How to Calculate MS Pipe Price Per Metre (With Weight Chart)

To calculate the MS pipe price per metre, multiply the pipe’s weight per metre (kg) by the rate per kg. A 50 NB Medium pipe weighing 5.03 kg/m at ₹70/kg works out to about ₹352 per metre, before GST, freight and other charges.

This guide explains how to find the weight, convert supplier quotes, and estimate the cost of a full pipe length.

A small change in wall thickness shifts the weight of every metre you buy. Across a large order, that difference can move the budget more than a modest change in the per-kg rate. Weight is where the real cost sits.

How to Calculate MS Pipe Price Per Metre From Weight

Once you know the pipe’s weight per metre and the rate per kilogram, the calculation takes one step.

Formula:
MS pipe price per metre = Weight per metre (kg) × Price per kg (₹)

Example: a 50 NB Medium MS pipe.

The figure of ₹70/kg below is used for illustration only. Actual rates vary by supplier, specification and market conditions.

• Weight per metre: 5.03 kg
• Estimated cost: 5.03 × ₹70 = ₹352.10 per metre

Calculating the Cost of a Full-Length Pipe

MS pipes are typically supplied in lengths between 4 and 7 metres, and 6 metres is a common length for estimating. Confirm the actual supply length with your supplier.

For a 6-metre, 50 NB Medium pipe:

• Total weight: 5.03 × 6 = 30.18 kg
• Estimated material cost: 30.18 × ₹70 = ₹2,112.60

Converting a Per-Tonne Quote to Per Kg

Many suppliers quote steel pipe rates per tonne rather than per kg. To convert, divide the tonne rate by 1,000.

Example: ₹70,000 per tonne ÷ 1,000 = ₹70 per kg

If a quote is given per piece, divide it by the pipe’s length to get a per-metre figure you can compare with other quotes.

How to Calculate MS Pipe Weight Per Metre

If a size isn’t in your chart, you can work out the theoretical weight from the outside diameter (OD) and the wall thickness.

Formula:
Weight (kg/m) = (OD − Wall thickness) × Wall thickness × 0.02466

Both OD and wall thickness are in millimetres. The constant 0.02466 comes from the density of steel (7.85 g/cm³) combined with π.

Example: a 50 NB Medium pipe, with OD 60.3 mm and wall thickness 3.6 mm.

• (60.3 − 3.6) × 3.6 × 0.02466
• = 56.7 × 3.6 × 0.02466
• = 5.03 kg/m

This matches the chart value below, which is useful for checking that a supplier’s weight figure is consistent with the stated dimensions.

MS Pipe Weight Chart (IS 1239 Part 1)

The values below are nominal weights for black (plain-end) ERW steel tubes as per IS 1239 (Part 1). Galvanised or screwed-and-socketed pipes weigh slightly more.

Nominal bore (NB) refers to a nominal pipe size, not the actual diameter. Always check the OD and wall thickness when comparing pipes.

Theoretical vs Actual Weight Billing

The weight chart gives theoretical values. The pipes delivered to your site may weigh slightly more or less, because manufacturing standards allow small tolerances in wall thickness and mass.

This matters because suppliers bill in one of two ways:

• Theoretical weight billing. The number of pipes is multiplied by the chart weight. The invoice matches your estimate closely.
• Actual weight billing. The consignment is weighed, often at a weighbridge, and billed on that weight. The invoice can differ from your chart-based estimate.

Ask which basis the supplier uses before comparing quotes. Two quotes with the same per-kg rate can produce different invoices if one bills on theoretical weight and the other on actual weight.

What Determines the Price of MS Pipes?

Several factors influence the rate per kg and the final cost of an order:

• Pipe diameter. Larger pipes use more steel per metre.
• Wall thickness and class. Within the same nominal bore, Heavy pipes weigh more than Medium or Light pipes.
• Material grade and standard. The specified grade, manufacturing process and applicable standard all affect pricing.
• Finish. Galvanised pipes cost more than black pipes because of the zinc coating and added processing.
• Market rates. Steel and raw material prices change over time.
• Order quantity and delivery. Bulk volumes, transport distance and commercial terms influence the final figure.

What Else to Check Before Buying MS Pipes

The material cost is only part of the purchase budget. Before placing an order, confirm the following:

• Taxes. Check whether GST is included in the quoted rate.
• Freight and loading. These vary with distance and order volume.
• Specifications. Verify the nominal bore, OD, wall thickness, grade and standard.
• Billing basis. Confirm whether billing is on theoretical or actual weight.
• Supply length. Confirm the length of each pipe so your total cost calculation is accurate.
• Commercial terms. Check minimum order quantities, payment terms and how long the quote is valid.

A lower quote is not better value if the pipe is thinner, a different grade, or billed on a different basis. Compare only pipes with matching specifications.

Sourcing MS Pipes From Utkarsh India

Utkarsh India has manufactured steel tubes and pipes in Kolkata for over four decades. It runs one of the largest ERW pipe operations in eastern India, with an annual capacity of 1,40,000 MT across six high-speed tube mills.

The Utkarsh India MS pipes range is made from HR coil sourced from SAIL and TATA. The pipes are produced to IS 1239, IS 3589, IS 1161 and IS 4923. Round pipes are available from 15 mm to 400 mm NB in Light, Medium and Heavy classes. Supply lengths are 4 to 7 metres, with plain, bevelled or threaded ends.

Every batch is tested in the in-house lab before dispatch, including UTM tensile testing and chemical analysis. Utkarsh has supplied MS ERW pipes to projects such as NTPC Kahalgaon, the PGCIL Bhadla substation and the Jal Jeevan Mission drinking water project in Tripura.

Conclusion

Estimating the MS pipe cost comes down to three inputs: weight per metre, rate per kg and supply length. With those, plus a clear understanding of how your supplier bills, you can compare quotes on equal terms. Confirm current rates and specifications with the supplier before finalising the order.

Frequently Asked Questions

1. How do I calculate the MS pipe price per metre?

Multiply the pipe’s weight per metre in kg by the price per kg. For example, a pipe weighing 5.03 kg/m at ₹70/kg costs about ₹352.10 per metre, excluding GST and other charges.

2. What is the standard MS pipe rate per metre?

There is no single standard rate. Pricing depends on size, wall thickness, grade, supplier and current steel prices. Most suppliers quote MS pipe rates per kg or per tonne rather than per metre, so you will usually need to convert the quote using the pipe’s weight.

3. How does MS pipe weight affect its price?

When pipes are priced by weight, a heavier pipe costs more per metre at the same rate per kg. This is why a Heavy class pipe costs more than a Light class pipe of the same nominal bore.

4. Does the MS pipe price include GST and transportation?

Not always. Some quotes show only the basic material rate, while others include certain charges. Confirm GST, freight and loading costs with the supplier.

5. How do I calculate MS pipe weight per metre?

Use the formula: Weight (kg/m) = (OD − Wall thickness) × Wall thickness × 0.02466, with both values in mm. For a pipe with a 60.3 mm OD and 3.6 mm wall thickness, the weight is about 5.03 kg/m.

6. What is the difference between Light, Medium and Heavy MS pipes?

These are wall thickness classes under IS 1239 (Part 1). The outside diameter stays the same for a given nominal bore, but the wall gets thicker from Light to Medium to Heavy. Thicker walls mean more weight per metre and greater strength. Heavy pipes suit higher-pressure or more demanding applications, while Light pipes suit less demanding uses.
