  Welded steel pipe used in the billet is steel plate or strip, because of its different welding process and divided into furnace welded pipe, welding (resistance welding) pipe and automatic arc welded pipe. Because of its different types of welding is divided into straight seam ASTM A500 ERW Welded Steel Pipe and spiral welded pipe. Because of its end shape is divided into circular welded pipe and shaped (square, flat, etc.) welded pipe. Welded pipe is divided into the following varieties because of its different materials and uses: Mainly used for conveying water, sewage, gas, air, heating and steam, and other low-pressure fluids and other uses. It represents the material q235a grade steel.

  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 seam welded pipe, which can produce pipe with larger diameter with narrower billet, and can produce pipe with different diameters with same width.
