Many global engineers are accustomed to ASME standards. Key differences: | Feature | EN 12516-1 | ASME B16.34 | |--------|------------|-------------| | Approach | Calculation-based | Pre-calculated tables | | Material groups | European steel grades (1.0619, 1.4408) | ASTM grades | | Safety factor on strength | ~1.5 based on PED | ~3.5 (historical) | | NDT requirements | Integrated via factor z | Separate standards | Any site claiming to offer one is either
The tabulation method provides a quick, standardized approach for sizing, based on: The or Nominal Pipe Size (NPS) . The internal diameter ( Dicap D sub i ) of the inlet bore.
Published by the European Committee for Standardization (CEN), this standard is specifically designed to address the "shell" of a valve—the pressure-retaining boundary that houses the internal components. Whether it is a gate valve, globe valve, or check valve, the body and bonnet must withstand specific pressures and temperatures without rupturing.
While uses a tabulated lookup table for quick design, EN 12516-2:2014+A1:2021 provides the analytical calculation method for steel valve shells. Part 2 is applied for customized, detailed analysis, whereas Part 1 is a rapid design tool. How to Obtain EN 12516-1 PDF (2026 Information)
