What is Stainless Steel ERW Pipe?
Stainless Steel ERW (Electric Resistance Welded) Pipe is manufactured by forming stainless steel strip or coil into a cylindrical shape and welding the longitudinal seam using electric current pressure without filler metal.
Key Features of ERW Pipes
- Uniform wall thickness
- Strong longitudinal weld seam
- Smooth internal surface finish
- Cost-effective compared to seamless pipe
- Suitable for low to medium pressure applications
Common Applications
- Water supply systems
- Oil and gas pipelines
- Chemical processing plants
- Pharmaceutical industries
- Food and dairy processing units
- Structural and construction projects
