Product Description
Our Cold Drawn Seamless Pipe is precision-engineered for applications requiring tight tolerances, superior surface finish, and high mechanical strength. Through a cold drawing process, the pipe achieves exceptional dimensional accuracy, smooth surface (Ra ≤ 1.6μm), and improved tensile strength—up to 20% higher than hot-rolled equivalents. Ideal for hydraulic cylinders, precision shafts, automotive components, and high-pressure machinery, these seamless tubes eliminate weld failure risks and ensure long-term reliability. Made from high-quality carbon steel (20#, 45#, A106 Gr.B), and compliant with ASTM A106, GB/T3639, DIN 2391, our pipes are available in OD 10–200mm, WT 1–20mm. Optional services include cut-to-length, beveled ends, anti-rust oil, and custom packaging. Trusted by global manufacturers for consistent quality and on-time delivery.
