Overview
This D-type spiral wound gasket is engineered for high-integrity sealing in critical flanged connections. It is manufactured to the exacting requirements of the HG/T20610-2009 standard, ensuring dimensional consistency and material quality for reliable performance in demanding industrial environments. The gasket is specifically designed for a nominal pipe size of 0.39 inches and a pressure class rating of PN25, making it suitable for systems operating up to 362.5 PSI. Its robust construction provides a durable, leak-tight seal resistant to thermal cycling and mechanical stress.
Key Features
D-type design with integral inner and outer containment rings Constructed with a 316L stainless steel winding for superior corrosion resistance Graphite filler provides excellent thermal conductivity and sealability Containment rings prevent gasket over-compression and potential blowout Suitable for high-pressure applications up to 362.5 PSI (PN25) Manufactured in compliance with the HG/T20610-2009 industry standard Bulk packaging supports efficient inventory management and project needs
