Cold rolled steel tubes with the following a series of characteristics:

1, after cold rolling pipe organization grain fine, pipes are the superior mechanical properties and physical properties;

2, cold rolling mill for the original pipe wall thickness deviation rectifying ability, geometry size precision, surface roughness is low;

3, including a large deformation, can be up to 70-85%;

4, using the method of cold rolling production pipe can be a lot of the decrease of the intermediate processes, such as heat treatment, pickling, heading, straightening and cutting, and so on, to reduce the metal materials, fuel, electricity and other auxiliary materials and human consumption;

5, with cold rolling method to produce thin wall and thin wall, inside and outside without scratches the surface of high quality steel tubes;

6, can effectively rolling high alloy, low plasticity of all kinds of metal pipe.
