Overview
This metal spiral wound gasket is engineered for high-integrity sealing in critical process piping systems. Manufactured in strict compliance with the HG/T20610-2009 standard, it ensures dimensional accuracy and reliable performance in demanding industrial environments. The gasket is specifically designed for use with 2.5 inch NPS flanges operating at a nominal pressure rating of PN 16 (approximately 232 PSI). Its robust construction provides a resilient, leak-tight seal capable of withstanding thermal cycling, vibration, and system pressure fluctuations common in chemical, petrochemical, and power generation applications.
Key Features
Precision-wound spiral construction for superior sealing resilience 304 stainless steel inner and outer rings for precise centering and bolt load distribution Primary sealing element wound from 304 stainless steel with a PTFE (polytetrafluoroethylene) filler
Excellent chemical resistance provided by the inert PTFE filler material
Designed to seal effectively on standard raised face flange connections
Individually packaged to prevent damage and contamination
