MS Pipe Weight Chart 2026 – Kg per Meter, All Sizes + PDF

Last Updated: September 2026

The MS Pipe Weight Chart 2026 provides a convenient reference for calculating the weight of mild steel pipes in kilograms per meter. MS pipes are widely used in water supply, structural fabrication, engineering, construction, industrial piping, agriculture, and infrastructure projects. Knowing the weight per meter helps buyers, engineers, fabricators, contractors, and project planners estimate material quantities, transportation requirements, handling loads, and overall project costs.

MS pipe weight depends mainly on the pipe’s outside diameter (OD), wall thickness, material density, and length. For standard Indian pipe specifications, dimensions and nominal weights are commonly referenced against IS 1239, while BS 1387 is also encountered in traditional pipe specifications. Standard pipe tables classify many sizes into Light, Medium, and Heavy categories, with increasing wall thickness and weight.

The following chart provides commonly referenced MS pipe sizes with Light, Medium, and Heavy classifications. The values are expressed in kg per meter and can be used as a practical reference for estimation.

Nominal Bore	OD (mm)	Light A kg/m	Medium B kg/m	Heavy C kg/m
1/8" (3 NB)	10.32	0.361	0.493	0.593
1/4" (6 NB)	13.49	0.517	0.769	0.859
3/8" (10 NB)	17.10	0.674	0.908	1.061
1/2" (15 NB)	21.43	0.952	1.270	1.450
3/4" (20 NB)	27.20	1.410	1.440	1.900
1" (25 NB)	33.80	2.010	2.580	2.970
1 1/4" (32 NB)	42.90	2.580	3.140	3.840
1 1/2" (40 NB)	48.40	3.250	3.630	4.430
2" (50 NB)	60.30	4.110	5.030	6.170
2 1/2" (65 NB)	76.20	5.840	6.710	8.120
3" (80 NB)	88.90	6.810	8.640	10.100
4" (100 NB)	114.30	9.890	12.110	14.400
5" (125 NB)	139.70	—	16.200	17.980
6" (150 NB)	165.10	—	19.200	21.310

These values are useful for preliminary estimation, but actual supplied weights can vary because of dimensional tolerances, manufacturing conditions, applicable specifications, and whether the pipe is plain-end or supplied with additional components.

How to Calculate MS Pipe Weight Per Meter

A commonly used theoretical formula for calculating the weight of a round MS pipe is:

Weight (kg/m) = 0.02466 × t × (OD − t)

Where:

• OD = Outside Diameter in mm
• t = Wall Thickness in mm
• 0.02466 = constant based on steel density of approximately 7,850 kg/m³

For example, consider a pipe with an OD of 60.3 mm and wall thickness of 3.6 mm:

Weight = 0.02466 × 3.6 × (60.3 − 3.6)

The calculated result is approximately 5.03 kg/m. This corresponds closely with commonly published IS 1239 medium-class values for 50 NB pipe.

This formula is particularly useful when a specific OD and wall thickness are known but a standard weight table is not immediately available.

Light, Medium and Heavy MS Pipe Classes

MS pipes are frequently identified by Light, Medium, and Heavy classifications. The principal difference is wall thickness. For a given nominal size, increasing the wall thickness increases the amount of steel contained in the pipe and therefore increases its weight per meter.

Light pipes generally have thinner walls and lower weight, making them suitable for applications where lower material weight is required.

Medium pipes provide a balance between wall thickness, weight, strength, and cost. They are widely referenced for general industrial and utility applications.

Heavy pipes have thicker walls and higher weights. They may be selected where greater wall thickness is required by the application or specification.

For example, a 100 NB pipe is approximately 9.82 kg/m in Light class, 12.18 kg/m in Medium class, and 14.49 kg/m in Heavy class according to one IS 1239-based calculation table.

MS Pipe Weight Per 6 Meter Length

Once the weight per meter is known, calculating the weight of a complete pipe length is simple:

Pipe Weight = Weight per Meter × Pipe Length

For example, if a 50 NB Medium MS pipe weighs approximately 5.03 kg/m, a 6-meter length would weigh:

5.03 × 6 = 30.18 kg

Similarly, a 100 NB Medium pipe weighing approximately 12.18 kg/m would weigh about 73.08 kg for 6 meters.

This calculation is useful for estimating truck loading, crane handling, storage requirements, and total material tonnage.

Why MS Pipe Weight Is Important

MS pipe weight is an important consideration during procurement and project planning. Engineers use weight charts to prepare bills of materials and estimate the quantity of steel required for fabrication. Procurement teams can compare material requirements against supplier quotations, while logistics teams can estimate transportation loads.

Weight information is also useful when calculating the approximate number of pipes required per tonne. For example, a heavier pipe will provide fewer standard-length pieces per tonne than a lighter pipe of the same nominal diameter.

For large construction and infrastructure projects, even small differences in weight per meter can significantly affect the total material quantity and transportation cost.

Applications of MS Pipes

Mild steel pipes are used across numerous industries because of their versatility, availability, weldability, and suitability for fabrication. Common applications include water pipelines, irrigation systems, structural supports, scaffolding, handrails, agricultural installations, industrial equipment, construction projects, and general engineering work.

The appropriate pipe size and wall thickness should always be selected according to the project design, operating conditions, applicable standards, and engineering requirements.

MS Pipe Weight Chart PDF

A downloadable MS Pipe Weight Chart 2026 PDF can be useful for engineers, fabricators, contractors, traders, and procurement professionals who need quick access to pipe dimensions and weights. A PDF reference can be saved on a computer or mobile device and used while preparing quotations, material estimates, purchase orders, and project documentation.

Before placing an order, buyers should verify the required nominal bore, outside diameter, wall thickness, pipe class, length, applicable standard, and actual manufacturer’s dimensional and weight data. Published theoretical weights should be treated as reference values rather than a substitute for the supplier’s certified product documentation.

Conclusion

The MS Pipe Weight Chart 2026 – Kg per Meter, All Sizes + PDF is a practical resource for estimating the weight of mild steel pipes across different nominal sizes and wall thicknesses. Using the appropriate Light, Medium, or Heavy classification makes it easier to estimate material requirements and project costs.

For accurate procurement, always confirm the pipe dimensions, applicable standard, wall thickness, manufacturing specification, tolerances, and supplied weight with the manufacturer or supplier before finalizing an order.
