The Weld Gap Rule node (the WeldGapRule sheet in the Piping.xls workbook) specifies the space between male welded ends of a welded joint when space is required by the welding process. The weld gap is used to compute the piping cut lengths and to provide accurate modeling of fitting-to-fitting pipe spools.
Nominal Diameter From (Optional)
Define the lower bound of the largest nominal piping diameter for which this weld gap applies.
Nominal Diameter To (Optional)
Define the upper bound of the largest nominal piping diameter for which this weld gap applies.
Nominal Piping Diameter Units (Optional)
Specify the units for the Nominal Diameter From and Nominal Diameter To columns. For example, type in for inches or mm for millimeters.
Spec Name (Required)
Type the name of the piping material class for which you are defining weld gaps. The piping materials class that you enter must be defined on the Piping Materials Classes.
Weld Gap (Required)
Type the gap between the welded ends of the welded joint. Be sure to include the units when defining this value, for example, 3mm.
Weld Type (Required)
Enter the weld type code. Valid codes are listed in the AllCodeLists.xls workbook on the WeldType sheet in the Codelist Number column.
