Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding, generally with a length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, and there are many varieties and specifications. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of the weld seam. Welded pipes with smaller diameters are welded with straight seams, and welded pipes with larger diameters are mostly spiral welded.
