Production processes for Welded Pipes – IspatGuru
Production processes for Welded Pipes – IspatGuru

The range of pipe diameters produced by the spiral welding process technology lies in the range of around 500 mm to 2,500 mm. The starting material used for spiral welded pipe production is normally wide HR strip with upto 20 mm wall thicknesses. For pipe thicknesses in excess of 20 mm, plates in individual lengths upto 30 m are generally needed.

Less thickness ,pipe,, mainly ERW / EFW or HFW ,welded pipe, are formed by continues rolling method. In this method, a flat metal strip from the strip coil is feed into the series of roller assembled in line. These rollers gradually form the strip in the circular section. At the end of rolling assembly, this ,pipe, is continuously ,welded, by welding machine.

High frequency, welding (HFW) steel ,pipe, is that ERW ,pipe, produced with a welding current ,frequency, equal to or greater than 70 kHZ. Through ,high,-,frequency, current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.
