What is the difference between welded steel pipe and welded spiral steel pipe?
Welded steel pipe refers to steel pipe with a welded seam, manufactured by bending steel strip or steel plate into circular, square, or other cross-sectional shapes and then welding them together. The raw material used for welded steel pipe is either steel plate or steel strip. Since the 1930s, driven by the rapid development of continuous strip‑rolling production and advances in welding and inspection technologies, weld quality has steadily improved, leading to an expanding range of grades and specifications. As a result, welded steel pipe has increasingly replaced seamless steel pipe in a growing number of applications. Compared with seamless steel pipe, welded steel pipe offers lower costs and higher production efficiency.
