The SS ERW Pipe or Stainless Steel Electric Resistance Welded Pipe is one of the most widely used stainless steel piping solutions in India. Known for its durability, smooth finish and cost efficiency, the SS ERW Pipe is manufactured by welding stainless steel strips using high frequency resistance welding technology. This process results in a strong and uniform pipe that is suitable for both low and medium pressure applications.
At Udhhyog we supply a wide range of SS ERW Pipes that meet IS, ASTM and DIN standards. Our stainless steel ERW pipes are used in industries such as construction, water supply, chemical processing, oil and gas and power plants. This article will provide a complete 5000 word guide on SS ERW Pipe covering manufacturing process, properties, sizes, prices, standards, applications and why Udhhyog is the most trusted supplier in India.
What is SS ERW Pipe
SS ERW Pipe stands for Stainless Steel Electric Resistance Welded Pipe. It is manufactured from cold rolled stainless steel coils that are slit and formed into cylindrical shapes and welded longitudinally using electric resistance. Unlike seamless pipes which are made from solid billets, SS ERW Pipes have a visible weld seam but are highly reliable for medium pressure applications.
Key features of SS ERW Pipe
- Smooth internal and external surface finish
- High tensile strength and corrosion resistance
- Cost effective compared to seamless stainless steel pipes
- Wide availability in multiple diameters and thicknesses

Manufacturing Process
- Stainless steel coil selection
- Slitting of coil to required width
- Forming strips into cylindrical pipe shape
- Electric resistance welding of edges
- Weld bead removal and heat treatment
- Pipe sizing and straightening
- Non destructive testing and inspection
- Surface finishing and marking
This process ensures the SS ERW Pipe has uniform thickness and excellent mechanical properties.
Standards and Specifications
- IS 1239 for mild steel and stainless steel pipes in water and gas supply
- ASTM A312 for stainless steel seamless and welded pipes
- ASTM A778 for welded stainless steel mechanical tubing
- DIN and EN standards for global applications
