MS ERW Pipe – Manufacturing, Properties, Applications & Udhhyog Supplier Guide 2025
The MS ERW Pipe (Mild Steel Electric Resistance Welded Pipe) is one of the most widely used steel pipes in India. Known for its strength, durability, and cost-effectiveness, it is manufactured by rolling mild steel strips into cylindrical shapes and welding the edges using electric resistance welding (ERW) technology.
At Udhhyog, we specialize in supplying MS ERW Pipes that meet IS 1239, IS 3589, ASTM A53, and other international standards. Whether you need pipes for water supply, structural construction, scaffolding, or industrial use, Udhhyog provides reliable solutions at factory rates.
Focus Keyphrase in Introduction: MS ERW Pipe
What is MS ERW Pipe?
MS ERW Pipe is a steel pipe made from low-carbon mild steel sheets that are rolled and welded through electric resistance. Unlike MS seamless pipes, which are produced from solid billets, MS ERW pipes have a welded seam.
- Full form: MS ERW Pipe = Mild Steel Electric Resistance Welded Pipe
- Material: Mild Steel (Low Carbon Steel)
- Welding Method: High-Frequency Electric Resistance Welding (HFIW)
- Surface Options: Black, Galvanized (GI), Painted, or Coated

Manufacturing Process

The production of MS ERW Pipe is highly efficient and ensures uniform thickness and high strength.
- Steel Coil Selection – Mild steel coils are chosen as per IS/ASTM standards.
- Uncoiling & Slitting – The steel coil is uncoiled and slit into strips of required width.
- Forming – Strips are formed into circular shape by forming rolls.
- Electric Resistance Welding – The edges are welded together using high-frequency current.
- Weld Bead Removal – Extra weld bead is trimmed to create a smooth surface.
- Heat Treatment – Pipes are heat-treated to relieve stress.
- Sizing & Shaping – Pipes are sized into round, square, or rectangular shapes.
- Testing & Quality Check – Each MS ERW Pipe undergoes hydrostatic, ultrasonic, and eddy current tests.
