Carbon steel cold drawn tube
Cold-drawn steel pipe is a kind of steel pipe, that is, it is a kind of classification according to different production processes, which is different from hot-rolled (expanded) pipes. It is processed by multi-pass cold drawing in the process of expanding the diameter of the blank or raw material tube, usually on a 0.5-100T single-chain or double-chain cold drawing machine. Cold-rolled (dial) steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, machined pipes, thick-walled pipes, small-diameter cold-drawn pipes with internal molds, and other steel pipes , Also includes carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless steel thin-walled steel pipes, and special-shaped steel pipes. The outer diameter of the cold-drawn steel pipe can reach 6mm, the wall thickness can reach 0.25mm, the outer diameter of the thin-walled pipe can reach 5mm, and the wall thickness is less than 0.25mm. Restricted, its caliber and length are subject to certain restrictions.
