The Clamp Selection Filter node (the ClampSelectionFilter sheet in the Victaulic Spec A4.xls and Victaulic Spec A11 workbooks) defines selection rules for clamps used for mechanical joints in the model.

The Termination Subclass property of the End Preparation is used to determine whether the clamp selection filter is used to select a clamp. Clamps are required when the Termination Subclass property is "Mechanical Joint with Clamp" (50) or "Mechanical Joint with Clamp and Hub or Ferrule" (55).

Clamps and Gaskets

Some clamps also require either a seal ring or a gasket between the mechanical ends. If the seal ring or the gasket is to be reported independently of the clamp, the clamp part must indicate that in the Gasket Requirement option in the Piping Commodity Material Control Data to select the gasket from the gasket selection filter.

The Gasket Requirement option also indicates whether the gasket is to be selected on the basis of the hub’s schedule, as in the cases of Grayloc®, SPO-Lock, and Techlok types of clamps, or the gasket thickness is not a function of the combination of the hub and gasket, as in the case of the Tri-Clamp type of clamp.

The seal ring or the gasket is inserted automatically for any clamp at a mechanical joint, where the Gasket Requirement option in the Piping Commodity Material Control Data for the clamp indicates that a gasket is required. The maximum temperature, pressure rating, and fluid code are not required when selecting a gasket for a mechanical joint from the gasket selection filter. Conversely, the schedule is only required when selecting a gasket for a mechanical joint, which involves hub ends. However, the schedule is not required for selecting a gasket at a mechanical joint based on ferrule ends.

Clamps and the Automatic Insertion of Hubs

If you insert a mechanical hub; such as Techlok, Grayloc®, or SPO-Lock; or insert a fitting with Techlok-type, Grayloc®-type, or SPO-Lock- type hub ends and continue routing pipe stock, then a second matching hub is automatically inserted when the End Preparation's Termination Subclass property is "Mechanical Joint with Clamp and Hub or Ferrule" (55).

However, before the second hub is inserted automatically, a clamp must be selected based on the two mechanical ends. In the case of Techlok, Grayloc®, and SPO-Lock fittings, the clamp indicates (by means of the Gasket Requirement option of the Piping Commodity Material Control Data) that a seal ring (gasket) is required. The seal ring is determined based on the properties of the hub. The second hub is then inserted and spaced by the applicable gasket gap. Therefore, when you insert a single mechanical hub, or a fitting with hub ends, a second mechanical hub, a clamp, and a seal ring are inserted automatically.

Clamps and the Automatic Insertion of a Ferrule

If you insert a mechanical ferrule, such as a Tri-Clamp, or insert a fitting with male ferrule ends and continue routing pipe stock, then a second matching ferrule is automatically inserted when the End Preparation's Termination Subclass property is "Mechanical Joint with Clamp and Hub or Ferrule" (55).

However, before the second ferrule is inserted automatically, a clamp must be selected based on the two mechanical ends. In the case of Tri-Clamp fittings, the clamp indicates (by means of the Gasket Requirement option of the Piping Commodity Material Control Data) that a rubber-like gasket is required. Unlike the seal ring for Grayloc®, SPO-Lock, and Techlok fittings, the gasket is not based on the properties of the ferrule. The second ferrule is then inserted and spaced by the applicable gasket gap. Therefore, when you insert a single mechanical ferrule, or a fitting with male ferrule ends, a second mechanical ferrule, a clamp, and a gasket are inserted automatically.

If you define any records using this rule, the software only uses this spec break rule to check for the connection parts at the spec break condition. You must define all the possible combinations or records that can be encountered in the model for the spec break condition. If at least one entry is defined in the rule, then the software does not check for the connection parts in the selection filters as it would in the default behavior.

Alternate End Preparation (Conditionally Required)

Type the end preparation code for the other end when a second end preparation applies to the mechanical joint. For example, small-grove-face lap-flanged end. Valid codes are listed in the AllCodeLists.xls workbook on the EndPreparation sheet in the Codelist Number column.

Alternate End Standard (Conditionally Required)

Type the other end standard code when a second end standard applies to the mechanical joint. Valid codes are listed in the AllCodeLists.xls workbook on the EndStandard sheet in the Codelist Number column.

Alternate Pressure Rating (Conditionally Required)

Type the other pressure rating code when a second pressure rating applies to the mechanical joint. Valid codes are listed in the AllCodeLists.xls workbook on the PressureRating sheet in the Codelist Number column.

Alt Reportable Commodity Code (Optional)

Specify the contractor commodity code for an alternate reportable piping commodity that is to be created with the primary piping commodity on the basis of the piping materials class. In an isometric drawing, only the primary piping commodity is depicted graphically. The materials list includes the short description of both the primary piping commodity and the reportable piping commodity. The data for the reportable piping commodity includes a commodity code and the corresponding short and long material descriptions, plus the typical data that is reported for any other piping commodity.

Clamp Option (Conditionally Required)

Type the clamp option code to use when the piping designer does not select a clamp type. Valid codes are listed in the AllCodeLists.xls workbook on the ClampOption sheet in the Codelist Number column.

Clamp Selection Basis (Conditionally Required)

Enter the clamp selection basis code. If you set this option to "Clamp requires clamp-specific service Limits validation" (10) or "Clamp and implied gasket require clamp-specific service limits validation" (15), then the software uses the commodity specific service limits that are define in Piping Commodity Service Limits. Valid codes are listed in the AllCodeLists.xls workbook on the ClampSelectionBasis sheet in the Codelist Number column.

Comments (Optional)

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 clamp that you want to use.

End Preparation (Required)

Type the end preparation code for the mechanical joint. Valid codes are listed in the AllCodeLists.xls workbook on the EndPreparation sheet in the Codelist Number column.

End Standard (Optional)

Type the end standard code for the mechanical joint. Valid codes are listed in the AllCodeLists.xls workbook on the EndStandard sheet in the Codelist Number column.

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.

Nominal Diameter From (Required)

Define the lower bound of the largest nominal piping diameter for which this clamp applies.

Nominal Diameter To (Required)

Define the upper bound of the largest nominal piping diameter for which this clamp applies.

NPD Unit Type (Required)

Specify the units for the Nominal Diameter From and Nominal Diameter To columns. For example, type in for inches or mm for millimeters.

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 (Conditionally Required)

Type the pressure rating code for the mechanical joint. This property defines the envelope of pressure to which the mechanical joint may be subjected. Valid codes are listed in the AllCodeLists.xls workbook on the PressureRating sheet in the Codelist Number column.

Priority (Optional)

Type the priority value that this clamp should have when selecting clamps for a mechanical joint at a piping specification break and the clamp requirements are different between the two piping materials classes. The lower the number, the higher the priority is for the clamp.

Quantity of Alt Reportable Parts (Optional)

Enter the number of alternate reportable piping commodities to be reported per instance of the piping commodity. If you have defined a commodity code in the Alt Reportable Commodity Code column but do not define a value in this column, the software uses a default value of one.

Quantity of Reportable Parts (Optional)

Type the number of objects to be reported per instance of the piping commodity. This value must be an integer.

Reportable Commodity Code (Optional)

Type the commodity code of the piping commodity that you want created with the primary commodity code item. For example, you may want safety covers or housings reported for material control but not represented graphically in the model. You would enter the commodity code of the safety cover here.

Spec Name (Required)

Type the name of the piping material class for which the clamp 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.
