Quality inspection, pipe cutting, and connection methods of stainless steel water supply pipes
1. The quality inspection of stainless steel water supply pipes can be summarized as follows: check whether the inner and outer walls of the pipe are smooth and flat, whether there are cracks and trachoma, whether the welding parts are smooth, and whether there are signs of depression. At the sam...Read more -
Heating requirements for spiral steel pipe
Before the steel is hot rolled, heating the raw material not only improves the plasticity of the metal, reduces the deformation force, but also facilitates rolling. In addition, during the heating process of steel, some structural defects and stress caused by Tao ingots can also be eliminated for...Read more
