ERW - FAQs

ERW stands for Electrical Resistance Welding. This technique uses an electrical current to weld metal such as steel without compromising the metal’s integrity.

The biggest difference between ERW and seamless pipes is the method of fabrication. ERW pipes or tubes are manufactured by welding pieces of steel longitudinally using an electrical current. ERW tubes therefore have a seam, even though it’s almost invisible. Seamless pipes are produced without welds or seams.

Given their loadbearing capacity, superior strength and resistance to corrosion and buckling, and excellent machinability, ERW pipes are suitable for a diversity of applications in a wide range of industries. You can find ERW tubes used in agriculture, construction, oil and gas, furniture manufacturing, automotive, and other industries.

Yes, ERW steel is known for its weldability and machinability.
