Welded steel pipe refers to steel pipes with seams on the surface that are welded by steel strips or steel plates that are bent and deformed into round or square shapes. The blanks used for welded steel pipes are steel plates or strip steels. With the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welds continues to improve, and the variety and specifications of welded steel pipes are increasing, and seamless steel pipes are replaced in more and more fields. Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes
