Welding Neck Flange
Shanghai Changhao High Pressure Pipefittings Co.,ltd manufactures welding‑neck flanges in both carbon steel (ASTM A105) and stainless steel grades (ASTM A182 F304/F316). The products conform to ASME B16.5, API 6A and ISO 7005 standards and are offered across a typical size range from DN15 to DN200, allowing buyers to select the most appropriate nominal dimension for their system. Each flange features a long tapered hub designed for butt‑weld connection and is supplied with standard export crating or palletised packaging.
The carbon‑steel A105 grade provides high tensile strength and good weldability, while the stainless‑steel A182 grades deliver enhanced corrosion resistance for aggressive environments. Typical industry dimensions for a DN50 flange include a bolt circle diameter of about 73 mm and eight evenly spaced bolt holes, with tolerances defined by ASME B16.5. Optional fusion‑bonded epoxy (FBE) coating can be applied for added long‑term protection in harsh service conditions.
End users such as upstream oil‑field developers, refinery engineers and EPC contractors rely on these flanges for high‑pressure, high‑temperature pipeline sections. The supplier ships worldwide from Pudong, Shanghai, using wooden cases or pallets, and offers flexible payment options at the buyer’s discretion. Prospective importers should confirm the exact size, material grade, coating requirement and preferred Incoterm before finalising the purchase.

Sourcing Welding Neck Flange from Shanghai Changhao High Pressure Pipefittings Co.,ltd - China Import Guide
Validate that the mill‑test certificate cites the correct material grade - ASTM A105 for carbon steel or ASTM A182 F304/F316 for stainless steel - and that it references the forged construction. Compare the supplied bolt circle diameter and hole count against the typical 73 mm BCD and eight‑hole pattern for a DN50 flange to ensure dimensional compatibility with your piping layout. Request any additional coating verification documents if you specify an FBE finish.
Clarify logistics early by agreeing on an Incoterm such as FOB Shanghai or CIF destination port, and ask the supplier for an estimated lead time based on the quantity and material grade selected. Payment terms are negotiable; obtain a written agreement outlining whether T/T, L/C or another method will be used. Confirm that the wooden case or pallet packaging meets your freight forwarder’s handling and stacking requirements.
Arrange a pre‑shipment inspection, either through the supplier’s in‑house team or a third‑party agency like SGS, to verify dimensions, material grade and coating integrity. Ensure that the inspection report, mill‑test certificate, commercial invoice and packing list accompany the shipment to streamline customs clearance in the importing country. Maintaining this documentation trail helps mitigate quality disputes and supports smooth delivery.
