ERW Pipe Manufacturer in India

“Electric resistance welded” is what ERW stands for. In order to create ERW pipes and tubes, metal is first rolled, and then it is longitudinally joined by welding. A welded joint is present in the cross-section of ERW pipes. It can be produced up to a 24″ OD and is made of Strip/Coil. For ERW pipes and tubes up to 21 inches in outside diameter, high-frequency induction welding technology is used. A steel ribbon is dragged through a set of rollers to make an ERW pipe, which is then cold shaped into a tube and fused with electricity. It is primarily used for low- to medium-pressure applications, including moving water or oil. One of the top exporters and manufacturers of ERW pipes stainless steel and tubes to the Middle East.

The steel coil is used to create electric resistance welded (ERW) pipe, and the seam of the weld runs parallel to the pipe. Because the coil’s width and the pipe’s circumference are equal, the diameter can only be 24 inches. However, due to how quickly it is made, it is perfect for big production runs of sections with tiny (= 24 in.) diameters.

In the Gulf, Dubai, UAE, and other MENA countries, Spar Steel is the top scaffolding business for the supply of high-quality goods in a variety of ranges and diameters of ERW/GI/GP Pipes and tubes. According to worldwide standards, Spar Steel is renowned and trusted for producing a variety of steel pipes and tubes, such as MS/ERW Pipes, Black Pipes, GP/GI Pipes, GIS Tubes, and Galvanized Pipes, and ARAMCO Pipes & Tubes.

A few advantages to note with ERW pipe:

  • The production procedure does not involve the usage of fusion metals. This demonstrates how incredibly robust and long-lasting the pipe is.
  • There is no way to see or feel the weld seam. When compared to the double submerged arc welding procedure, which results in a visible welded bead that may need to be removed, this is a significant difference.
  • High-frequency electric currents for welding have improved, making the procedure much simpler and safer.

Cold forming a flat steel strip into a rounded tube and then running it through a succession of forming rollers to create a longitudinal seam is how ERW pipe is made. A high-frequency current is used to simultaneously heat and squeeze the two edges to create a connection. Impurities in the heat-affected zone are extruded during the welding process, but the longitudinal ERW seam does not need filler metal.
