ERW Pipes

Electric resistance heat, a completely effective welding process, joins steel sheets to manufacture ERW pipes. Industrial applications, structures, and transportation use accurate and dependable ERW pipes. They are relatively cheaper than seamless pipes and perform similarly.

Surya Group wide range of Structural Steel Hollow Sections under various grades YSt 210/240/310 at works. Along with standard sizes we also manufacture extra light series (up to 1mm thickness) sections. We keep finish goods for all regular sizes and thus require low lead time for delivery. Surya’s product development/application team continuously assess the needs of the market to develop new sizes/value added products such as Hot Dip Galvanized, HRPO, CR & GP Sections.

Special Application – Solar Power Structure

The consumption of non-renewable sources like oil, gas and coal is increasing at an alarming rate, the time has finally come to look after some other renewable sources of energy i.e. Solar Energy. Although many countries have started utilizing solar energy extensively but still they have to go a long way to fulfill their daily demand for energy.

Manufacturing Process of ERW Pipes

ERW pipes are made from HR Coils manufactured & supplied by reputed major steel producers. After being longitudinally slitted & edge preparation, the strip is progressively formed into a circular shape by passing it through a series of forming rolls.

Continuous welding is carried out by a high frequency inducting welding machine, and the seam is formed by fusing the edges without any filler metal. The weld bead reinforcement (inside), is removed. if needed. The welded pipe, after cooling, are cut in appropriate length after attaining its roundness and specified outside diameter.

The pipes are conveyed to the finishing bay for finishing, testing and inspection. Hydro testing of pipes is undertaken to detect leaks and fissures prior to galvanizing and threading. The pipes are subsequently galvanized/black varnished/threaded as per specification/client requirement.

Customer satisfaction drives SURYA in everything that it does. No wonder, its commitment to the high quality of its pipes commences right from the selection of raw material and continues at every stage of manufacturing process till the finished product. The inspection procedures evaluate each pipe for surface finish, perfection of weld, correct diameter wall thickness, length and weight.
