Application field of cold drawn tube and strict processing

- May 02, 2019-

In the process of application, cold drawn tubes play an important role in saving steel, improving processing efficiency and saving energy. Products are widely used in automotive, petrochemical, marine, aerospace, pneumatic components, engineering machinery, offshore engineering, machinery manufacturing and other industries.


The cold drawn tube is equipped with an automatic control system and an online quality inspection system during the production process, so as to ensure the stability and reliability of the product quality, and use the cold drawn tube as the raw material for tolerance control and surface bright processing. A high-precision steel pipe material. The precision cold drawn tube has the characteristics of high precision, high smoothness, good cleanness of the inner wall, high pressure and no leakage of the steel tube, no deformation of cold bending, flaring, flattening without cracks, etc., and can be used for various complex deformations and mechanical processing.


The precision cold drawn tube is mainly composed of inner hole and outer wall with strict tolerance and roughness, and the precision is extremely high. Cold-brittle alloy steel with body-centered cubic lattice will change from ductile fracture to brittle fracture when the test temperature decreases.
