The cold drawn steel pipe is produced by drawing, extrusion, perforating, etc., and the entire steel pipe has no seams on the surface of the 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 a precision cold drawn seamless pipe for mechanical structure, hydraulic equipment with high dimensional accuracy and good surface finish. The use of precision seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining time, improve material utilization, and improve product quality.
