Mild steel pipes are widely used for water lines, structural fabrication, industrial piping, engineering projects, fencing, scaffolding, agricultural systems, and general construction. Knowing the weight per meter makes it easier to calculate transportation requirements, project quantities, material costs, and approximate pipe prices.
This updated guide covers MS pipe sizes, Class A, Class B, and Class C pipes, IS 1239 / BS 1387 dimensions, MS pipe weight per metre, weight calculation formulas, large-diameter pipe weights, indicative 2026 MS pipe prices, applications, and a downloadable PDF reference.
Introduction to Mild Steel Pipe
Mild Steel (MS) Pipe is a low-carbon steel tubular product known for its combination of strength, ductility, weldability, machinability, and relatively economical cost. Because mild steel can be fabricated and welded easily, it is commonly selected for general engineering and construction requirements.
Our mild steel pipes are available in different sizes, wall thicknesses, and specifications according to project requirements. MS pipes are also commonly referred to as carbon steel pipes in general industrial terminology.
The carbon content of mild steel is comparatively low, allowing the material to be formed and welded without the fabrication difficulties associated with some higher-carbon steels. Depending on the required application, MS pipes may be supplied as ERW pipes, welded pipes, or other specified configurations.
Typical applications include:
- Water supply and distribution
- Plumbing and utility lines
- Structural fabrication
- Industrial piping
- Agricultural irrigation
- Fencing and railing
- Scaffolding
- HVAC installations
- Machinery and equipment fabrication
- General engineering projects
For buyers, the correct pipe should be selected according to the required diameter, wall thickness, standard, pressure requirement, service conditions, and applicable project specification.
MS Pipe Classification: Class A, Class B, and Class C
MS pipes manufactured to commonly referenced Indian specifications are available in different wall-thickness classes. The three commonly discussed categories are Light Class A, Medium Class B, and Heavy Class C.
The classification affects the amount of steel contained in the pipe and therefore directly affects its weight per meter.
Class A – Light
Class A pipes have comparatively lighter wall thicknesses. They may be selected for applications where lower weight and lower material consumption are important and the service conditions do not require a heavier wall.
Class B – Medium
Class B is a commonly used medium-wall category for general-purpose piping. It provides a balance between pipe weight, mechanical strength, and material cost.
For detailed information, see our MS Pipe Class A, B & C Chart.
Class C – Heavy
Class C pipes have heavier wall thicknesses and consequently higher weight per meter. They are generally selected when additional wall thickness is required for the intended service or project specification.
More information is available in the MS C Class Pipe Thickness Chart.
The actual pipe selection should always be based on the applicable standard, engineering design, operating conditions, and project specifications rather than class alone.
MS Pipe Size and Dimensions
MS pipe dimensions are normally identified using Nominal Bore (NB), outside diameter (OD), and wall thickness.
For weight calculations, outside diameter and wall thickness are especially important. As wall thickness increases while the outside diameter remains constant, the quantity of steel in the pipe increases, and therefore the weight per meter also increases.
Common MS pipe sizes include:
- 15 NB
- 20 NB
- 25 NB
- 32 NB
- 40 NB
- 50 NB
- 65 NB
- 80 NB
- 100 NB
- 125 NB
- 150 NB
Larger-diameter pipes may be supplied according to different specifications and wall-thickness requirements.
For more dimensional information, refer to our MS Pipe Sizes reference.

Why Is the MS Pipe Weight Chart Important?
The MS pipe weight chart in kg helps convert pipe dimensions into practical material quantities. Instead of calculating every pipe individually, users can refer to a standard table to estimate the approximate weight per metre.
The chart is useful for:
- Material estimation—Calculate the approximate quantity of steel required.
- Transportation planning—Estimate the total load for trucks and handling equipment.
- Project costing – Convert required pipe lengths into approximate material weight.
- Procurement—Compare pipe requirements against supplier quotations.
- Fabrication – Estimate the amount of steel entering a fabricated structure.
- Structural calculations – Account for pipe self-weight where required.
- Inventory management – Estimate warehouse stock in tonnes.
- Tender preparation—Prepare approximate material quantities for project BOQs.
For example, if a pipe weighs 14.40 kg/m and the project requires 120 meters:
Total Weight = 14.40 × 120
Total Weight = 1,728 kg
Therefore, approximately 1.728 metric tons of pipe would be required before considering cutting losses, tolerances, or additional procurement allowance.
MS Pipe Weight Formula
The theoretical weight of a circular steel pipe can be calculated using:
Weight (kg/m) = 0.02466 × (OD − t) × t
Where:
- OD = Outside diameter in mm
- t = Wall thickness in mm
- 0.02466 = commonly used constant for steel pipe weight calculation
Example Calculation
Suppose an MS pipe has:
- OD = 114.3 mm
- Wall thickness = 4.5 mm
Then:
Weight = 0.02466 × (114.3 − 4.5) × 4.5
The resulting theoretical weight is approximately 12.18 kg/m.
For an actual purchase, the manufacturer’s published nominal weight should be checked because manufacturing tolerances and the applicable product standard can affect the final supplied weight.
Calculate MS Pipe Weight Online
For faster calculations, use an MS Pipe Weight Calculator by entering the outside diameter, wall thickness, and required length.
Use the MS Pipe Weight Calculator
An online calculator is particularly useful when working with non-standard dimensions, large quantities, or different pipe lengths.
MS Pipe Price Per Kg in India 2026

Recent September 2026 market references show indicative MS/ERW pipe prices in a broad range, with published market examples varying from roughly the high ₹50s to around ₹100/kg depending on product, size, brand, location, and specification.
Indicative MS Pipe Price Table – 2026
| MS Pipe Product | Indicative 2026 Price Range |
|---|---|
| MS Pipe | ₹57–₹72/kg |
| MS ERW Pipe | ₹58–₹75/kg |
| MS Round Pipe | ₹60–₹80/kg |
| MS Structural Pipe | ₹60–₹77/kg |
| Heavy Class MS Pipe | ₹65–₹85/kg |
| Large-Diameter MS Pipe | ₹65–₹95/kg |
These are indicative market ranges, not fixed quotations. Published supplier listings can differ substantially depending on brand, quantity, specification, location, and whether GST and freight are included.
For example, one September 2026 market reference lists MS pipe prices around ₹78–₹101/kg across different sizes and brands, while another published Mumbai listing shows MS ERW pipe at ₹68/kg. These differences demonstrate why buyers should request a size-specific quotation before placing an order.

Important Price Note
MS pipe prices are indicative and can change without notice. Final pricing depends on:
- Pipe size
- Wall thickness
- Class
- Grade
- Brand or manufacturer
- Quantity
- Delivery location
- GST
- Freight
- Testing and certification requirements
- Surface treatment
- Payment and commercial terms
Always confirm the current price before issuing a purchase order.
Relationship Between MS Pipe Weight and Price
MS pipe quotations are commonly provided either per kg or per meter/piece. Understanding pipe weight helps buyers compare these quotation formats.
For example:
Price per meter = Weight per meter × Price per kg
If a pipe weighs 14.40 kg/m and the quoted material rate is ₹70/kg:
14.40 × ₹70 = ₹1,008 per meter
For a 6-meter pipe:
₹1,008 × 6 = ₹6,048 per pipe
This is a simplified material calculation. GST, freight, cutting, testing, coating, and other commercial charges may be additional.
Factors Affecting MS Pipe Weight
Several factors influence the final weight of an MS pipe.
1. Outside Diameter
Increasing the outside diameter generally increases the amount of steel required for a given wall thickness.
2. Wall Thickness
Wall thickness has a direct impact on pipe weight. A heavier-wall pipe contains more steel and therefore weighs more per metre.
3. Pipe Length
Weight per meter remains a dimensional reference, while total pipe weight increases with length.
Total Weight = Weight per meter × Total Length
4. Steel Density
The theoretical calculation uses a standard steel density constant. Actual material chemistry and manufacturing tolerances may result in small variations.
5. Manufacturing Tolerance
Actual supplied dimensions may vary within the tolerances allowed by the applicable specification.
MS Pipe Weight Per Meter vs. Weight Per Piece
One common mistake when purchasing MS pipes is confusing kg/m with kg/piece.
If a pipe weighs 12 kg/m and the standard commercial length is 6 meters:
Weight per piece = 12 × 6 = 72 kg
Therefore:
- Weight per meter = 12 kg
- Length = 6 m
- Approximate weight per pipe = 72 kg
This distinction is important when preparing transportation plans and purchase quantities.
Large Diameter MS Pipe Weight Chart
Large-diameter pipes require separate consideration because their dimensions and applicable specifications can differ from the smaller IS 1239 range.
| Nominal Size | Approx. OD | Wall Thickness | Approx. Weight |
|---|---|---|---|
| 7″ | 193.7 mm | 4.85 mm | 22.59 kg/m |
| 8″ | 219.1 mm | 5.20 mm | 27.45 kg/m |
| 10″ | 273.0 mm | 5.60 mm | 36.85 kg/m |
| 12″ | 323.9 mm | 6.00 mm | 47.06 kg/m |
| 14″ | 355.6 mm | 6.35 mm | 54.65 kg/m |
| 16″ | 406.4 mm | 7.01 mm | 68.99 kg/m |
Note: Large-diameter pipe weight should be verified against the relevant product specification and actual dimensions before commercial use.
How to Select the Correct MS Pipe
