Welded steel pipe, also known as welded pipe, is produced by forming a steel plate or strip through crimping and welding. The production process of welded steel pipes is relatively simple, resulting in high production efficiency and a wide range of specifications. It requires less investment in equipment compared to seamless steel pipes. However, it is important to note that the general strength of welded steel pipes is lower than that of seamless steel pipes.
