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.

| OD (mm) | Bore (mm) | Thickness (mm) | Mass (kg) | |
|---|---|---|---|---|
| 114 | 60 | 16 | 0.945 | |
| 168 | 89 | 18 | 2.296 | |
| 219 | 100 | 20 | 4.77 | |

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.
