Import Ansi Socket Weld Neck Flange High Quality — Buy in Bulk from Supplier in China

The ANSI Socket Weld Neck Flange from Jinan Shuangke Forging Machinery Co., Ltd. is a forged carbon steel component designed for high-pressure piping systems, compliant with ANSI B16.5 standards. It features a socket weld connection, which allows for smooth bore alignment and reduced turbulence, making it suitable for applications with high flow rates. The flange’s neck design provides reinforcement against bending stresses, while the raised face ensures a tight seal with gaskets under typical pressures up to 2500 psi.

Forged from ASTM A105 carbon steel as a standard material, the flange undergoes heat treatment to relieve internal stresses and improve grain structure. Surface finishes meet typical ANSI requirements, with a standard phosphate coating for corrosion resistance in outdoor or humid environments. The socket depth and diameter are machined to precise tolerances, with standard sizes ranging from 1/2 inch to 24 inches NPS, though Jinan Shuangke can produce custom dimensions on request.

These flanges are primarily used in oil and gas pipelines, chemical processing plants, and water treatment facilities, where leak-proof connections are critical. They are compatible with seamless or welded pipes and can be paired with slip-on or threaded flanges in mixed systems. Buyers should confirm the exact material grade, pressure class, and dimensional specifications, as the supplier’s standard offerings may not cover all ANSI classes without prior arrangement. Shipping is arranged from Jinan, Shandong Province.

Jinan Shuangke Forging Machinery Co., Ltd. is based in Guanzhuang Industrial Park, Zhangqiu City, Jinan, Shandong Province. The company specializes in forging and machining pipe fittings, including flanges, elbows, and tees, with a focus on ANSI, DIN, and JIS standards. Its production capabilities include hot forging, heat treatment, and precision machining, supported by in-house quality control for dimensional and material verification.

The supplier holds an imported tier classification with a harbor trust level, indicating a stable track record in industrial supply. While the profile does not list active certifications like ISO or CE, the company states compliance with multiple international standards for its products. Buyers should request current third-party inspection reports or material test certificates (MTCs) to confirm adherence to project specifications.
