You use the Permissible Nominal Piping Diameters Rule node to define what nominal pipe diameters (NPD) are valid for the different piping materials classes. These NPDs appear on the New Pipe Run Dialog in the Nominal Diameter box and are used to create entries in the branch table.

It is your responsibility to make certain that each piping commodity within the piping materials class, each size combination in the Branch Intersection rule, and each tap size in the Permissible Taps rule is consistent with the list of permissible nominal piping diameters defined here. The specific permissible values represented by a size range for a specific piping commodity will be limited to the values specified by the rule that fall within that range.

Nominal Diameter (Required)

Type the nominal pipe diameter that you want available for the piping materials class.

Unit Type (Required)

Specify the units for the nominal pipe diameter value that you entered in the NPD column. For example, type mm or in.

The Permissible Nominal Piping Diameters Rule node in the Catalog task defines the same rules as does the Pipe Nominal Diameters sheet in the workbook. See the Piping Reference Data for information on the Piping workbooks.
