Advantages and disadvantages of cold rolled steel pipe process

Cold rolled steel pipe refers to the steel plate or steel strip processed into various types of steel at room temperature through cold drawing, cold bending, cold drawing and other cold processing.

Advantages of cold rolled steel pipe:

The molding speed is fast, the output is high, and the coating is not damaged, and it can be made into a variety of cross section forms to meet the needs of the use conditions; Cold rolling can produce great plastic deformation of steel, thus increasing the yield point of steel.

Cold rolled steel pipe defects:

1. Although there is no hot plastic compression in the molding process, there is still residual stress in the section, which will inevitably affect the overall and local buckling characteristics of the steel;

2. The cold rolled steel style is generally an open section, which makes the free torsional stiffness of the section low. It is easy to appear torsion when bending, and easy to appear bending and torsional buckling when pressurized, and the torsional resistance is poor;

3. The wall thickness of cold rolled steel is small, and it is not thickened at the corner of the connection of the plate parts, and the ability to withstand local concentrated load is weak.
