MS ERW Elbow – Complete Guide, Types, Uses, and Price in India
When it comes to piping solutions in construction, plumbing, oil & gas, and industrial applications, MS ERW elbows play a crucial role. They are one of the most widely used fittings for connecting two pipes at an angle, ensuring smooth flow and proper direction of fluids or gases.
In this detailed guide, we will cover everything about MS ERW elbows – meaning, manufacturing process, benefits, applications, types, dimensions, and pricing trends in India.
What is an MS ERW Elbow?
MS (Mild Steel) refers to low-carbon steel, known for its strength, affordability, and easy weldability.
ERW (Electric Resistance Welded) indicates the manufacturing method used to produce the pipe and its fittings. ERW technology involves high-frequency current to join the edges of steel plates, forming strong and durable pipes and fittings.
An MS ERW elbow is a pipe fitting that allows the pipeline to change direction, usually at 45° or 90° angles. It is fabricated from ERW pipes made of mild steel. These elbows are commonly used in low to medium pressure applications across industries.
Features of MS ERW Elbows
High Strength – Provides mechanical strength and durability.
Corrosion Resistant (when coated/painted).
Affordable compared to seamless or alloy elbows.
Easy to Weld and install at project sites.
Available in multiple sizes – from 15mm NB to 600mm NB and above.
Angle Variants – 45°, 90°, and sometimes 180°.
Suitable for various mediums – water, oil, steam, gas, compressed air, etc.
Manufacturing Process of MS ERW Elbow
MS ERW elbows are produced using ERW pipes that undergo bending, forming, and welding. Below is the typical process:
Pipe Selection – ERW pipe is chosen based on size and thickness.
Cutting & Forming – Pipe sections are cut and formed into the desired angle.
Welding – Seam welding or butt welding ensures strength at the joint.
Heat Treatment – Improves toughness and removes stress.
Surface Finishing – Painting, galvanizing, or coating to prevent rust.
Inspection & Testing – Pressure tests, dimensional checks, and quality inspection before dispatch.
