Cold-drawn steel pipe is a precision cold-drawn seamless pipe with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment. The use of precision seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and help improve product quality.
When cold-drawn steel pipes are produced and formed, they need to go through the pipe-tuning process, heating treatment, piercing technology, hot-rolling process, head treatment, pickling process, phosphating treatment, cold drawing process, annealing treatment, straightening treatment, pipe cutting process, And inspection of finished products, packaging and processing.
