The Alloy C-276 Flange from Zhengzhou Huitong Pipe Fitting Company is a nickel-molybdenum-chromium fitting designed for extreme corrosion resistance in aggressive industrial environments. This flange retains structural integrity under high temperatures and pressures, with a composition tailored to resist pitting, crevice corrosion, and stress corrosion cracking in chloride-laden media. Its versatility makes it a critical component in chemical processing pipelines where standard stainless steels would fail.
Manufactured from Hastelloy C-276, a wrought alloy with typical nickel content of 57% and molybdenum around 16%, the flange meets ASME B16.5 dimensional standards and is available in common nominal sizes from 1/2 inch to 24 inches. Surface finish is standard at 125 to 250 Ra, suitable for gasket seating in high-pressure systems. The material's low carbon content minimizes grain-boundary precipitation, ensuring consistent performance in welded assemblies.
Primary buyers include oil and gas contractors, petrochemical plant operators, and marine engineering firms sourcing fittings for seawater handling systems. Zhengzhou Huitong Pipe Fitting Company offers these flanges in various pressure classes, with typical packaging in wooden crates for export. Confirm incoterms and certification requirements directly with the supplier, as these may vary by order size and destination port.

Before ordering, verify the flange’s pressure class and dimensional compatibility with your piping system. Request the supplier’s mill test certificates for Alloy C-276 to confirm the material’s chemical composition and mechanical properties meet ASME SB575 or equivalent standards. Ensure the flange’s size, schedule, and facing type (e.g., raised face, flat face) align with your project specifications.
Confirm logistics details such as lead time, which may vary based on size and quantity, and the supplier’s preferred port of shipment (e.g., Tianjin or Shanghai). Clarify Incoterms, such as FOB or CIF, and whether the supplier can arrange inland transport from Zhengzhou to the port. Payment terms, such as TT or LC, should also be agreed upon in advance to avoid delays.
For quality assurance, request third-party inspection of the flanges prior to shipment, including dimensional checks, visual examination for defects, and PMI testing to verify the alloy composition. Ensure all documentation, including material certificates, test reports, and packing lists, is provided in English and meets the import requirements of your destination country. Consider specifying additional NDT, such as liquid penetrant testing, for critical applications.
