AlloY B Flange
The Alloy B Flange from Zhengzhou Huitong Pipe Fitting Company is a nickel-molybdenum alloy component (UNS N10001) designed for extreme corrosive environments. It contains Ni as the balance element, with Mo at 26-30% and Fe at 4-7%, delivering exceptional resistance to hydrochloric acid and other reducing media. This flange adheres to ASME B16.5 standards and is available in pressure ratings from 150# to 2500#, ensuring compatibility with high-pressure pipeline systems in chemical, petrochemical, and pharmaceutical applications.
Alloy B, often referred to as Hastelloy B, is a solid-solution nickel-molybdenum alloy known for its resistance to pure hydrochloric acid at all concentrations and temperatures. Typical industry applications include heat exchangers, reactors, and distillation columns where metallic contamination must be minimized. The material’s uniform composition and absence of chromium make it particularly suitable for reducing environments, though it is less effective in oxidizing conditions. Standard grades for similar applications include UNS N10001 for flanges and UNS N10629 for fittings, with ASTM B366 being a common specification for forged components.
These flanges are used by chemical processors, oil and gas operators, and pharmaceutical manufacturers who require reliable connections in aggressive service. Buyers typically source them in bulk for large-scale projects, with packaging and handling tailored to prevent damage during transit. The supplier’s location in Zhengzhou, a hub for industrial pipe fittings, ensures access to logistics networks for efficient export. Confirm pressure ratings, dimensional tolerances, and surface finish requirements before ordering to match project specifications.

Sourcing Alloy B Flange from Zhengzhou Huitong Pipe Fitting Company - China Import Guide
Before ordering Alloy B Flanges from Zhengzhou Huitong Pipe Fitting Company, verify the material test certificates (MTCs) to confirm compliance with UNS N10001 and ASME B16.5. Ensure the pressure rating and dimensional tolerances match your pipeline specifications, as mismatches can lead to leaks or structural failures in high-pressure systems. Request third-party inspection reports if available, particularly for critical applications in chemical processing or petrochemical plants.
Confirm logistics details such as lead time, which can vary based on flange size and quantity. Standard lead times for alloy flanges may range from 4 to 8 weeks, depending on production schedules and raw material availability. Clarify Incoterms (e.g., FOB Zhengzhou or CIF destination port) and payment terms (e.g., T/T 30% deposit, 70% before shipment) to avoid delays. Packaging should be robust to prevent damage during transit, with wooden crates or pallets recommended for heavy flanges.
Conduct quality checks upon receipt to verify dimensions, material composition, and surface finish. Use calibrated tools to measure flange diameter, thickness, and bolt hole spacing against ASME B16.5 tolerances. For corrosion resistance validation, perform a hydrostatic test or request a sample for laboratory analysis. Ensure all documentation, including MTCs, inspection reports, and compliance certificates, is provided and matches the supplied material. Address any discrepancies with the supplier before installation.
