The strength of the spiral welded pipe is generally higher than straight seam welded pipe . Larger diameter can be produced by narrow black with spiral weld seam . We can also produce it with different pipe diameter using the same width of black . But compared with the same length of straight seam welded pipe , the length of welding line increased 30-100% , and the production speed is low . Therefore , relatively small diameter welded pipe are mostly adopts the straight seam welded pipe , larger diameter welded pipes are usually spiral welded pipe .
