Cold Drawn Precision Steel Pipe

Cold Drawn Precision Steel Pipe (CDPT) is a core precision pipe product launched by Wongsteel (Beijing Yijing Technology) for the high-end manufacturing field. It is divided into two series: seamless and welded. With extreme dimensional accuracy, excellent surface quality and stable mechanical properties, it has become the preferred pipe for high-performance and safety-critical application scenarios, widely serving high-end industries such as automotive manufacturing, hydraulic systems, general machinery, aerospace, and energy equipment.

The product achieves full-scenario coverage in specifications: outer diameter (OD) ranges from 6mm to 120mm, wall thickness (WT) from 0.5mm to 10mm, maximum length up to 12m. Material grades strictly follow international standards such as ASTM, EN, and DIN. Pipe ends can be provided with various processing forms such as plain, beveled, and threaded to meet the installation needs of different working conditions. In terms of processing technology, multiple precision processes such as cold drawing, heat treatment, and straightening are adopted, combined with non-destructive testing technologies such as ultrasonic (UT) and eddy current (ET) to ensure no internal defects and stable performance of the pipe. At the same time, it supports deep processing services such as customized cutting and chamfering to realize one-stop delivery of pipes.

In terms of precision control, cold drawn precision steel pipes achieve industry-leading levels: outer diameter tolerance is controlled at ±0.05mm, wall thickness tolerance at ±8%, straightness ≤0.2mm/1000mm, which can perfectly adapt to high-precision assembly and processing needs, greatly improving the assembly efficiency and operational stability of downstream products. The surface treatment solutions are rich, including bright annealing, heat treatment, phosphate coating, chromated, anti-rust oil, etc., and customized surface treatment is also supported. Exclusive solutions can be provided according to the customer's use environment (such as anti-corrosion, wear resistance, aesthetics) to extend the service life of the pipe.

Compared with ordinary hot-rolled steel pipes, cold drawn precision steel pipes have higher dimensional accuracy, better surface finish, better mechanical properties and ease of machining, which can effectively reduce downstream processing procedures, lower production costs, and improve product safety and reliability. Wongsteel (Beijing Yijing Technology) can provide customized pipe solutions and comprehensive after-sales technical support according to customers' application scenarios, material requirements and precision standards, helping high-end manufacturing enterprises improve their core product competitiveness.
