Import Flange — Buy in Bulk from Supplier in China

The flange offered by Hebei Xingu Flange Forging Co., Ltd is a forged carbon steel or alloy steel component designed for pipe connection in high-pressure industrial systems. Available in standard sizes from 1/2 inch to 24 inches, it conforms to ASME B16.5 and DIN 2527 specifications for pressure classes up to 2500#. The material composition typically includes ASTM A105 for carbon steel and ASTM A182 for alloy steel, with surface finishes ranging from rough forged to machined flat face or raised face.

Forging is the primary manufacturing method used, ensuring superior grain structure and mechanical integrity compared to cast alternatives. The flanges are produced without weld seams, reducing failure risk under cyclic loading. Typical tolerances for face flatness are within 0.1 mm per 100 mm, and bore diameters follow ANSI B16.5 dimensional standards. These flanges are commonly used in oil and gas pipelines, chemical processing units, and steam systems where thermal expansion and vibration resistance are critical.

Buyers in the petrochemical, power generation, and water treatment sectors source these flanges for critical piping joints. Packaging is typically in wooden crates or steel strapping, with each batch labeled by size, material grade, and heat number. Trade terms are negotiable, with FOB Cangzhou Port and CIF options available. Minimum order quantities are not stated but are typically aligned with container load volumes. Buyers should request material test reports and dimensional inspection certificates before shipment.

Hebei Xingu Flange Forging Co., Ltd operates from Zhenggang Road in Cangzhou, Hebei Province, China, a region known for its concentration of forged pipe fitting manufacturers. The company is listed as an imported supplier with harbor trust tier, indicating verified export activity and logistics compliance. No public data confirms production capacity, workforce size, or years in operation. The listing does not reference certifications, client names, or revenue figures, and no response rate or average reply time is provided, suggesting limited buyer interaction history.

The supplier specializes in forged flanges and related fittings, using drop forging and heat treatment processes to meet international dimensional standards. While the listing implies compliance with ASME and DIN norms, no certificates are explicitly confirmed. The absence of response metrics or third-party verification signals suggests buyers must request documentation directly. The company does not appear to offer design services or custom machining beyond standard catalog sizes.
