SWelded Carbon Steel pipe traight seam welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the pipe with larger diameter can be produced with the narrow billet. The pipe with different diameter can also be produced with the same width. However, compared with the same length of the straight pipe, the weld length increased by 30 to 100%, and the production rate is low.
