MS Pipe Weight Chart – Round & Square Pipe Weight Per Meter
Introduction: Why MS Pipe Weight Matters
MS (Mild Steel) pipes are an essential component in structural, industrial, and civil engineering applications. One of the most important parameters to consider while choosing an MS pipe is its weight per meter. Whether you're estimating loads for fabrication, purchasing raw materials, or planning logistics for site delivery, accurate MS pipe weight calculations are crucial.
This article offers a complete MS pipe weight chart for both round and square pipes, covering all standard sizes and thicknesses as per IS 1239. It also explains weight calculation formulas, provides a downloadable PDF chart, and compares weight variation by pipe shape and wall class (A/B/C).
MS Pipe Standards Used for Weight Reference
| Standard Code | Description |
|---|---|
| IS 1239 (Part 1) | For steel tubes used in water lines, gas lines, air, and steam |
| IS 3589 | For large diameter pipes used in fluid transmission |
| Class A / B / C | Light, Medium, and Heavy thickness categories |
MS Round Pipe Weight Chart (Per Meter)
| NB Size (mm) | OD (mm) | Thickness (mm) | Weight per Meter (kg) | Class |
|---|---|---|---|---|
| 15 | 21.3 | 2.65 | 1.25 | B |
| 25 | 33.7 | 3.25 | 2.47 | B |
| 40 | 48.3 | 3.25 | 3.52 | B |
| 50 | 60.3 | 3.65 | 5.44 | C |
| 80 | 88.9 | 4.05 | 9.83 | C |
| 100 | 114.3 | 4.5 | 12.95 | C |
Note: Weights are approximate based on IS 1239.
MS Square Pipe Weight Chart (Per Meter)
| Size (mm x mm) | Thickness (mm) | Weight/meter (kg) |
|---|---|---|
| 25 x 25 | 2.0 | 1.47 |
| 40 x 40 | 2.5 | 3.14 |
| 50 x 50 | 3.0 | 4.89 |
| 75 x 75 | 3.0 | 7.47 |
| 100 x 100 | 4.0 | 12.55 |
How to Calculate MS Pipe Weight – Formula
Weight (kg/m) = (OD – WT) × WT × 0.02466
Example: For 60.3 mm OD and 3.65 mm thickness: Weight = (60.3 – 3.65) × 3.65 × 0.02466 = ~5.44 kg/m
Class-Wise MS Pipe Weight Differences
| Class | Thickness Range | Weight Impact | Use Case |
|---|---|---|---|
| Class A | 2.0–2.5 mm | Lightest | Plumbing, scaffoldings |
| Class B | 2.65–3.25 mm | Medium | Water pipelines, fencing |
| Class C | 3.65–5.40 mm | Heaviest | High-pressure and load-bearing |
Round vs Square vs Rectangular Pipe Weights
| Type | Weight Range (kg/m) | Used In |
|---|---|---|
| Round | 1.25–50+ | Water, gas, structure |
| Square | 1.5–30 | Railing, frames, gates |
| Rectangular | 2.0–40 | Panels, roofing, sheds |

HSN Code & Specification Reference
- HSN Code for MS Pipe: 730630
- IS Specification: IS 1239 Part 1 for small bore pipes, IS 3589 for large bore
- Standard Length: 6 meters
- Material: Mild steel, low carbon (0.1%–0.2%)
MS Pipe Weight & Pricing
MS pipe pricing is directly proportional to weight per meter. If you know the weight, you can easily calculate cost:
Cost = Weight × Rate per KG
Example: Weight = 5.44 kg/m, Rate = ₹70/kg → Price/meter = ₹380.8
Applications Where Pipe Weight is Critical
- Steel structures
- Scaffolding and supports
- Fire hydrant & water lines
- Industrial fabrication
- Agricultural irrigation
- Pressure pipelines
- Fencing & railing

Frequently Asked Questions (FAQ)
- Q1. What is the standard weight of 1-inch MS pipe?
- A: A 25 mm (1 inch) MS pipe with 3.25 mm wall thickness weighs approx. 2.47 kg per meter.
- Q2. How much does a 6-meter MS pipe weigh?
- A: Multiply weight/meter by 6. For example, a 60.3 mm OD pipe with 3.65 mm thickness weighs 5.44 × 6 = 32.64 kg.
- Q3. Which class pipe weighs more?
- A: Class C pipes have the highest wall thickness and therefore the highest weight.
- Q4. Can I use square MS pipe for water lines?
- A: Technically yes, but round pipes are recommended for pressure and flow efficiency.
