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
