35CrMo square steel tube seamless profile pipes cold drawn round tubes professional manufacturer  

Cold-drawn seamless square pipe is a kind of seamless square pipe made by cold-drawing hot-rolled square pipe. The manufacturing principle is that the hot-rolled square pipe is heated, perforated, cold drawn and other process steps, and the section size of the pipe is gradually reduced by drawing force to achieve the required size and accuracy requirements. The process flow of cold-drawn seamless square pipe manufacturing mainly includes the preparation of raw materials, heat treatment, perforation, cold drawing, grinding and surface treatment.

Compared with other types of square tubes, cold-drawn seamless square tubes have the following advantages and characteristics: First, cold-drawn seamless square tubes have higher dimensional accuracy and can meet more stringent dimensional requirements; Secondly, the surface quality of cold-drawn seamless square pipe is better, the finish is high, and it is not easy to produce surface defects; In addition, the cold-drawn seamless square pipe has good mechanical properties, especially in terms of strength and pressure resistance. These characteristics make the cold-drawn seamless square pipe widely used in many fields.
