Average Galvanized Steel Pipes

The steel 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 induction welding machine, and the seam is formed by fusing the edges without any filler metal. The weld bead reinforcement (outside) is essentially removed, and the weld bead reinforcement (inside) is removed (if needed). The welded pipe, after cooling, is cut to an appropriate length after attaining its specified shape. 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 (process like pickling, rinsing, fluxing, drying, dipping, blowing, dichromating etc.) and threading.

The galvanized steel pipes are extensively used in agriculture, industry and construction activities like scaffolding and casing in bore wells. These are used for conveying water, gas, crude oil and chemicals at various pressures and densities over long distances. Considering the challenging and varied applications, the pipes are produced to meet very high standards of both national and international specifications.
