ERW Pipes & Hollow Section Pipes

ERW Pipes & Hollow Section Pipes

ERW Pipes

ERW 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.

Quality assurance begins at the raw material stage and continues righ through all the manufacturing operations, till the Piles are packed for dispatch. The quality assurance department is fully backed by modern laboratory for various matallurgical and chemical tests, and test hourse for testing physical properties. It has been awrded the prestigious ISO 9001:2015 certificate for its quality systems.

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 roundeness and specified outside diameter.

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