Cold Drawn Precision Steel Pipe Supply Service

Cold Drawn Precision Steel Pipe Supply Service is a high-precision tubing solution for high-end equipment manufacturing, focusing on bright cold-drawn seamless/welded precision steel pipes, strictly implementing international standards such as DIN2391, DIN2445, EN10305, GB/T3639. Materials cover St35, St45, St52, 10#, 20#, 35#, 45#, 40Cr and other common grades, meeting stringent requirements for dimension and performance in hydraulic systems, automobile manufacturing, construction machinery, aerospace, energy equipment and other fields. The outer diameter is 6–120mm, wall thickness 0.5–10mm, maximum length up to 12m, OD tolerance up to ±0.05mm, straightness ≤0.2mm/1000mm. 

Custom surface treatments such as bright finish, heat treatment, phosphating, chromating, and anti-rust oil are available. We provide pipe-end processing including plain, beveled, threaded ends, and support full-process processing such as cold drawing, heat treatment, straightening, non-destructive testing (UT/ET), custom cutting and chamfering. 

Delivery conditions include BK(+C), BKW(+LC), BKS(+Sra), GBK(+A), NBK(+N) to suit different further processing needs. Relying on cooperation with high-quality domestic steel mills and a mature quality control system, the whole process from raw materials, production, testing to logistics is controllable to ensure stable batch and consistent performance. We provide selection support, customized production, fast delivery and full-process technical response, providing a stable and reliable steel pipe supply chain for equipment and component enterprises, improving product accuracy and yield rate, and reducing comprehensive costs.
