Short Description:

Cold-drawn steel pipe is a steel pipe without seams on the surface of the whole steel pipe produced by drawing, extrusion, perforation and other methods. It is a round, square and rectangular steel with a hollow section and no joints on the periphery. The capillary tube is made by perforating steel ingot or solid tube blank, and then made by cold drawing.

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.
