Overview
This spiral wound gasket is engineered for high-pressure, high-integrity sealing in critical industrial flange connections. Designed to the HG/T20610-2009 standard, it is suitable for PN63 pressure class service, which corresponds to a nominal pressure rating of approximately 915 PSI. The gasket features a nominal pipe size (NPS) of 2.6 inches. Its robust metal-and-filler construction ensures a reliable, leak-free seal in demanding applications involving thermal cycling, high pressure, and challenging media.
Key Features
Engineered for PN63 pressure class service, suitable for systems up to approximately 915 PSI. Constructed with a 304 stainless steel inner and outer ring for structural integrity and corrosion resistance. Features a spiral wound PTFE (polytetrafluoroethylene) filler for superior chemical resistance and sealing performance. Conforms to the HG/T20610-2009 standard, ensuring dimensional consistency and reliable performance in standardized flange assemblies. The spiral wound design provides excellent resilience and recovery under bolt load, maintaining a tight seal. Ideal for use in systems with thermal cycling and variable pressures.
