Product Description:

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.

ERW pipes are used in Water Pipelines, Agriculture and Irrigation (Water Mains, Sewerage Systems, Industrial Water Lines, Plant Piping, Deep Tube-Wells & Casing Pipes). Other popular application area includes usage in gas pipe lines (pipe lines for natural gas, LPG and other non-toxic gases). The SW is meant for shallow water applications This could be in a canal, natural stream, culvert, or pipe.

Surface Treatment:

Chromating treatment or anti-finger print

Surface Finished:


Regular spangle is also called normal spangle which is naturally formed without any additional treatment during galvanizing.


The spangle is restrained and formed as mini spangle by reducing the lead content in the zinc liquid or by blowing the zinc powder from the equipment installed on the zinc pot.


The mini spangle is further skin-passed to produce the extra smooth surface.
