These ANSI B16.5 carbon steel forged flanges from Langfang Dingyang Flange Pipe Fitting Co., Ltd. are manufactured to ASTM A105 and ASTM A350 LF2 material standards, designed for high-pressure piping systems in oil and gas, petrochemical, and power generation sectors. The flanges conform to ANSI B16.5 dimensional standards and are available in Class 150 through 2500 pressure ratings, covering Weld Neck, Slip-On, and Socket Weld configurations. Each unit is precision-engineered for secure, leak-proof connections in demanding industrial environments.
The base material, carbon steel ASTM A105, provides high strength and durability under elevated temperatures, while ASTM A350 LF2 offers low-temperature impact resistance for sub-zero applications. Typical industry specifications for such flanges include a minimum yield strength of 250 MPa and tensile strength of 485 MPa, with standard surface finishes like raised face or flat face for sealing. These flanges are commonly supplied with a protective oil coating to prevent corrosion during transit and storage.
Importers use these flanges in large-scale pipeline projects where reliable pressure containment is critical. The flanges are suited for connecting pipes, valves, and other equipment in systems transporting fluids or gases at high pressures. Buyers should confirm the exact class rating, flange type, and material grade to match their pipeline specifications. Langfang Dingyang Flange Pipe Fitting Co., Ltd. supplies these components from Hebei, China, with options for bulk packaging and export-ready logistics.

Before placing an order, verify the exact pressure class, flange type, and material grade to ensure compatibility with your pipeline system. Confirm whether the flanges meet additional project-specific standards, such as ASME or API, which may be required for certain industries like oil and gas.
Discuss logistics details, including Incoterms (e.g., FOB or CIF), packaging requirements, and lead times. ANSI B16.5 flanges are typically shipped in bulk with wooden crates or pallets to prevent damage. Payment terms such as L/C or T/T should be agreed upon in advance, along with any inspection or testing requirements before shipment.
Conduct quality checks upon receipt, including dimensional verification against ANSI B16.5 and material composition tests for ASTM A105 or A350 LF2 compliance. Request a Material Test Report (MTR) to confirm the chemical and mechanical properties. For critical applications, third-party inspection and hydrostatic testing may be necessary to ensure pressure integrity.
