ERW Pipe

We offer ERW Pipe that is available in different sizes and shapes to suit the requirements of clients. The pipes and tubes of 4 inch size (10.2 mm) 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 into a tube which is then allowed to pass the welding electrodes. Copper disks type electrodes are connected to the secondary of a revolving transformer assembly. These make contact on each side of the seam and temperature is raised to the welding point. With the use of cutting tool, the outside flash is removed as the tube leaves the electrodes. Inside flash is wiped out by an air hammer or by passing a Mandel through the welded tube after the tube has been cooled. This is known as Electric Resistance Welded or ERW tube/pipe.
