- Jun 07, 2020-

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.
