ASME Section VIII Div 1 Pressure Vessel Calculator
This calculator determines the required wall thickness for a given internal design pressure, or the Maximum Allowable Working Pressure (MAWP) for a given wall thickness, for cylindrical and spherical shells under internal pressure, based on ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, Part UG-27.
Key Assumptions and Limitations:
- Calculations are for shells under internal pressure only. External pressure calculations are more complex and not included.
- Applies to cylindrical shells with a longitudinal joint and spherical shells (or spherical portions of heads).
- Assumes uniform material properties and temperature.
- This tool is for preliminary assessment and educational purposes. A detailed design must always be conducted by a qualified engineer using the full ASME BPVC code and considering all applicable sections (e.g., impact testing, fatigue, support loads).
Units: Ensure consistency. If you use mm for length, use MPa for pressure and stress. If inches, use psi.
