Pipe Weight Formula
Weight (kg) = [(OD - t) × t × π × Length × Density] ÷ 1000
Where:
- OD: Outer Diameter (mm)
- t: Wall Thickness (mm)
- Length: Pipe length (m or mm)
- Density: Material density (g/cm³)
Common Metal Material Density Reference
| Material | Density (g/cm³) | Note |
|---|---|---|
| Carbon Steel | 7.85 | Q235, 20# Steel |
| Stainless Steel | 7.93 | 304, 316 |
| Aluminum | 2.70 | Pure Aluminum, Alloy |
| Copper | 8.90 | Red Brass, Yellow Brass |
