Comparison Between ERW and Seamless Steel PipeERW steel pipe is cold-worked and can be straightened online with a reduced diameter, and has an infinite multiple rule, so the straightness is better; seamless steel pipe is formed in a plastic state, plus the single rule (continuous rolling is 3~4 times rule) The straightness of the tube is difficult to control.
Dec 19, 2018 · ERW Welded Steel Pipe Manufacturing Method:When the ERW steel pipe welding process, two electrodes, usually made from copper, are used to apply pressure and current. The electrodes are disc-shaped and rotate as the material passes between them. This allows the electrodes to stay in constant contact with the material to make long continuous welds.
ERW Pipe Electric Resistance WeldedElectric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches. However, because the manufacturing process is fast, it is ideal for large production runs of small (<= 24 in.) diameter sections.
