MS ERW Pipe
MS ERW Steel Pipes are manufactured from premium mild steel coils, cold-formed into round shapes, and welded longitudinally using the Electric Resistance Welding (ERW) process. Known for dimensional accuracy, cost-efficiency, and durability, MS ERW Pipes are ideal for construction, plumbing, scaffolding, and industrial applications where uniformity and reliability matter.

Manufacturing Process
Our MS ERW (Mild Steel Electric Resistance Welded) Pipes are sourced from highly reputed mills that follow a precise and advanced manufacturing process. The production begins with high-quality hot rolled steel coils that are carefully inspected for thickness, strength, and chemical composition. These coils are uncoiled, leveled, and fed into forming rollers that gradually shape the strip into a round tube. Once the edges align, the ERW process uses high-frequency electrical current to heat and fuse the edges together, creating a strong and uniform weld without using filler material. After welding, the seam is trimmed to remove excess flash, and the pipe is cooled to maintain structural integrity. The pipes then pass through sizing and shaping rollers to ensure accurate diameter, wall thickness, and dimensional stability. Each pipe undergoes strict quality tests such as hydrotesting, NDT (Non-Destructive Testing), tensile testing, and visual inspection to ensure durability and leak-proof performance. After testing, the pipes are cut to the required lengths and coated with protective oil or coatings to prevent corrosion. As trusted MS ERW pipe traders, we supply only high-quality, certified pipes suitable for construction, fabrication, plumbing, and industrial applications.

Frequently Asked Questions
What is the difference between ERW and seamless pipes?▼
ERW pipes are made by welding steel strips using high-frequency resistance, while seamless pipes are produced without welding through extrusion. ERW pipes are more economical and offer better dimensional accuracy, making them ideal for medium-pressure applications.
Can MS ERW pipes be galvanized?▼
Yes, MS ERW pipes can be galvanized. Galvanization adds a protective zinc coating that significantly improves corrosion resistance and increases the lifespan of the pipes.
What is the maximum size available?▼
We supply MS ERW pipes ranging from 15NB to 500NB (up to 36 inches), with custom sizes and thickness options available on request.
Are MS ERW pipes suitable for structural applications?▼
Yes, MS ERW pipes are widely used in structural applications such as scaffolding, frames, trusses, and construction projects due to their high strength and uniform wall thickness.
What standards do your MS ERW pipes comply with?▼
We supply pipes that comply with IS:1239, IS:3589, IS:1161, ASTM A53, and API 5L standards, ensuring high quality and performance.
