Welding process of pipe

The characteristics of

Straight seam welded pipe production process is simple, high production efficiency, low cost, rapid development.The strength of spiral welded pipe is generally higher than that of straight welded pipe. The welded pipe with larger diameter can be produced with narrower billet, and the welded pipe with different diameter can be produced with the same width billet.However, compared with straight pipe of the same length, the weld length increases by 30-100%, and the production speed is lower.
