MS Pipe and Fittings – Complete Guide
Mild Steel (MS) pipes and fittings are among the most widely used materials in plumbing, construction, industrial applications, and infrastructure projects. Their affordability, durability, and versatility make them a preferred choice for engineers, contractors, and manufacturers. In this detailed guide, we will explore MS Pipe and Fittings, their types, applications, benefits, and pricing trends.
1. What are MS Pipes and Fittings?
MS pipes are Mild Steel pipes made from low carbon steel, typically containing 0.05% to 0.25% carbon. This low carbon content makes the steel more ductile, easy to weld, and workable, which is why MS pipes are used in almost every sector.
MS Fittings are the accessories or components used to join, bend, or extend the MS pipes. These fittings include elbows, tees, reducers, couplings, flanges, unions, sockets, and nipples, which help in controlling the flow of liquids and gases.
2. Why Choose MS Pipe and Fittings?
There are multiple reasons why industries prefer MS pipes and fittings:
Durability – Long-lasting material resistant to moderate pressure and temperature.
Easy Fabrication – Can be cut, bent, and welded easily.
Cost-Effective – Much cheaper compared to stainless steel or copper.
Corrosion Protection – Available with galvanization or coatings for long-term use.
Wide Availability – Manufactured across India and globally in different sizes.
Versatility – Suitable for water supply, gas pipelines, sewage, fire-fighting, and structural purposes.
3. Types of MS Pipes
MS pipes come in different categories depending on their application:
MS Black Pipes – Plain mild steel pipes without coating, used in water supply and structural applications.
MS Galvanized Pipes (GI Pipes) – Coated with zinc for protection against rust, commonly used in plumbing and outdoor applications.
MS ERW Pipes – Electric Resistance Welded pipes, known for precision and strength.
MS Seamless Pipes – No welding joints, suitable for high-pressure applications.
MS Hollow Section Pipes – Square, rectangular, or circular pipes used in construction and fabrication.
4. Types of MS Fittings
MS fittings are essential for connecting pipes in desired shapes. Some of the most common fittings include:
MS Elbow (45°, 90°, 180°) – Used to change the direction of the pipeline.
MS Tee – Divides or combines the flow into two or three directions.
MS Reducer (Concentric & Eccentric) – Used to connect pipes of different diameters.
MS Coupling – Joins two pipes together.
MS Union – Allows easy disconnection of pipes for maintenance.
MS Flange – Connects pipes with pumps, valves, or other equipment.
MS Nipple – Short length pipe with threads, used in connections.
MS Socket / MS Forged Socket – Connects two pipes at a joint.
MS Cap / Plug – Closes the end of a pipe.
5. Applications of MS Pipe and Fittings
MS pipes and fittings are versatile and used in almost every sector:
Water Supply Systems – For municipal and domestic water distribution.
Construction – For scaffolding, building frames, and structural works.
Plumbing and Drainage – In residential and commercial buildings.
Oil & Gas – For transporting natural gas, petroleum, and other fluids.
Automobile Industry – Used in exhaust systems and chassis.
Firefighting Systems – Essential for hydrant and sprinkler pipelines.
Agriculture – For irrigation pipelines and borewell casings.
Industrial Plants – For steam lines, chemical lines, and machinery connections.
6. Manufacturing Process of MS Pipe and Fittings
The production of MS pipes and fittings involves several steps:
Raw Material Selection – Mild steel coils or billets are chosen.
Forming – Pipes are formed into round or square shapes using rollers.
Welding (ERW) – Electric Resistance Welding for joining the edges.
Heat Treatment – Strengthening the pipe by stress-relieving.
Surface Treatment – Black finishing, galvanization, or epoxy coating.
Fittings Manufacturing – Forging, machining, and welding for elbows, tees, flanges, etc.
Testing & Quality Check – Hydrostatic test, X-ray test, and pressure test.
7. Advantages of Using MS Pipe and Fittings
Long service life with proper maintenance.
Affordable compared to stainless steel or copper.
Suitable for welding, threading, and bending.
Can handle moderate pressure and temperature.
Easily available in different sizes and thicknesses.
Can be coated or galvanized for corrosion protection.
8. MS Pipe and Fittings Price in India
The price of MS pipes and fittings depends on size, thickness, brand, and type. Below is an approximate price range (as of 2025):
MS Pipe Price: ₹50 – ₹90 per kg
MS Elbow Price: ₹20 – ₹200 depending on size
MS Tee Price: ₹30 – ₹250
