What is ERW steel pipe - www.pipelinedubai electric resistance welding erw welded carbon steel pipe

(ERW) Electric resistance welded pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.

Electric Resistance/ Fusion Welded (ERW and EFW) ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.

Electric Resistance Welded - an overview | ScienceDirect Topics

When electric resistance-welded carbon steel pipe was exposed to aggressive waters, grooves caused by the redistribution of sulfide inclusions along the weld line were formed in the weld. The material at the bond line is anodic to the surrounding material and the result is a V-shaped groove with the apex of the V centered on the bond line.

Without overlapping, the seam is then welded using a process called Electric Resistance. You may now understand where ERW tubing gets its name! During the process of creating ERW tubing, the piping may either be hot rolled or cold rolled, which has electric resistance welding erw welded carbon steel pipe

ERW Pipe | Electric Resistance Welded

Electric 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.
