We help you understand the difference between ERW and EFW Pipe and why Topregal is the best choice for all your piping needs.

Difference between ERW and EFW Pipe

What is ERW Pipe?

ERW pipes are manufactured by welding longitudinal seams using electric resistance. This method involves passing high-frequency electrical currents through the metal edges, causing them to heat and fuse together without the need for additional filler material. ERW pipes are known for their:

  • Cost-effectiveness: Due to their efficient production process, ERW pipes are typically more affordable than other types of pipes.
  • Smooth finish: The welding process ensures a smooth and uniform surface, making them ideal for applications requiring precision and aesthetics.
  • Strength and durability: Despite being lightweight, ERW pipes offer excellent strength and durability, suitable for a variety of structural applications.

What is EFW Pipe?

EFW pipes are produced using electric fusion welding. This process involves melting the base metal with a high-energy electric arc, creating a strong bond between the metal pieces. EFW pipes are characterized by:

  1. High pressure and temperature resistance: EFW pipes are designed to withstand high-pressure environments and extreme temperatures, making them ideal for critical applications.
  2. Excellent corrosion resistance: The welding process and the materials used ensure superior resistance to corrosion, making EFW pipes suitable for use in harsh environments.
  3. Thicker walls: Typically, EFW pipes have thicker walls compared to ERW pipes, providing additional strength and durability for demanding applications.

Applications of ERW and EFW Pipes

  • ERW Pipes: Due to their smooth finish and cost-effectiveness, ERW pipes are widely used in automotive, construction, and engineering industries for fencing, scaffolding, and pipelines for water and gas.
  • EFW Pipes: Given their resistance to high pressure and corrosion, EFW pipes are commonly used in oil and gas industries, power plants, and chemical processing facilities.
