This is the documentation page for the Shell & Head Design. You'll find here everything you need to understand how to use our application.
We highly advice you to start by reading the Limitations section, because the version 1.0.0 don't fully support ASME BPVC Section VIII Division 1.
This application support the following types of pressure vessel shell and head:
Shell
Head
The drawings for the head and shell types are generate dynamically and updated every time the USER change a dimension. After the button Run is clicked, the Results page will be shown and the drawing can no longer be changed (unless the user click in the Back button).
All Modules accept two types of units: International and Imperial, but we are working in a way to let the user define his own unit configuration.
The table below shows the units used in each type and can be selected through the System of Units drop down list.
Unit | International | Imperial |
---|---|---|
Temperature | °C | °F |
Pressure | MPa | PSi |
Length | mm | in |
Density | kg/cm3 | lb/in3 |
Volume | m3 | ft3 |
Weight | kg | lb |
Force | N | lbf |
Area | mm2 | in2 |
Moment | N.mm | lbf.in |

The Module will show messages in the results pages when needed.
User that owns the Module can share it with other User by accessing module data in the Project Management page. A complete guide can be found in its Documentation .
Currently there are two types of sharing status:
The version 1.0.0 comes with some limitations which are listed below:
The equations shown in the Results page come mainly from ASME BPVC Section VIII as this Module focus in such standard code. The only equations that didn't come from the Code is the volume and weight, which we used some math and trigonometry to find out.
List of equations that we didn't find in the Code and is used in the Module:
