Frequently Asked Questions

What are the key specifications and standards for this D-shape metal ring gasket?
This gasket is manufactured to the HG/T20610-2009 standard, designed for a 2 inch nominal pipe size (DN50) and a pressure rating of PN63 (approximately 915 PSI). It is constructed with a 304 stainless steel inner ring, a 316L stainless steel outer ring, and a flexible graphite filler, suitable for temperatures from -450°F to 1500°F.
What are the typical applications or use cases for this specific gasket configuration?
This D-shape, metal-ring-jacketed gasket is ideal for sealing high-pressure and high-temperature flanged connections in stainless steel piping systems, commonly found in chemical processing, petrochemical, and power generation industries. The 304/316L stainless steel and graphite construction provides excellent resistance to corrosion, thermal cycling, and creep relaxation.
How is this item packaged and sold? Is pricing per piece or per package?
This gasket is sold in a convenient pack quantity of 12. The listed price and part number (e.g., D2525) are for a single gasket, but they are shipped in a bulk package containing 12 identical units, which is typical for industrial maintenance and procurement.
