Overview
This spiral wound gasket is engineered for high-integrity sealing in critical piping and vessel flange connections within industrial processing environments. Manufactured in strict compliance with the HG/T 20631-2009 standard, it is designed to deliver reliable performance under significant pressure and thermal cycling. The gasket is constructed with a 316L stainless steel inner ring and outer windings, encapsulating a compressible graphite filler. This combination creates a robust seal capable of accommodating flange rotation and surface imperfections, making it a trusted component for preventing leaks in demanding service applications.
