Characteristics of high-precision cold-drawn tubes Precision cold-drawn tube is a type of cold-drawn tube, which has higher precision compared with ordinary products. What we need to understand is the main characteristics and uses of precision cold-drawn tubes, and the following is a detailed introduction: Precision cold-drawn tube is a kind of high-precision steel tube material processed through a special process, that is, cold-drawn treatment. Therefore, the product has many advantages, including no oxide layer on the inner and outer walls of the tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no cracks in flaring and flattening, etc. It can be seen that our requirements for the inner hole, outer wall size, roughness and other aspects of precision cold-drawn tubes are relatively high to adapt to applications in various occasions. Moreover, practice has found that such products have relatively good effects in applications and are relatively suitable tubes.
