Introduction to cold drawn steel pipe
purpose
Cold drawn steel pipes are precision cold drawn seamless pipes 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 man-hours, increase material utilization, and at the same time help improve product quality.
High-quality carbon structural steel cold drawn seamless pipes are mainly made of No. 10 and No. 20 steel. In addition to ensuring chemical composition and mechanical properties, hydraulic tests, crimping, flaring, and flattening tests are required.

Product Description Cold drawn steel pipe is a kind of steel pipe, that is, it is classified according to different production processes, which is different from hot-rolled (expanded) pipe. In the process of expanding the diameter of the blank tube or the raw material tube, it is processed by multiple passes of cold drawing, usually on a single-chain or double-chain cold drawing machine of 0.5-100T. Cold-rolled (dial) steel pipe...
