What Is an MS Pipe?
Mild steel pipe is a low-carbon steel tubular product commonly used for construction, fabrication, utility piping, industrial systems, structural work, and engineering applications. Its combination of weldability, ductility, machinability, strength, and relatively economical material cost makes it suitable for many general-purpose applications.
Our Mild Steel Pipes are available in different sizes, wall thicknesses, and specifications according to project requirements.
MS pipes may be supplied in different manufacturing configurations, including ERW and welded pipe products, depending on the required specification and application.
MS Pipe Classes: Class A, Class B, and Class C
MS pipes are commonly discussed in three wall-thickness categories: Class A, Class B, and Class C.
Class A – Light
Class A pipes have comparatively lighter wall thicknesses and lower weight per meter. They may be selected for applications where lower material weight is suitable for the specified service.
Class B – Medium
Class B pipes have medium wall thickness and are commonly used for general-purpose piping and engineering requirements. They provide a balance between material weight, strength, and cost.
For more information, refer to our MS Pipe Class A, B & C Chart.
Class C – Heavy
Class C pipes have heavier wall thicknesses and therefore higher weight per meter. They can be considered when the project specification requires a heavier wall.
See our MS C Class Pipe Thickness Chart for additional reference information.
The appropriate pipe class should always be selected according to the applicable standard, engineering requirements and service conditions.
MS Pipe Sizes and Dimensions
MS pipe dimensions are generally identified using Nominal Bore (NB), Outside Diameter (OD), and Wall Thickness.
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 sizes can also be supplied according to the applicable specification and required wall thickness.
For additional dimensional information, see our MS Pipe Sizes reference.
How to Calculate MS Pipe Weight Per Meter
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 steel pipe weight constant
Example
Suppose:
OD = 114.3 mm
Wall thickness = 4.5 mm
Then:
Weight = 0.02466 × (114.3 − 4.5) × 4.5
The theoretical result is approximately
12.18 kg/m
The calculated result should be compared with the applicable manufacturer’s nominal weight because actual dimensions and manufacturing tolerances can affect supplied weight.
MS Pipe Weight Per Meter vs. Weight Per Piece
The terms “kg/m” and “kg/piece” should not be confused.
If an MS pipe weighs 12 kg/m and the pipe length is 6 meters:
Weight per piece = 12 × 6
Weight per piece = 72 kg
Therefore:
- Weight per meter = 12 kg
- Pipe length = 6 m
- Approximate weight per piece = 72 kg
The total quantity can then be estimated according to the required number of pieces.
For larger projects, the total pipe weight can be calculated using:
Total Weight = Weight per Meter × Total Length
For example, if the pipe weighs 14.40 kg/m and the required length is 120 meters:
14.40 × 120 = 1,728 kg
Therefore, the estimated material weight is 1.728 metric tonnes, before considering cutting losses, tolerances or additional procurement allowance.
MS Pipe Weight Calculator
An online MS Pipe Weight Calculator can make theoretical weight calculations faster.
Users can enter the outside diameter, wall thickness, and required length to estimate the pipe’s total weight.
A calculator is particularly useful when working with:
- Different pipe sizes
- Non-standard dimensions
- Large quantities
- Different pipe lengths
- Project material estimates
- Transportation planning
For final procurement, the calculated value should always be checked against the applicable standard and manufacturer’s published nominal weight.
MS Pipe Price Per Kg in India 2026
The price of MS pipe varies according to the steel market, pipe size, wall thickness, class, manufacturer, brand, quantity, delivery location, GST, freight, and testing requirements.

For more information, visit our MS Pipe Price page.
How Weight Affects MS Pipe Price
When the quotation is provided on a per-kilogram basis, pipe weight can be used to estimate the approximate price per meter.
Price per meter = Weight per meter × Price per kg
For example:
14.40 kg/m × ₹70/kg = ₹1,008 per meter
For a 6-meter pipe:
₹1,008 × 6 = ₹6,048 per pipe
This is only a material-cost calculation. GST, freight, testing, cutting, coating and other applicable charges may be additional.
Factors That Affect MS Pipe Weight
Several factors influence the weight of an MS pipe.
1. Outside Diameter
A larger outside diameter generally increases the quantity of steel used for a given wall thickness.
2. Wall Thickness
Wall thickness has a direct effect on weight. Increasing thickness increases the amount of steel in the pipe and therefore increases kg per meter.
3. Length
Weight per meter is a dimensional reference, while total weight depends on the complete pipe length.
Total Weight = Weight per Meter × Total Length
4. Steel Density
The theoretical formula uses a standard density-based constant. Small differences can occur because of material composition and manufacturing tolerances.
5. Manufacturing Tolerance
Actual dimensions may vary within the tolerances permitted by the relevant product specification.
Large Diameter MS Pipe Weight
Large-diameter MS pipes require separate consideration because their dimensions and applicable manufacturing specifications may differ from commonly listed smaller pipe sizes.

Why the MS Pipe Weight Chart Is Important
The MS Pipe Weight Chart 2026 provides a convenient way to convert pipe dimensions into practical material quantities. Instead of calculating each pipe individually, buyers can refer to the chart to estimate approximate kg per meter.
The chart can help with:
- Material estimation
- Project quantity calculations
- Transportation planning
- Procurement
- Cost estimation
- Fabrication planning
- Inventory management
- Tender and BOQ preparation
- Warehouse stock estimation
- Logistics planning
For example, knowing the kg/m value allows a procurement team to estimate the approximate total tonnage required for a project before requesting a quotation.
