How to produce welded steel pipe

For most of customers, we may be quite curious about the production process of welded steel pipe, a kind of basic industrial material. How to produce this long and thick metal? Different pipes have different processing technology and steps. Is it important to know production process? Actually, by production process, we will be more familiar with this kind of production material so that we can choose the suitable one when purchasing steel pipes for our projects that have a high requirement for pipe quality. Now, we will give a brief introduction to customers who are interested in welding pipes from a professional perspective.

The name of straight seam welded steel pipe is mainly because of various types of welding steel pipe such as round steel pipe and the welding line is very obvious on the steel pipe surface. Moreover, there are many kinds and applications of welded steel pipe. How to distinguish them is not an easy job for customers as multiple application ranges of galvanized steel tube. Depending on the different processing technologies, we can make a simple distinguish among them. There are several basic process of straight seam welded steel pipe. First of all, steel pipe manufacturers need to check for the full version of the ultrasonic inspection, which is to ensure that the welded steel pipe has no defects and flaws. After inspection, the steel pipe can be used safely as pipe like square steel pipe and tubing to support heavy buildings and other purposes.

The second process is edge milling of straight seam welded steel pipe. The application of this process is to ensure that the pipe size is to meet the requirements of customers with complex kinds of pipe demands. So the price of welded steel pipe made by customization is usually more expensive than that of standard welded steel pipe. And customers need to be more rational when purchasing steel pipes. The next step is molding. This process can realize the curving edge in advance. In order to guarantee the environmental protection of the steel pipe, after forming, it is necessary for steel pipe manufacturers to deal with environmental issue because environmental protection requirements have a large impact on the price of galvanized steel pipes. Welding phase is the last step that is not simple. It is divided into pre-welding stage, internal welding stage and external welding. After undergoing these processes, the welded steel pipe is basically finished.
