Carbon Steel Flange
The Carbon Steel Flange from Cangzhou Weiheng Pipe Industry Co., Ltd is a forged pipe fitting made from ASTM A105 carbon steel, designed for high-pressure and high-temperature service in industrial piping systems. It meets ANSI B16.5 and B16.47 standards, making it suitable for oil and gas, petrochemical, water treatment, and power generation applications. This flange is a critical component for creating leak-proof connections between pipes, valves, and other equipment in demanding environments.
Forged from ASTM A105 carbon steel, this flange offers superior strength and durability with a typical carbon content of 0.35% max and a tensile strength of 70,000 psi min, standard for this grade. The material is chosen for its excellent weldability and resistance to low-temperature embrittlement, typical for A105 flanges. Surface finish is usually as-forged or machined to industry standards, with a typical roughness of Ra 3.2 to 6.3 micrometers for sealing surfaces.
These flanges are widely used by EPC contractors, industrial plant operators, and pipeline engineers who require reliable connections in systems operating at elevated pressures and temperatures. The ANSI B16.5 standard ensures dimensional consistency with a typical diameter tolerance of ±0.8 mm and a typical flange thickness tolerance of ±2%. Buyers should confirm the exact pressure class, facing type, and coating requirements before ordering, as these impact compatibility with existing systems.

Sourcing Carbon Steel Flange from Cangzhou Weiheng Pipe Industry Co., Ltd - China Import Guide
Before ordering, verify the exact pressure class, flange type (e.g., weld neck, slip-on), and face type (RF, FF, RTJ) to ensure compatibility with your piping system. Confirm that the material grade (ASTM A105) meets your project’s temperature and pressure requirements, as well as any industry-specific standards such as ASME or API. Request third-party inspection reports or Mill Test Certificates to validate the material properties and dimensional accuracy.
Discuss logistics details such as Incoterms (e.g., FOB, CIF), lead time, and port of shipment with the supplier. For bulk orders, confirm whether the flanges will be shipped in wooden crates, palletized, or loose, and ensure the packaging meets international shipping standards. Clarify payment terms, such as TT (Telegraphic Transfer) or LC (Letter of Credit), and any applicable trade finance options.
Inspect the flanges upon arrival for dimensional accuracy, surface finish, and material markings. Use calipers to verify key dimensions such as outer diameter, bore, and thickness against ANSI B16.5 tolerances. Request a copy of the Mill Test Certificate to confirm compliance with ASTM A105 specifications. For critical applications, consider third-party inspection or non-destructive testing (NDT) to ensure the flanges meet your quality standards.
