ANSI B16.5 Class 150 Welding Neck Flanges
These ANSI B16.5 Class 150 welding neck flanges are forged steel components designed for high-pressure piping systems in oil, gas, and petrochemical industries. The listing specifies carbon steel ASTM A105 and stainless steel ASTM A182 F304 and F316 as primary materials, with the long tapered hub enabling secure butt-weld connections to resist leakage under cyclic loading. The Class 150 pressure rating aligns with standard ANSI B16.5 specifications for moderate-pressure applications.
Material variants extend beyond the listed grades to include ASTM A350 LF2 for low-temperature service, ASTM A694 for high-yield strength, and stainless variants like F316L and F321 for corrosion resistance in aggressive environments. Typical industry practice for welding neck flanges includes a 1:4 taper on the hub, with bore sizes matched to nominal pipe diameters from 1/2 inch to 24 inches. Surface finishes are usually as-forged or machined to a 125-250 Ra microinch standard for weldability.
These flanges are sourced for refinery, power generation, and chemical processing projects where leak-proof integrity is critical. Buyers typically confirm compliance with ASME BPVC Section VIII for pressure vessels or API 605 for large-diameter flanges. Trade terms such as MOQ, incoterms, and lead times should be verified directly with the supplier, as these are not specified in the listing. Packaging is standard export crating to prevent damage during transit.

Sourcing ANSI B16.5 Class 150 Welding Neck Flanges from Shijiazhuang Bang Dong Pipe Trading Co., Ltd. - China Import Guide
Before ordering, verify the supplier’s current production capacity and lead times, as these are not specified in the listing. Confirm whether the flanges are manufactured in-house or sourced from a third party, as this impacts quality control and traceability. Request mill test certificates (MTCs) for the specified materials to ensure compliance with ASTM standards.
Logistics details such as incoterms (e.g., FOB or CIF), packaging standards, and shipping methods should be clarified directly with Shijiazhuang Bang Dong Pipe Trading Co., Ltd. Export packaging typically includes wooden crates or pallets to prevent damage during transit. Lead times may vary based on order volume and material availability, so negotiate these terms upfront.
Quality checks should include dimensional inspections to ensure the flanges meet ANSI B16.5 tolerances for bore, outer diameter, and bolt circle. Request third-party inspection reports for critical applications, particularly for high-pressure or high-temperature service. Documentation such as material certificates, heat treatment records, and NDT reports should accompany the shipment for full traceability.
