Import Forging Carbon Steel Flange — Buy in Bulk from Supplier in China

The forging carbon steel flange supplied by Shanxi Baoduanf Lange Co., Ltd. is a cast‑forged component designed for high‑pressure piping systems. It is offered in nominal bore sizes from ½ inch up to 72 inches and is manufactured from carbon steel grades Q235, A105, 16MN and 20#. The flange conforms to pressure classes ranging from 150 to 2500, suitable for a wide span of industrial pressures. Precision forging enhances its mechanical strength and dimensional stability.

These grades are standard in the oil‑and‑gas and construction sectors, providing tensile strength and impact resistance required for demanding environments. Typical industry practice includes a surface treatment such as zinc plating or shot blasting to improve corrosion resistance, although the supplier lists optional treatments. The product follows the ASME B16.5 standard for flange dimensions, which defines bolt circle diameters and bolt hole counts for each size. Tolerances are generally ±0.1 mm for critical dimensions, a typical precision for forged flanges.

End users include pipeline contractors, refinery engineers and plant maintenance teams who need reliable flange connections. The supplier mentions flexible minimum order quantities and offers FOB or CIF shipping terms, allowing buyers to choose the most suitable logistics arrangement. Certification compliance is asserted, so purchasers should request the relevant test reports to confirm conformity. Payment terms are negotiated per order, and buyers are advised to verify incoterms and lead times directly with the supplier.
