Welding Neck Flange
The Huaxi Steel Pipeline Manufacturer Co., Ltd. offers a DN50 (2‑inch) welding‑neck flange that conforms to ASME B16.5 Class 150. It is forged from carbon steel ASTM A105 / SA105, a material widely accepted for high‑pressure pipeline connections. The flange features an oiled and painted surface finish and is supplied with a complete mill‑test certificate issued to ASTM A105 standards. Export packaging is either a wooden pallet or a crate, depending on order size.
Carbon‑steel A105 provides good tensile strength and fatigue resistance, making it suitable for oil, gas, petrochemical and power‑generation services. Typical industry dimensions for a DN50 Class 150 flange include a bolt circle diameter of about 73 mm and eight bolt holes, tolerances that follow ASME B16.5. The forged construction reduces stress concentration compared with cast alternatives, and the oiled coating offers short‑term corrosion protection during handling. Standard packaging protects the flange against deformation during overseas transport.
Buyers such as pipeline contractors, EPC firms and refinery operators select this flange for its proven fatigue performance and compliance with international standards. The supplier provides mill‑test certificates and can arrange third‑party inspection by SGS BV on request. Payment terms are negotiable at buyer’s option, and the company ships worldwide from Leshan, Sichuan. Potential importers should confirm the exact quantity, required certification and preferred Incoterms before placing an order.

This ASME B16.5 Class 150 DN50 welding neck flange is forged from premium A105 carbon steel, designed for high-pressure pipeline connections in oil and gas, petrochemical, and power generation applications. The weld neck design provides superior strength and resistance to fatigue, making it ideal for critical service piping systems. Exported globally in wooden pallet or crate packaging with complete mill test certificates (MTC) per ASTM A105 standards.

Sourcing Welding Neck Flange from Huaxi Steel Pipeline Manufacturer Co., Ltd. - China Import Guide
Before placing an order, verify that the mill‑test certificate references ASTM A105 and confirms the forged construction. Ask the supplier to provide the certificate in PDF format and check the dimensions against the typical bolt circle diameter of 73 mm for DN50 flanges. Confirm any additional surface‑treatment documentation if an oil‑paint finish is required for your project.
Discuss logistics early: request the preferred Incoterm (for example FOB Leshan port or CIF Shanghai) and ask for an estimated lead time based on the order quantity. Payment terms are negotiable at buyer’s option, so obtain written agreement on the agreed method, whether T/T, L/C or another instrument. Clarify whether the wooden pallet or crate packaging meets your freight forwarder’s handling requirements.
Arrange a pre‑shipment inspection if required by your quality‑assurance programme. Request that the supplier or SGS BV conduct a visual and dimensional check and include the inspection report with the shipping documents. Ensure the commercial invoice, packing list and mill‑test certificate are all present to facilitate customs clearance in the destination country.
