The cold drawn tube has no oxide layer on the inner and outer walls, no leakage under high pressure, high precision, high finish, no deformation during cold bending, no flaring and flattening
The cracks and the surface have been treated with anti-rust treatment. They are mainly used in mechanical structures, hydraulic equipment and pneumatic or hydraulic components of automobiles and motorcycles, such as cylinders or
Cylinders, etc.
Cold drawn precision seamless steel tube specifications
The basic process of cold drawing is: hot rolled capillary, capillary inspection, grinding, capillary pickling, recheck after capillary pickling, cold drawing, before fine drawing pass
