MS Pipe Sizes & Standards (IS 1239)
MS pipes in India are manufactured as per IS 1239 (Part 1 & 2) standards. This standard specifies the nominal bore (NB), outside diameter (OD), and wall thickness for different classes (A, B, C).Common MS Pipe Nominal Bore Sizes:
- 15 NB (½ inch)
- 20 NB (¾ inch)
- 25 NB (1 inch)
- 40 NB (1½ inch)
- 50 NB (2 inch)
- 100 NB (4 inch)
- 150 NB (6 inch)
Each NB size is available in different thickness classes (A, B, C) to suit pressure and application requirements.
MS Pipe Weight Chart (Kg per Meter)
The weight of MS pipes depends on diameter, wall thickness, and class. Below is a reference C Class MS Pipe Weight Chart (IS 1239):
| Nominal Bore (NB) | Outer Diameter (mm) | Thickness (mm) | Weight (Kg/m) |
|---|---|---|---|
| 15 NB (½”) | 21.3 | 3.2 | 1.27 |
| 20 NB (¾”) | 26.9 | 3.2 | 1.68 |
| 25 NB (1”) | 33.7 | 3.6 | 2.41 |
| 40 NB (1½”) | 48.3 | 3.8 | 3.81 |
| 50 NB (2”) | 60.3 | 4.5 | 5.44 |
| 100 NB (4”) | 114.3 | 5.4 | 12.64 |
| 150 NB (6”) | 168.3 | 5.4 | 19.64 |

MS Pipe Classes (A, B, C) Explained
IS 1239 defines three wall-thickness classes:
- Class A (Light): Low thickness, light duty, used in low-pressure applications.
- Class B (Medium): Standard duty, widely used in plumbing & fabrication.
- Class C (Heavy): Thickest walls, used in high-pressure & heavy-duty installations.
