What Is ERW Pipe

  1. ERW pipes are generally more cost-effective than seamless pipes due to the manufacturing process.

  2. Welding manufacturing process brings a smoother surface finish which easily reduces friction and improves the flow of fluids.

  3. Precise dimensions and uniform wall thickness ensure consistency and accuracy, beneficial for compatibility with fittings.

  4. ERW pipes are suitable for various applications like high-pressure transmission of fluids or gases.

  5. A wide range of sizes and lengths makes the pipes suitable for different applications.

  6. The pipes an be easily welded and fabricated into various shapes or lengths, providing versatility in different projects.

Applications of Carbon Steel ERW Pipes

ERW pipes are broadly used by the industries for their excellent properties, durability, and cost-effectiveness. 

The top application areas of ERW pipes include:

  • Oil Country Tubulars Goods (OCTG)
  • Construction
  • Water and Gas Conveyance
  • Automobile Sector
  • Power Generation Projects.

Manufacturing Process of ERW Pipes

In the Electric Resistance Welding process:

  • Firstly, a flat sheet of steel into a cylindrical shape.
  • Then, a current is passed between the steel cylinder’s two edges to heat the steel to the point.

There is no welding material required in the whole manufacturing process
