efficiency in both indoor and outdoor installations.
Key Features
Constructed to HG/T20610-2009 industry standard for guaranteed dimensional accuracy and performance. Designed for high-pressure service, suitable for applications up to approximately 914 PSI. Features inner and outer 304 stainless steel rings for enhanced centering, gasket crush resistance, and flange protection. Spiral wound core combines 304 stainless steel windings with a resilient graphite filler for an effective seal. Graphite filler offers excellent thermal conductivity and stability across a wide temperature range. Suitable for use in both indoor and outdoor environments without performance degradation.
