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

Last Updated: October 2026

An MS Pipe Weight Chart 2026 helps buyers, engineers, contractors, fabricators, and project planners understand how much a mild steel pipe weighs according to its diameter and wall thickness. Pipe weight is important when calculating material requirements, transportation loads, structural quantities, fabrication costs, and overall project budgets.

Mild steel pipes are available in different nominal sizes, outside diameters, wall thicknesses, and classes. Because these dimensions directly influence the amount of steel used, two pipes having the same nominal bore can have different weights. This is why checking the MS pipe weight per meter is useful before purchasing or estimating material.

MS Pipe Weight in Kg per Meter

MS pipe weight is normally expressed as kilograms per meter (kg/m). The kg/m value represents the approximate weight of one meter of pipe. To determine the weight of a complete pipe, the kg/m value is multiplied by its actual length.

For example, if an MS pipe weighs 12 kg/m and the required pipe length is 6 meters:

12 × 6 = 72 kg

Therefore, one 6-meter pipe would weigh approximately 72 kg.

The actual supplied weight can differ slightly from a theoretical calculation because of manufacturing tolerances, dimensional variations, and the applicable product specification.

What Determines MS Pipe Weight?

The weight of an MS pipe is mainly influenced by four dimensions and characteristics: outside diameter, wall thickness, length, and material density.

A larger outside diameter generally requires more steel. Similarly, increasing the wall thickness increases the amount of metal contained in the pipe and therefore raises its weight per meter.

Length does not change the kg/m value, but it directly affects the total weight of the pipe. For bulk orders, the total weight can be estimated by multiplying the pipe's weight per meter by the combined length required.

MS Pipe Class A, B and C

MS pipes are commonly identified according to different wall-thickness categories. Class A, Class B, and Class C are frequently used references when discussing light, medium, and heavy pipe configurations.

Class A MS Pipe

Class A represents a lighter wall configuration. Since less steel is used in the pipe wall, its kg/m value is comparatively lower. This type may be suitable for applications where the specified service conditions permit a lighter wall.

Class B MS Pipe

Class B represents a medium wall configuration. It provides a higher weight per meter than the lighter class and is commonly considered for general-purpose engineering and piping requirements.

Class C MS Pipe

Class C represents a heavier wall configuration. The additional wall thickness increases the amount of steel and therefore produces a higher kg/m value.

The appropriate class should always be selected according to the applicable standard and project requirements rather than weight alone.

MS Pipe Weight Calculation Formula

A commonly used theoretical formula for calculating the weight of a circular steel pipe is:

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

Where:

• OD = Outside diameter in mm

• t = Wall thickness in mm

• 0.02466 = commonly used calculation constant

Example Calculation

Consider an MS pipe with:

Outside Diameter = 114.3 mm
Wall Thickness = 4.5 mm

Using the formula:

Weight = 0.02466 × (114.3 − 4.5) × 4.5

The theoretical weight is approximately:

12.18 kg/m

This figure is useful for estimation, but the manufacturer's nominal weight should be checked before final commercial or engineering use.

MS Pipe Weight Per Meter vs Per Piece

One of the most common mistakes in material estimation is confusing weight per meter with the weight of an entire pipe.

Suppose a pipe weighs 14.40 kg/m and each pipe is supplied in a 6-meter length.

14.40 × 6 = 86.40 kg

The approximate weight of one 6-meter pipe is therefore 86.40 kg.

If 100 such pipes are required:

86.40 × 100 = 8,640 kg

This equals approximately 8.64 metric tonnes.

This calculation can help purchasing teams estimate total material tonnage before requesting quotations.

MS Pipe Weight for Different Sizes

MS pipes are identified using nominal bore along with outside diameter and wall thickness. Common commercial sizes include 15 NB, 20 NB, 25 NB, 32 NB, 40 NB, 50 NB, 65 NB, 80 NB, 100 NB, 125 NB, and 150 NB.

The weight of each size changes according to the selected wall thickness. For instance, a 2-inch pipe with a 60.3 mm outside diameter can have substantially different kg/m values depending on whether a lighter, medium, or heavier wall is selected.

Similarly, a 4-inch pipe with approximately 114.3 mm OD may have a weight around 9.89 kg/m for a lighter configuration, 12.11 kg/m for a medium configuration, and 14.40 kg/m for a heavier configuration.

For larger sizes, the same principle applies: greater diameter and wall thickness generally result in higher weight.

Large-Diameter MS Pipe Weight

Large-diameter MS pipes are used in infrastructure, industrial projects, fabrication, utility systems, and other applications where larger flow or structural dimensions are required.

Approximate reference values include:

• 7-inch pipe: around 22.59 kg/m

• 8-inch pipe: around 27.45 kg/m

• 10-inch pipe: around 36.85 kg/m

• 12-inch pipe: around 47.06 kg/m

• 14-inch pipe: around 54.65 kg/m

• 16-inch pipe: around 68.99 kg/m

These values should be treated as reference figures. The actual weight depends on the supplied dimensions and applicable specification.

How to Calculate Total MS Pipe Weight

For project estimation, the following simple calculation can be used:

Total Pipe Weight = Weight per Meter × Total Pipe Length

For example, if the selected pipe weighs 18 kg/m and the project requires 500 meters:

18 × 500 = 9,000 kg

Therefore, the estimated requirement is 9 metric tonnes.

For large projects, this calculation can help with procurement planning, storage requirements, transportation arrangements, and preliminary budgeting.

MS Pipe Price Per Kg in 2026

MS pipe prices change according to raw material rates, pipe size, wall thickness, manufacturing process, supplier, quantity, location, freight, taxes, testing, and other commercial conditions.

Indicative 2026 market references may place common MS pipe products in different price ranges, while heavy-wall and large-diameter products can command higher rates.

A quotation based on the exact specification is more useful than relying on a general market rate. Buyers should provide the required size, thickness, class, quantity, length, standard, and delivery location when requesting a price.

The relationship between weight and price can be calculated as:

Price per Meter = Weight per Meter × Price per Kg

For example, a pipe weighing 14.40 kg/m at a material rate of ₹70/kg would have an estimated material value of:

14.40 × ₹70 = ₹1,008 per meter

This is only a basic material calculation and does not include additional commercial charges.

Why MS Pipe Weight Calculation Is Important

Accurate weight estimation has several practical benefits. It helps determine how much material is required for a project and provides a basis for calculating transportation and handling requirements.

Weight information can also assist with:

• Preparing material estimates

• Creating project BOQs

• Comparing supplier quotations

• Calculating approximate material costs

• Planning warehouse capacity

• Estimating transportation loads

• Preparing procurement schedules

• Managing inventory

• Calculating project tonnage

• Planning fabrication quantities

For contractors and fabricators, having the correct kg/m value can reduce errors when converting between pipe lengths, pieces, and total tonnage.

Applications of MS Pipes

MS pipes are used in a wide range of engineering and construction applications. Common uses include structural frameworks, railings, scaffolding, fencing, water systems, agricultural irrigation, industrial utility lines, equipment supports, fabrication projects, infrastructure structures, and general engineering work.

Their weldability and ease of fabrication make them practical for applications where pipes need to be cut, joined, welded, drilled, or assembled into larger structures.

However, mild steel can require suitable corrosion protection in environments where moisture, chemicals, salt, or other corrosive conditions are present.

How to Choose the Correct MS Pipe

Selecting an MS pipe should involve more than checking the weight. First identify the required nominal size and outside diameter. Next determine the necessary wall thickness and pipe class.

The applicable specification should then be confirmed, followed by the required pipe length, quantity, testing requirements, and delivery conditions.

Before placing an order, buyers should verify:

• Nominal bore

• Outside diameter

• Wall thickness

• Pipe class

• Applicable standard

• Material specification

• Required length

• Quantity

• Testing requirements

• Delivery location

• Current quotation

This ensures that the selected pipe matches the technical and commercial requirements of the project.
