Standards & codes
Reference information
Commonly cited families (verify edition on your certificate):
- EN 1092-1
- ASME B16.5/B16.47
- GOST 12815
- GOST 12821
Pipe flanges are dimensioned in EN 1092-1 (European), ASME B16.5/B16.47 (US), and GOST 12815 / 12821 series for Russian flanged joints. Forged blank mass differs from final machined mass once bolt holes, grooves, and facing are applied.

Illustrative values for common sizes of Flange at the density you selected. For procurement, always verify against mill certificates.
| OD (mm) | Bore (mm) | Thickness (mm) | Mass (kg) | |
|---|---|---|---|---|
| 114 | 60 | 16 | 0.319 | |
| 168 | 89 | 18 | 0.775 | |
| 219 | 100 | 20 | 1.61 | |
| 273 | 150 | 22 | 2.427 |
Figures follow the same geometric model as the calculator above; rounding and simplifications apply.
Method
How to calculate weight
Core model
V = π · ((D/2)² − (d_bore/2)²) · t
m = ρ · VField names
A blind/forged flange blank is approximated as an annulus (outer diameter, bore, axial thickness). Useful for quick blank-weight estimates before machining; compare with EN 1092-1 / ASME B16.5 mass tables for procurement.
There is no bar “length” field—use forward mode only.
