In the world of piping systems, choosing the right type of pipe is critical to achieving optimal performance and durability. Two common types of steel pipe, ERW (electric resistance welded) and seamless, each have different properties and applications. Let us take a look at the difference between ERW and seamless pipe, and why Topregal is a leading supplier of both.

Difference between ERW and Seamless Pipe

ERW Pipe:

ERW pipes are produced by welding together a pre-shaped steel strip using high-frequency electric current. This process results in a longitudinal seam along the pipe’s length. ERW pipes are known for their:

  • Cost-effectiveness: ERW pipes are generally more affordable than seamless pipes, making them an attractive option for budget-conscious projects.
  • High strength-to-weight ratio: ERW pipes offer exceptional strength and durability, despite their relatively lightweight construction.
  • Consistency: The welding process ensures a consistent wall thickness and diameter throughout the pipe, contributing to its reliability.

Seamless Pipe:

Seamless pipes are created by drawing a solid steel billet through a series of dies, eliminating the need for welding. This method produces a pipe with a continuous surface, devoid of any seams. Seamless pipes excel in:

  • High pressure applications: Due to their seamless nature, seamless pipes are highly resistant to pressure and are ideal for high-pressure fluid handling systems.
  • Corrosion resistance: The absence of welds makes seamless pipes more resistant to corrosion, prolonging their lifespan in harsh environments.
  • Flexibility: Seamless pipes exhibit excellent flexibility and can be easily bent or shaped as needed.
