We are engaged in offering a wide range of ERW Pipes,
which is available in different sizes, shapes, and other technical
specifications to meet the requirements of our clients. These pipes and
tubes are offered in 4 inch size (10.2 mm) with OD and below, wherein the
strip is fed into a set of forming rolls. The roll comprises horizontal and
vertical rollers so placed as to gradually from the flat strip into a tube.
This further allows to pass the welding electrodes. The copper disks type
electrodes are connected to the secondary of a revolving transformer
assembly. This helps to make contact on each side of the seam and
temperature is raised to the welding point. Further, the outside flash is
removed as the tube leaves the electrodes and the inside flash is wiped out
by an air hammer or by passing a mandrel through the welded tube, after the
tube has been cooled. This formation is known as Electric Resistance Welded
or ERW Tube/Pipe.
