Flange Weight Calculator
Estimate the weight of a flange from its outside diameter, bore, thickness, hub and bolt holes — useful for costing, freight and lifting checks.
- Weight per flange
- 10.16 kg
- Total (1 pcs)
- 10.16 kg
- Total in tonnes
- 0.010 MT
- Material volume
- 1,294.4 cm³
Formula used
V = π/4 × (OD² − B²) × t + π/4 × (Dhub² − B²) × h − n × π/4 × d² × t
All dimensions in millimetres; weight W = V × ρ × 10⁻⁹ with density ρ in kg/m³. Leave the hub fields at zero for a plate or blind-style flange without a hub.
This is a geometric approximation: raised faces, tapered hubs, chamfers and machining allowances mean the actual flange weight will differ slightly from the calculated figure.
Results are theoretical calculations based on the values you enter. Actual weights and quantities vary with manufacturing tolerances. Confirm requirements with our team before ordering.
