The Pipe Take Down Parts rule (the PipeTakedownParts sheet in the Piping Specification.xls workbook) specifies the short code that the Insert Split command uses for the takedown part or weld. Thus, for a given NPD, the software uses a flange pair, a union, or some other components that enable workers to disassemble a piping system.
Is Pair Required
Specifies if a pair of parts is required. For example, flanges are used in pairs so you would set this column to Yes in Catalog or 1 (true) in the Piping reference data. Unions are not used in pairs so you would set this column to No in Catalog or 0 (false) in the Piping reference data.
Is Weld
In Catalog, select Yes if the split or takedown joint is welded. Select No if it is not. Alternatively, in the Piping reference data type 1 (true) if the split or takedown joint is welded. Type 0 (false) if it is not.
NPD
Type the nominal pipe diameter for which you want to define the takedown or weld short code.
NPD Unit Type
Specify the units for the nominal pipe diameter value that you entered in the NPD column. For example, type mm or in.
Spec Name
Type the name of the piping materials class for which you are defining takedown parts. The piping materials class that you enter must be defined on the Piping Materials Classes.
Take Down Short Code
Specifies the short code to use if the user selects the Takedown option when using the Insert Split command.
Weld Short Code
Specifies the short code to use if the user selects the Weld option when using the Insert Split command.
