Overview
This industrial flange gasket is engineered for high-integrity sealing in demanding piping systems. Designed to meet the exacting requirements of the HG/T20610-2009 standard, it provides a reliable, leak-free seal for critical connections operating under significant pressure and thermal stress. Its spiral wound construction with integrated containment rings offers superior performance and safety compared to standard flat gaskets, making it an essential component for maintenance and new assembly in process industries.
Key Features
D2222 spiral wound design with inner and outer reinforcing rings Constructed from 304 stainless steel windings and a graphite filler Engineered for a nominal pressure rating of PN25 (approximately 363 PSI) Precise 12.99-inch nominal diameter for a perfect fit on specified flanges The outer ring prevents over-compression and aids in installation alignment The inner ring provides radial stability and prevents filler blow-out
Robust construction ensures performance across a wide temperature range
