This ANSI B 16.5 DN80 (3-inch) pipe flange is a forged carbon steel or stainless steel fitting designed for medium to high-pressure piping systems in oil and gas, chemical processing, and water treatment plants. It features a 190mm outer diameter, 94mm inner diameter, 18mm thickness, and a 4mm bevel edge for weld preparation, ensuring leak-proof joint integrity. The flange includes a 4mm fillet and is manufactured to GB, JB, HGJ, SHJ, ANSI, and ASME standards, with ISO 9001:2000 and CE certification for export compliance.
Available in grades 304/L/H, 316/L/H, 20#15CrMo, and 1Cr18NiTi, it is part of a broader range that includes WNRF, SORF, BLRF, THRF, SWRF, and LJRF types across Class 150 to Class 2500 pressure ratings. The flange is also offered in non-standard sizes from 10mm to 5000mm and weights from 0.5kg to 30 tonnes, catering to custom industrial requirements. Typical industry standards for such flanges include material traceability, hydrostatic testing, and dimensional tolerances per ASME B16.5.
These flanges are critical for connecting pipelines while maintaining leakproofness, enabling easy replacement, separation for inspection, and sealing in industries like refineries, petrochemicals, power generation, shipbuilding, and metallurgy. Buyers typically source them for projects requiring reliable, high-integrity joints in demanding environments. Confirm pressure class, material grade, and dimensional fit before ordering to match system specifications.

Before ordering, verify the flange’s pressure class, material grade, and dimensional specifications to ensure compatibility with your piping system. Request the supplier’s mill test certificates and material traceability documents to confirm compliance with ANSI B16.5 and other applicable standards. Check that the flange’s bevel edge and fillet radius match your welding requirements.
Confirm logistics details such as packaging, which is typically wooden crates or pallets with rust prevention for sea freight. Discuss Incoterms (e.g., FOB, CIF) and payment terms (e.g., TT, LC) with the supplier to align with your import procedures. Lead times may vary based on custom specifications, so request a production schedule upfront.
Inspect the flange upon delivery for dimensional accuracy, surface finish, and material consistency. Request a third-party inspection if required for critical applications. Ensure all documentation, including certificates of conformance and test reports, is provided with the shipment to facilitate customs clearance and quality assurance.
