The Washer Selection Filter node (the WasherSelectionFilter sheet in the Piping Specification.xls workbook) defines selection rules for the washers 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 and the bolt diameter into this selection filter to retrieve the washer commodity code.
Bolt Diameter (Required)
Specify the diameter of the bolt including the unit indicator. For example, type 0.5 in or 2 in.
Specify an optional brief description of the commodity code.
Contractor Commodity Code (Required)
Type the contractor commodity code, which identifies the washer that you want to use from the Washer Part Data Sheet.
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 the washer is intended for in this piping material class. You must specify the maximum temperature if the washer is not intended for the full temperature range of the corresponding piping material class.
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 washer 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 washer selection.
Rating Practice (Optional)
Select the pressure rating practice for the washer selection.
Spec Name (Required)
Type the name of the piping material class for which the washer is intended. The piping materials class that you enter must be defined on the Piping Materials Classes.
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.
Supplementary Washer Requirement (Optional)
Select whether a second supplementary washer is required for each machine bolt or each end of each stud bolt.
Supplementary Washer Contractor Commodity Code (Optional)
Type the contractor commodity code, which identifies the supplementary washer that you want to use from the Washer Part Data Sheet.
Washer Option (Conditionally Required)
Type the washer option code to use when the piping designer does not select a washer type. Valid codes are listed in the AllCodeLists.xls workbook on the WasherOption sheet in the Codelist Number column.
