Overview
This B-Type spiral wound gasket is a precision sealing component designed for high-integrity flanged connections in demanding industrial piping systems. It is manufactured to the HG/T 20631-2009 standard, ensuring dimensional consistency and performance reliability for chemical and petrochemical applications. The gasket is engineered to create a robust, leak-tight seal capable of withstanding significant pressure, thermal cycling, and mechanical stress, making it a critical part for maintenance, repair, and new assembly operations.
Key Features
B-Type construction with a centering internal ring for added stability and installation ease. Rated for 600LB pressure class service, suitable for high-pressure systems. Winding is constructed from 316L stainless steel for excellent corrosion resistance. Graphite filler material provides superior thermal conductivity and resilience across a wide temperature range. The internal ring prevents gasket over-compression and blow-out under pressure cycling. Designed for reliable performance in thermal and pressure cycling environments.
