Flange dimension lookup
Compare selected ASME, EN and JIS flange dimensions. Choose the standard required by the project. The country is carried into the inquiry.
| Flange standard | Pressure class | Nominal size | Outside Ø (mm) | Bolt circle Ø (mm) | Holes × Ø (mm) | Source | Inquiry |
|---|
Nominal sizes are grouped for comparison. Project location only identifies the inquiry market. ASME bolt-hole diameters are converted from inches and rounded to 0.01 mm.
Reference only. Matching dimensions do not establish interchangeability. Confirm the standard edition, flange type, facing, material, service conditions and manufacturer drawing before ordering.
