Tutorial for the test pressure calculation with PED Professional

To start the test pressure calculation, click on the symbol "Test pressure" in the toolbar or in the left quick start menu under the register "Tools"

in the software PED.

Please enter the general data about the project, as the project name and optional description.

Now the design data like wall thickness, temperature and pressure are entered

Project data

Design data

Wall thickness emin in mm: minimum wall thickness of the component.

Design temp. TS in °C: Maximum allowable temperature in °C.Max. allowable pressure Ps in bar: Maximal allowable pressure of the equipment.

Design pressure Pd at Td in bar: Design pressure Pd in bar at design temperature Td

The values are shown in the drawings.

In the next section, you can either enter a material and select the appropriate material type from the list or choose a material with the associated parameters from

the PED Professional material database. If you configured a special database connection for your material database the settings could be entered by clicking on

"Configure database". In all other cases, the default database is used

After the selection of a material from the database, the material type is automatically determined. You can change these proposals at any time or enter

them completely by hand.

List of materials

The type of material is crucial for determining the calculation.

Choose the testing group of your pressure equipment. Click on help to get additional information.

Choose your material group, if your pressure equipment belongs to testing group 4. Enter the corrosion allowance if needed.

Formulas for calculating the design strengths and the test pressure. The correct formulas will be shown after choosing the material type (3) and the

material and testing group (4).

The values for the tensile strength (Rm) and for the proof strength (Rp) are filled after choosing a material from the database or could be manually

filled in. After every change the test pressure is calculated.

Parameters relevant to the calculation are highlighted in blue.
