The Nut Selection Filter node (the NutSelectionFilter sheet in the Piping Specifications.xls workbook) defines selection rules for the nuts used for bolted joints in the model. You must ensure that the correct material grade is selected to match the recommended bolting temperature and stress ranges. The software passes the piping specification name, bolt type, and bolt diameter into this selection filter to retrieve the nut commodity code and the nut height option from the Nut Part Data.
Specify an optional brief description of the commodity code.
Contractor Commodity Code (Required)
Type the contractor commodity code, which is the code that identifies the nut that you want to use from the Nut Part Data Sheet.
Bolt Type (Required)
Select the bolt type. Valid codes are listed in the AllCodeLists.xls workbook on the BoltType sheet in the Codelist Number column.
Bolt Diameter (Required)
Specify the diameter of the bolt, including the unit indicator. For example, type 0.5 in or 2 in.
Fabrication Category Override (Optional)
Type the fabrication code. Valid codes are listed in the AllCodeLists.xls workbook on the FabricationType sheet in the Codelist Number column.
Maximum Temperature (Conditionally Required)
Specify the maximum temperature that the nut is intended for in this piping material class. You must specify the maximum temperature if the nut is not intended for the full temperature range of the corresponding piping material class.
Nut Option (Conditionally Required)
Type the nut option code to use when the piping designer does not select a nut type. Valid codes are listed in the AllCodeLists.xls workbook on the NutOption sheet in the Codelist Number column.
Piping Note 1 (Optional)
Specify the Standard Notes that you want to associate with the filter. Standard notes are defined in the Piping > Piping Specification > Notes node or on the StandardNotesData sheet in the Piping Specification.xls workbook. If needed, you can customize this sheet to add additional piping note properties. For example, Piping Note 2, Piping Note 3, and Piping Note 4.
Pressure Rating (Optional)
Define the pressure rating for the bolted joint. The software assumes that the nut selection will not vary when the pressure rating values for the two bolted ends are different but the drilling templates are still compatible (for example, Class 125 and Class 150). Therefore, only one pressure rating value is required for nut selection.
Rating Practice (Optional)
Select the pressure rating practice for the nut selection.
Spec Name (Required)
Type the name of the piping material class for which the nut is intended. The piping materials class that you enter must be defined on the Piping Materials Classes.
Supplementary Nut Option (Optional)
Specify another nut option code if a second nut is required for each machine bolt or each end of each stud. Valid codes are listed in the AllCodeLists.xls workbook on the NutOption sheet in the Codelist Number column.
Suppl Nut Cntr Commodity Code (Optional)
Type the contractor commodity code for the supplementary nut. This code identifies the nut that you want to use from the Nut Part Data Sheet.
Supply Responsibility Override (Optional)
Type the supply responsibility code. The supply responsibility code identifies the party responsible for supplying the commodity. Valid codes are listed in the AllCodeLists.xls workbook on the SupplyResponsibility sheet in the Codelist Number column.
