The Difference Between the Straight Seam - East Steel Pipe

Seam welded pipe production technology is simple with high production efficiency, low cost and rapid development. The strength of the spiral welded pipe is generally higher than straight seam welded pipe, and can adopt a narrow billet to produce larger diameter welded pipes, and it can also use the billet with the same width to produce the different pipe diameter welded pipe.
