Weight = π/4 × (OD² − ID²) × L × density. Enter OD and wall thickness.
Carbon Steel Pipe Weight (kg/m, OD × wall)
| OD × t | kg/m |
|---|
| DN50 (60.3 × 3.9) | 5.44 |
| DN80 (88.9 × 4.5) | 9.35 |
| DN100 (114.3 × 4.5) | 12.2 |
| DN150 (168.3 × 5.5) | 22.2 |
| DN200 (219.1 × 6.5) | 34.0 |
Formula
Weight (kg/m) = π/4 × (OD² − (OD−2t)²) × ρ × 10⁻⁶ (OD, t in mm)
For steel ρ = 7850 kg/m³
Worked Example
219.1 × 6.5 mm pipe: π/4 × (219.1² − 206.1²) × 7850 × 10⁻⁶ = 34.0 kg/m.
