Overview
This D-Ring style metallic wound gasket is engineered for creating high-integrity seals in industrial flanged connections. Specifically designed for 1-inch nominal pipe size (DN25) systems, it is constructed to handle demanding service conditions including high pressure, thermal cycling, and exposure to a wide range of media. Manufactured in compliance with the HG/T20610-2009 standard, this gasket ensures reliability and interchangeability in critical piping applications. Each package contains 25 pieces, providing cost-effective bulk supply for maintenance operations and project installations.
Key Features
Robust triple-layer construction with 304 stainless steel inner and outer rings Dense, flexible graphite filler for superior conformability and seal D-Ring design provides mechanical strength and prevents filler blow-out Rated for pressure classes up to PN25 (approximately 360 PSI)
Excellent resistance to thermal shock and cycling from cryogenic to high temperatures Corrosion-resistant 304 stainless steel components for long service life
Precise dimensions ensure proper fit and compression in standard flange faces
