The SW is meant for shallow water applications This could be in a canal, natural stream, culvert, or pipe

Steel Pipes manufacters and Exports huge range of ERW Galvanized Steel Tubes & Steel Pipes. For pipes or tubes size 8 inch (219 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 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 mandnel through the welded tube after the tube has been cooled. This is termed as Electric Resistance Welded or ERW tube/pipe.
