Pressure Vessel Shell Calculator
The Pressure Vessel Shell Calculator finds the required shell thickness and MAWP for a cylindrical vessel per ASME. Example: for a 1000 mm ID cylindrical vessel at 10 bar / 150 °C in SA-516-70, Shell thickness = 5.24 mm, MAWP = 12.08 bar, Outer diameter = 1012 mm (per ASME BPVC Sec. VIII Div.1 | ASME Sec. II Part D | DOLE OSHS PD 856).
How it works
Computed from your inputs per ASME BPVC Sec. VIII Div.1 | ASME Sec. II Part D | DOLE OSHS PD 856.
Worked example (Mechanical & Machine Design)

Computed live by WorkHive's calculation engine; standard: ASME BPVC Sec. VIII Div.1 | ASME Sec. II Part D | DOLE OSHS PD 856.
How to use this calculator
- Enter the figures for the duty you are sizing: the worked example below uses a 1000 mm ID cylindrical vessel at 10 bar / 150 °C in SA-516-70.
- The calculator returns Shell thickness, MAWP, Outer diameter, computed per ASME BPVC Section VIII Div.1.
- Check the worked example to confirm the method matches how you would do it by hand, then run your own numbers in the interactive tool.
FAQ
What is a pressure vessel shell thickness calculator ASME?
The Pressure Vessel Shell Calculator is a free online tool that computes finds the required shell thickness and MAWP for a cylindrical vessel per ASME. It shows the formula and a fully worked example so you can check the method, not just the number.
