ERW Pipes & Tube Mills
ERW pipes and tubes stands for Electric Resistance Welded pipes and tubes, the rectangular strip are fed through a rolling machine that curls the longer sides up toward one another, forming a cylinder. In the ERW process, high-frequency electrical current is passed between the edges, causing them to melt and fuse together, welding it longitudinally across its length, an advantage of ERW pipe is that no fusion metals are used and the weld seam cannot be seen or felt.
Welded pipe manufacturing techniques have improved over the years. Perhaps the most important advancement has been the switch to high-frequency electric currents for welding. Prior to the 1970s, low-frequency current was used. Weld seams produced from low-frequency ERW were more prone to corrosion and seam failure. While manufacturing ERW steel pipes, only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel is used. High performance ERW steel pipes and tubing possess high strength corrosion resistance, high deformability, high strength and high toughness.
ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. Our ERW pipe is available in lengths from single random to 46 foot depending on mill capability. ERW tube is available with various quality in square, rectangular round shaped, in addition Pre-galvanized pipe/tube with offering large combination of thickness as well. Based on the customers’ requirements we can manufacture ERW pipes and tubes of different size and shape. We have a very large production capacity of ERW pipes and tubes with an area of 45000 sq. Meters. We are among the leading manufacturers and suppliers of ERW pipes and tubes in Oman. We are also one of the largest exporters of ERW pipes and tubes in Oman, In addition we are dealing with variety of steel sheets, Z-Purlin, C-Purlin etc.
