PN vs. Class Cross-Reference Tool
The shorthand “PN16 ≈ Class 150” is only correct at 20°C for one material group — and wrong for bolt circle compatibility. Select a PN rating and ASME Class to see the actual pressure, dimensional, and documentation differences.
EN 1092-1

| Comparison Point | EN 1092-1 (PN) | ASME B16.5 (Class) | Direct Substitute? |
