ERW Galvanized  Steel Pipe

image008


Steel Pipes manufacturers and Exports huge range of ERW  Galvanized Steel Tubes & Steel Pipes.

For pipes or tubes size 4 inch (10.2mm) OD and below, strip is  fed into a set of forming rolls which consists of horizontal and vertical  rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks  connected to the secondary of a revolving transformer assembly. The copper disk  electrodes make contact on each side of the seam and temperature is raised to  the welding point. Outside flash is removed by a cutting tool as the tube  leaves the electrodes, inside flash is removed either by an air hammer or by  passing a mandrel through the welded tube after the tube has been cooled. This  is termed as Electric Resistance Welded or ERW tube/pipe.
