Quick Answer

👉 Basic formula:

Weight = π × (OD² − ID²) / 4 × Length × Density × Quantity

  • OD = Outer Diameter
  • ID = Inner Diameter
  • Length = Pipe length
  • Density = Material density

✔ Example (steel pipe):
OD 50 mm, ID 40 mm, Length 1000 mm
→ Weight ≈ 5.42 kg

Formula (Pipe Weight Calculation)

Standard Engineering Formula:

Weight (kg) = π × (OD² − ID²) / 4 × L × Density × Quantity ÷ 1,000,000

(when: OD & ID in mm, density in g/cm³)

Common Material Density (Reference)

Material Density (g/cm³)
Aluminum 6061 2.70
Aluminum 7075 2.81
Carbon Steel 7.85
Stainless Steel 7.93–8.00
Titanium Grade 5 4.43
Brass 8.50
Copper 8.96

Pipe Weight Reference Table

(Carbon Steel, Density = 7.85 g/cm³, Length = 1 meter)

OD (mm) ID (mm) Weight (kg/m)
50 40 5.42
60 50 6.77
80 70 9.12
100 80 18.84
150 120 41.55

How to Use This Calculator

  1. Select a material (auto-fills density)
  2. Enter outer diameter (OD)
  3. Enter inner diameter (ID)
  4. Input length (mm)
  5. Enter quantity (pcs)
  6. Get instant total weight (kg)

✔ Real-time calculation
✔ Ideal for engineering and procurement

Common Engineering Uses

1. Piping System Design

  • Calculate pipe weight for structural support and load analysis

2. CNC Machining & Fabrication

  • Estimate raw material weight before machining

3. Material Procurement

  • Determine total material requirements

4. Shipping & Logistics

  • Estimate freight cost based on total weight

Important Notes

  • Ensure OD > ID, otherwise calculation is invalid
  • Density may vary depending on alloy and condition
  • Units must be consistent (mm + g/cm³ recommended)

FAQ

How do you calculate pipe weight?

Use:
👉 Weight = π × (OD² − ID²) / 4 × Length × Density

What happens if OD equals ID?

The pipe has zero thickness, so weight = 0.

Can I use this for all materials?

Yes, as long as you input the correct density.

What unit is the result in?

Typically kilograms (kg).

Can I calculate in inches?

This calculator is optimized for mm, but can be converted if needed.
