defined in step 1.
3. To exclude a nominal diameter from the nominal diameter range of the pipe spec, deactivate
the option next to the nominal diameter.
4. To add a nominal diameter to the nominal diameter range of the pipe spec, activate the
option next to the nominal diameter.
5. Click the "Update NDs" button
The nominal diameter range you defined is forwarded to:
– The rest of the tabs in the PipeSpec Designer
– The pipe spec elements

Defining the application limits of the spec

The table for the pressure/temperature rating in the "Class use limit" control group is used for
pipe spec documentation. It is informational in character and independent of the pressure/
temperature rating of the pipe parts.
The values entered here are evaluated on the "Chart" tab and displayed in a diagram.
