Advantages and disadvantages of cold draw pipe application

Cold-drawn pipe refers to the processing of steel plates or strips into various types of steel at room temperature through cold processing such as cold drawing, cold bending, and cold drawing.
Advantages: fast forming speed, high output, and no damage to the coating, can be made into a variety of cross-sectional forms to meet the needs of the use conditions; cold rolling can cause large plastic deformation of the steel, thereby improving the yield of the steel point.
shortcoming:
1. Although there is no thermal plastic compression during the forming process, there are still residual stresses in the section, which will inevitably affect the overall and local buckling characteristics of the steel;
2. The style of cold-rolled section steel is generally an open section, so that the free torsional stiffness of the section is low. It is prone to torsion when it is bent, and it is easy to buckle when it is compressed, and its torsional performance is poor;
3. The wall thickness of the cold-rolled formed steel is small, and there is no thickening at the corner where the plates are connected, and the ability to withstand local concentrated loads is weak.
