Difference between ERW, DOM and Seamless Tube Metal May 12, 2015 · Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side-trimmed to control width and condition the edges for welding. The strip then passes through a series of contoured rollers which cold-form the material into a circular (square or rectangular) shape.

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. Types of welded pipe - Threeway SteelIt can also use the same width of billet to produce different-diameter welded pipe. But compared with straight seam pipe of the same length, weld length increased by 30 ~ 100%, and the production rate is lower. As a result, a small diameter welded pipe mostly adopts straight seam welding; Large diameter welded pipe mostly adopts spiral welded.
