从China供应商批量进口Alloy C-276 Flange

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.

Zhengzhou Huitong Pipe Fitting Company operates from No.168, Guoji Road in Jinshui District, Zhengzhou, Henan Province. The supplier is listed under the harbor trust tier, indicating a baseline level of verification for export readiness. While the response rate and average response time are currently not available, the physical address and industrial focus suggest a specialization in pipe fittings for large-scale projects.

The company’s product line centers on high-alloy fittings for corrosive service, with Alloy C-276 flanges representing a core offering. No additional certifications, production capacity, or client references are stated in the profile, so buyers should request these details directly. The supplier’s location in Zhengzhou, a major logistics hub, may offer advantages for inland transport and export via Tianjin or Shanghai ports.
