Wall thickness tables are a reference list of elements with a bore and a wall thickness value. To create a Wall Thickness Table (WTHTAB) the user must first create or navigate to a Table World element (TABWLD) and then select Create > Spec Table > Wall Thickness Table from the main menu bar to display the Create Wall Thickness Table window.

Enter the Name to be assigned to the new Wall Thickness Table and set the Purpose to PIPE.

Click OK to create a Wall Thickness Table in the database hierarchy and display the Wall Thickness Table window.

The Wall Thickness Table builds a set of wall thickness elements (WTHELE) matching the bore sizes in the specification to which it's applied. The user must select a list of bore sizes to match those in the specification from the Available Nominal Bores list.

Click Add to populate the Nominal Bores column. To add the complete Bore list click Add All.

After adding the required Bores, the Remove and Remove All options become active allowing the user to remove Bores from the Nominal Bores list.

After setting the required bores, the Wall Thickness values can be entered.

When all the Wall Thickness values have been entered, click Apply to create the Wall Thickness Table.
