Fluid pipe is a kind of pipe with relatively high requirements. Some are seamless pipes and some are straight seam welded pipes. However, sometimes the inner wall of the fluid pipe welding production line may be scratched. So how to prevent the inner wall from scratched during the production of fluid pipe?

Since prevention is required, we should first know why the inner wall of the fluid pipe welding production lineis scratched during pipe welding. There are two possibilities here. One is the scratch caused by the contact between the forming pipe and the welded pipe mold and the inner surface of the steel strip. The other is that the welding fails to meet the standard, causing the core rod to be pulled when the inner surface is leveled, and finally causing the inner wall to be scratched.

It's much easier for us to handle the problem properly and effectively after knowing the reason. The solution to problem 1 is to hang a layer of plastic film on the surface of the forming pipe mold, which can reduce the risk of the inner surface of the steel strip being pulled. The solution to problem 2 is to improve the welding quality, strengthen the technical improvement, improve the front arc of the core rod, improve the surface hardness of the core rod, and increase the surface smoothness, which can also reduce the risk of scratching on the inner wall of the steel pipe.

If you are a manufacturer of fluid pipes, and the inner wall of your fluid pipe welding production line is scratched, how do you deal with it? Welcome to talk and learn together, make progress together, and produce high-quality fluid pipes.
