Comparison with Other Standards
EN 10216-2 is a direct European equivalent to other well-known pressure tube standards:
| Feature | EN 10216-2 | ASTM A106 | ASTM A335 |
|---|---|---|---|
| Region | European Union | USA / International | USA / International |
| Process | Seamless | Seamless | Seamless |
| Service | Pressure, Elevated Temp | Pressure, Elevated Temp | High-Temperature Service |
| Common Grades | P235GH, P265GH, 16Mo3 | Grade A, B, C | P5, P9, P11, P22, P91 |
| Key Difference | Comprehensive elevated temp data, PED compliance. | Focuses on room temp and basic elevated temp props. | Specifically for ferritic alloy steels for high-temp. |
Note: While the grades are different, there are "similar" or "equivalent" grades across these standards (e.g., 16Mo3 is similar to A335 P12, and P265GH is similar to A106 Grade B).
