Flange
Wuxi Huaan Flange Co., Ltd. supplies industrial flanges in carbon steel ASTM A105 and stainless steel SS 304, sized from DN15 to DN600 and rated for pressure classes 150 to 2500. These flanges conform to ANSI B16.5, DIN, and BS standards, ensuring compatibility with global piping systems. The product line is engineered for leak-proof sealing under high-pressure and high-temperature conditions, with machining tolerances aligned to industry benchmarks.
The carbon steel variants meet ASTM A105 requirements for forged components, with chemical composition within C 0.35%, Mn 0.60-1.05%, and P 0.04% max. Stainless steel flanges use SS 304 with a minimum 18% chromium and 8% nickel, providing corrosion resistance suitable for chemical and water treatment environments. These materials are standard in industrial piping, and the flanges are typically finished with mill scale removal and surface roughness controlled to Ra 3.2 µm or better.
These flanges are primarily purchased by contractors in oil and gas, petrochemical, and power generation sectors for pipeline infrastructure. Buyers often require certification of material traceability and hydrostatic testing reports. Packaging is export-grade, with rust inhibitors and wooden crates for sea freight. Trade terms typically include FOB Jiangyin or CIF, with MOQs negotiable based on size and grade.

Sourcing Flange from Wuxi Huaan Flange Co., Ltd. - China Import Guide
Before placing an order, verify the material certification (MTR) for each batch, confirming ASTM A105 or SS 304 composition and heat number traceability. Check that the flange size, pressure class, and face type match your piping drawings. Request a sample for dimensional inspection, especially for bolt hole alignment and flange thickness, as deviations can cause installation failures.
Lead time for standard sizes is typically 25 to 45 days from order confirmation. Incoterms are commonly FOB Jiangyin Port or CIF destination port. Payment terms are usually 30% advance, 70% against copy of shipping documents. Confirm whether the supplier handles export documentation and if the packaging meets ISPM-15 for wooden crates. Request a packing list before shipment.
Perform a pre-shipment inspection for surface defects, correct marking, and dimensional accuracy. Use a caliper to check flange thickness and bolt hole spacing against ANSI B16.5. Confirm the presence of hydrostatic test reports for Class 300 and above. Ensure the supplier provides a commercial invoice, packing list, and material certificate. Retain samples for quality audits upon arrival.
