Mechanical structure of cold drawn steel pipe
Jul 12, 2018

Cold drawn steel pipes need to obtain a seamless pipe of better size or good quality to some extent, and must adopt cold rolling, cold drawing or a combination of the two in the process of production. Cold rolling is usually carried out on a two-roll mill in which the steel pipe is rolled in an annular hole formed by a variable-section circular hole groove and a stationary tapered head.


The cold drawing of the cold drawn steel pipe is usually carried out on a single-chain or double-chain cold drawing machine, and the cold drawn steel pipe is produced by drawing, extruding, perforating, etc., and the entire steel pipe surface has no seam steel pipe. It is a circular, square, rectangular steel with a hollow section and no seams around it. The steel tube or the solid tube blank is made into a capillary tube by perforation, and then made by cold dialing.


Cold drawn steel pipe is mainly used for mechanical structure to a certain extent, and the precision cold drawn seamless pipe with high precision of product size and high surface smoothness can effectively select the mechanical structure of precision seamless pipe to some extent. Or hydraulic equipment, etc., can greatly save machining time, improve material utilization, and at the same time help improve product quality.
