The welding current in the swing welding of the straight seam steel pipe is slightly larger than that of the traditional welding method; secondly, the elongation of the tungsten electrode in the swing welding of the straight seam steel pipe is determined according to the pipe wall thickness, usually

1. During the steel pipe forming process, the steel plate is uniformly deformed, the residual stress is small, and the surface is not scratched. The processed steel pipe has greater flexibility within the steel pipe size and specification range of diameter and wall thickness, especially in the produ

In our daily life, we will use many water pipes, and the spiral steel pipe is one of them. What should we do if the spiral steel pipe is blocked when we use it? When the pipe is blocked, it will not only affect us It will also have a corrosive effect on some raw materials inside the pipeline. Theref

At present, there are many applications of reinforced 3pe anti-corrosion steel pipes. However, due to the low precision of the wall thickness of reinforced 3pe anti-corrosion steel pipes, there is a phenomenon of uneven thickness, which will have a great impact on the performance of reinforced 3pe a
