Configuring pipe specs
8.3 Configuring the "Characteristics" tab
formula "CatPC". In this case, the pipe spec element uses the local dimensions of the pipe
spec and the table is purely informational in character.
Note
● Do not configure the table until you have finished defining the nominal diameter range on
the "PipeSpec limits" tab.
Reason: Clicking on the "Update NDs" button to forward new values can mix up the
assignment between nominal diameters and other parameters.
● Do not configure the "Nominal diameter" row manually.
Reason: The "Nominal diameter" row must always show the nominal diameter range
defined on the "Application limits" tab.
When you click the "Update NDs" button on the "Application limits" tab, the current nominal
diameter range is written to the characteristic-dependent table. This can mix up the
assignment between nominal diameters and the other characteristics.
Requirement
● Observing the workflow for configuration of pipe specs. See also chapter Overview for
configuring pipe specs (Page 79).
● You have opened the "Characteristics" tab.
Procedure
Enter the characteristics depending on the nominal diameter.
You have two options when configuring the "Outside diameter" and "Wall thickness" rows:
● Take the values from a geometry table. To do this, set a reference to a geometry table on
the "Application limits" tab and specify a row.
● Enter the outer diameter for the pipe spec members manually.
When you set a reference to a geometry table in the "Application limits" tab and specify a
row, your entries are overwritten.
