Technical requirements of straight seam welded pipe: Technical requirements and inspection of straight seam welded pipe According to the GB3092 "Welded Steel Pipe for Low-Pressure Fluid Transport" standard, the nominal diameter of the welded pipe is 6~150mm, the nominal wall thickness is 2.0~6.0mm,

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
