What Is an MS ERW Pipe?
An MS ERW pipe is a mild steel pipe made by cold-forming steel strip or coil into a cylinder and joining the edges with electric resistance welding, without added filler metal. The result is a straight-seam pipe with uniform wall thickness, which is why ERW steel pipe is a standard, cost-effective choice for water lines, scaffolding, structural framing and fencing.

Frequently Asked Questions About MS Pipes & ERW Steel Pipes
Common Queries About Ultramax MS Pipes & ERW Steel Pipes
Find quick answers to the most frequently asked questions about UltraMax MS Pipes & ERW Steel Pipes, including their benefits, applications, and why they’re a top choice for durable construction.
Q. Is UltraMax an ERW pipe manufacturer in India?
Yes. UltraMax, under Adukia Industries, manufactures ERW (Electric Resistance Welded) steel pipes and tubes in-house at our West Bengal facility, rather than trading third-party stock.
Q. What sizes of MS pipes does UltraMax produce?
We manufacture round, square, and rectangular MS pipes up to 150 mm NB (6″) — see the full size chart for exact dimensions and wall thicknesses.
Q. What standards do UltraMax steel tubes and pipes meet?
Our MS steel pipe and tubes are manufactured to IS: 1239, IS: 1161, IS: 3601, and IS: 4923 for air, water, and structural applications.
Q. How do I check the current MS pipe price?
Download our live price list or brochure from this page, or submit an enquiry — pricing is confirmed directly since it moves with steel input costs.
Q. What are UltraMax ERW pipes used for — water, gas, or structural applications?
All three. Our ERW pipes are used for gas and liquid transport, water supply lines, and structural/fabrication work including framing and fencing.
Q. What is the difference between MS pipe and ERW pipe?
MS (mild steel) describes the material, while ERW describes how the pipe is made. An MS ERW pipe is a mild steel pipe formed from strip/coil and joined by electric resistance welding, so the two terms often overlap in the market.
Q. Is ERW pipe better than seamless pipe?
Neither is better in every case. ERW pipes are economical and offer uniform wall thickness for water, structural and general-purpose use, while seamless pipes are usually specified for very high-pressure or critical service.
Q. How do I choose between MS pipes manufacturers in India?
Check that the company manufactures in-house rather than trading, confirm the IS standards it follows, ask how pipes are tested, and match its size range to your project. UltraMax is one of the MS pipe manufacturers in India that meets these checks for round, square and rectangular pipes.
Q. Where can I buy MS pipes in Kolkata?
UltraMax is a Kolkata-headquartered manufacturer and supplier with a manufacturing unit in Purba Bardhaman. Visit the corporate office at 25, Ganesh Chandra Avenue, 4th floor, Paul Mansion, Kolkata - 700013, or call +91 91474 09711.
