Pipe Weight Calculator
Calculate pipe weight per meter and total weight for any NPS size and schedule. Supports carbon steel, stainless steel, and custom materials.
How to Calculate Pipe Weight
Pipe weight is calculated using the cylindrical shell formula. The weight depends on the outside diameter (OD), wall thickness (t), length, and material density.
Formula
W = (OD - t) × t × 0.02466 × LExample Calculation
For a 6" SCH 40 carbon steel pipe, 12 meters long:
- OD = 168.3 mm
- Wall thickness (SCH 40) = 7.11 mm
- Length = 12 m
- Density = 7850 kg/m³
Result: ~28.3 kg per meter, ~339.6 kg total for 12 meters.
Common Pipe Schedules
| Schedule | Description |
|---|---|
| STD | Standard - same as SCH 40 for NPS ≤ 10" |
| XS | Extra Strong - same as SCH 80 for NPS ≤ 8" |
| XXS | Double Extra Strong |
| SCH 10 / 20 / 30 | Light wall schedules |
| SCH 40 / 60 / 80 / 100 / 120 / 140 / 160 | Heavy wall schedules |
Frequently Asked Questions
What is the difference between STD, XS, and SCH 40?
For NPS 1/8" through 10", STD (Standard) has the same wall thickness as SCH 40. For NPS 12" and larger, STD wall is thinner than SCH 40. XS (Extra Strong) equals SCH 80 for NPS 8" and smaller, but is thicker than SCH 80 for larger sizes.
How accurate is this pipe weight calculator?
This calculator uses the exact ASME B36.10M dimensions and the theoretical formula. Actual weight may vary slightly due to manufacturing tolerances (typically ±5-10%). Always verify critical weights with actual measurements for shipping and structural calculations.
What is the density of carbon steel pipe?
Standard carbon steel (A106, A53, A105) has a density of approximately 7850 kg/m³ (0.284 lb/in³). Stainless steel 304 is about 8000 kg/m³, and stainless 316 is about 7980 kg/m³.
Can I calculate weight for custom materials?
Yes. Select "Custom Density" from the material dropdown and enter your material's density in kg/m³. This is useful for alloy steels, aluminum, copper, or plastic pipes.
