Customized Precise rolling Mild steel Spiral Welded Perforated Tube
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.
