Pipe Weight Calculator | Free Construction Calculators
Calculate the weight of pipe based on material, diameter, and length.
Pipe Material Densities
- PVC (all schedules): 87 lbs/ft³
- Copper: 559 lbs/ft³
- Steel/Iron: 490 lbs/ft³
- Aluminum: 170 lbs/ft³
- Cast Iron: 450 lbs/ft³
Pipe Weight Comparison
| Size | PVC Sch 40 | Copper Type L | Steel Sch 40 |
|---|---|---|---|
| 1/2" | 0.11 lbs/ft | 0.20 lbs/ft | 0.85 lbs/ft |
| 3/4" | 0.14 lbs/ft | 0.36 lbs/ft | 1.13 lbs/ft |
| 1" | 0.19 lbs/ft | 0.46 lbs/ft | 1.68 lbs/ft |
| 2" | 0.42 lbs/ft | 1.14 lbs/ft | 3.65 lbs/ft |
| 4" | 1.0 lbs/ft | N/A | 10.8 lbs/ft |
Schedule Differences
- Schedule 40: Standard wall thickness, most common
- Schedule 80: Thicker walls, higher pressure rating
- Type M Copper: Thinnest wall, residential use
- Type L Copper: Medium wall, commercial/residential
- Type K Copper: Thickest wall, underground
Why Calculate Pipe Weight?
- Structural support: Design hangers and supports
- Shipping costs: Estimate freight charges
- Handling: Plan for equipment needs
- Building loads: Calculate total dead loads
- Material takeoff: Estimate project weight
Support Spacing
PVC Pipe
- Up to 1": 3-4 feet
- 1-1/4" to 2": 4 feet
- 2-1/2" to 3": 5 feet
- Over 3": 5-6 feet
Copper/Steel Pipe
- Up to 1": 6-8 feet
- 1-1/4" to 2": 8-10 feet
- 2-1/2" to 3": 10 feet
- Over 3": 10-12 feet
Important Notes
- Weight calculations don't include water content
- Water adds ~8.3 lbs per gallon to total weight
- Insulation adds additional weight (typically 10-20%)
- Support spacing must account for full pipe weight
- Vertical pipes need supports at every floor
