Label Pipes

The procedure can be used to create and edit labels for pipes (including those drawn as process links). A pipe can have multiple labels. Each segment of a pipe may be labelled, and pipe labels can be placed on either side of reducers and breaks as required. Labels that are associated with a pipe label symbol can be positioned on a pipe, provided the port connections are at the correct location..

Note: Pipes and identified as main, branch or trim pipes when they are inserted. The procedure for labelling all types of pipe is the same.

Associated Project Configuration Options

• To set the last value entered in a Properties dialog field to automatically populate that field that next time that Properties dialog is accessed for an unlabelled item of that item type, use the checkboxes in the Values to Remember from Last Pipe Edit section of the Pipes - Settings Sub-Category of the AVEVA P&ID Project Administration program.

• Inheritance between pipe label and sheet attribute fields is set up using the Pipes - Settings Sub-Category.

• The project may be set to check that pipe labels in all P&IDs in the project are unique using the Label Validation across P&IDs section of the Pipes - Settings Sub-Category.

• If required, the cascading to branches of changes to properties of the main pipe can be disabled for specified properties using facilities in the Cascade Settings section of the Pipes - Settings Sub-Category.

• The maximum and default process link sizes are selected from the Maximum Allowable Size for Process Links and Default Size for Process Links lists on the Pipes - Settings Sub-Category.

• The format of pipe labels, for example, the components of the labels and the order in which they are placed, are defined in the Pipe Label Format section of the Pipes - Labels Sub-Category.

• The format in which pipe labels are displayed on a drawing, which may differ from the actual format, is defined in the Display Label Format section of the Pipes - Labels Sub-Category.

• The display format of source and destination labels where the source/destination is a different pipe may be different from the normal display format. If required, this facility is switched on an defined in the Source and Destination Formats section of the Pipes – Labels Sub-Category.

• The delimiter is specified in the Delimiter field.

• Whether or not display labels for pipes are to be validated against a regular expression is controlled by the Apply Regular Expression for Label checkbox. The expression is entered in a dialog accessed by pressing the button next to the Regular Expression for Label field.

• The project may be set to require that a selected field or a combination of fields in instrument labels be unique (in addition to the entire label being unique). The fields that are checked for uniqueness are selected in the Unique Validation field of the Instruments - Labels Sub-Category.

• Use the Trim Label Prefix field to specify the text prefix to the trim identifier in a trim label.

• The names of the ten project defined fields that may be part of pipe labels are established in the Project Definable Fields section.

• If split labelling is required, use the Split After Field field in the Split Format section to indicate which field in the pipe format to split on. The 'Y' Offset Above Line and 'Y' Offset Below Line fields are used to specify the distance that the 2 parts of label are placed above and below the line.

• The colours, heights, styles, and other formatting attributes of the parts of a split pipe label are defined by setting the properties of the XPO (first part), XPB (second part), XBO (third part), and XBT (fourth part) label types in the Label Types Configuration Category.

• Whether or not instrument valves can appear as the source and destination of pipes, and the list of instrument valves types that are to behave in this manner, is set using the Pipe Instrument Labelling checkbox and the Instruments Allowing Labelling fields in the Display Instrument Labels at Pipe Destination section.

• Pipe labels in fixed label format may automatically have a symbol placed with them when they are inserted. For example, they may be placed in a flag symbol or box. This functionality is switched on and off, the required symbol selected, and the offset from the label specified using the Pipe Label Symbol section.

• If split label formatting is to be used and a pipe label symbol is to be used, up to four label fields may be positioned before the split in the selected label symbol, as defined in the Define Split labels and offset for symbol section.

• The distance of single pipe labels from pipe segments may optionally be specified in the Fix Single Pipe Label from owner segment section.

• If a user may specify which of a pipe's labels is the default label, which will be used to identify it in the database, this facility is switched on in the Default Reporting Label Format section. The colour used to highlight such labels on drawings is also set in this section.

• Whether pipe labels are to be automatically placed in the middle of pipe segments, and rotated parallel to them is controlled by the Automatic Pipe Label Placement checkbox. The Offset Distance field is used to specify the distance that pipe labels will be offset from pipes in this field.

• Automatic tagging of pipe number fields, refer to Automatic Tags, is switched on and formatted in the Equipment - Automatic Tag Format Sub-Category.

• Nozzle sizes may automatically be cascaded onto connected pipes, depending on the setting of the Cascade Nozzle to Pipe checkbox in the Nozzles - Settings Sub-Category.

• User-defined lists of values for all pipe properties can be set up and associated with a selected pipe specification using the List of Values Configuration Category. If that spec is selected for a pipe, only those lists of values are available when specifying the pipe properties in question.

• Whether or not auto-labelling is on by default is set in the Miscellaneous - Labels Sub-Category pane.

• The pipe styles that pipes can be set to can be restricted based on their specification. Pipe styles are associated with specification using the Spec Driven - Pipe Styles Sub-Category.

• Lists of values for pipe properties (Spec, Size, Fluid and Area) may be created that are only available for specific drawings, and which must be used when specifying pipe properties for those drawings. Refer to Create Pipe Property, Symbol and DataSet Filters based on Drawing Attributes.

Procedure

Label an Unlabelled Pipe

1. Use this procedure when labelling a pipe for the first time, or when editing the properties of a pipe. For new pipes, The procedure may operate automatically if auto-labelling for pipes is on. If this is the case, pipes nodes are placed and the AVEVA P&ID Pipeline Properties dialog displays automatically when the pipe is drawn.

   If auto-labelling is not on start the procedure by either:

   • selecting the pipe to be labelled on The Drawing Page, then selecting Properties from the shortcut menu, or

   • selecting the pipe to be labelled in the Engineering Explorer, then selecting Properties from the shortcut menu, or

   • selecting the Properties option in the Properties group of the Home tab.

     Note: Labels can also be viewed using the Non-Modal Properties Dialog, but tags cannot be directly entered into this dialog. Other details can be entered or changed however, and the drawing labelled with them.

2. If either for the first two methods is followed, the pipe is already selected.

   If the other method is followed, the Command prompt will display:

   Select Item to Label, or Label to Modify:

   Pick the pipe.

3. The AVEVA P&ID Pipe Properties dialog is then displayed:

   

4. The properties of the pipe can be completed by selecting another pipe. Select Yes from the Reference field then select the referenced or "parent" pipe from the Reference Pipe field.

   The current item is then labelled with all the pipe head properties of the referenced pipe, including the tag properties, UDAs and DataSet values. Any properties already entered for the child object, including inherited properties, are replaced.

   Changing the properties of the "parent" item will automatically change the properties of the "child" item, and vice versa. The following message will be displayed to alert the user of this:

   

   Note: When an item is first populated by referencing another item, its properties cannot be edited. The item must be first be saved and the Properties dialog reopened.

   Note: Referenced pipes cannot be split, merged, or have a different segment set as the main pipe segment.

5. If the pipe is not to take its properties from a referenced item, complete the entry fields with the required pipe label data:

   • Select YES in the Inheritance field if the pipe is to subject to attribute inheritance from the sheet.

   • Select YES in the Bi-Directional Flow field if the pipe is to be dual flow.

   • If the pipe is not dual flow, the flow direction can be reversed by selecting YES in the Reverse Flow field. Refer to Reverse Pipe and Signal Line Flows.

   • Complete the Pipe Segment Properties fields.

     Note: The number field may be completed automatically. See Automatic Tagging. Automatically entered number fields may be manually overwritten if required.

     Note: If the pipe is a Process Link (functionally a Process Link, not just drawn in the process link style), then the Size field may be restricted to a maximum value, depending on whether such a maximum has been set (see Associated Project Configuration Options above).

   • Select the style of pipe, for example, its appearance, in the Pipe Style field, or leave it set to the default style. The default pipe style is set using facilities in the Pipeline Group of the Home Tab.

     Note: The pipe styles that pipes can be set to can be restricted based on their specification. Pipe styles are associated with specifications using the Spec Driven - Pipe Styles Sub-Category.

     Note: A Process Link pipe style is available. Pipes drawn using this method will look like Process Links but will functionally be Pipes.

     

     Note: Valve and reducer symbols may be restricted so that they can only be inserted into pipes with specific spec codes and sizes. This is setup using the Spec Driven Configuration Category of the AVEVA P&ID Project Administration program. When the spec or size of a pipe is changed, the system checks whether or not the symbols inserted into the pipe would still be valid for the new spec code or size of the pipe. If any would not be valid, the change may be prevented, or a warning displayed, depending on the project setup.

     Note: Pipes may be added to a pipe group, created for reporting purposes. If a pipe has been added to a group, details of the group are also displayed in the dialog. They may not be edited. Refer to Create Pipe Groups.

     Note: Lists of values for pipe properties may be set up using the List of Values Configuration Category of the AVEVA P&ID Project Administration program which are associated with a pipe specification. If that spec is selected for a pipe, only those lists of values are available when specifying the pipe properties in question.

6. If the pipe label is to be displayed on the drawing, select Yes in the Add Label field (this is the default setting). If the label is not to be displayed select No. This field is not displayed when editing a pipe that already has a label displayed

7. The Command prompt will then display:

   Position pipe label:

   Pick a point for the pipe label. If a symbol, such as a box, is set to be placed with the label, it is inserted automatically at the same time as the label.

   If the split pipe labelling is being used, splitting of the label occurs when the label is placed on top of the pipe.

   If the Fix pipe label position for single labels setting is in used, the pipe labels will automatically be placed the specified distance from the owning segment, on the side of the segment that the user clicks on.

Position Pipe Label Symbol on a Pipe

8. Use this procedure to position a BPI or LIG pipe label symbol type on a pipe.

   Select a pipe label symbol by using the Symbol Explorer.

   After the symbol has been selected a 'ghosted' image of the pipe label symbol will appear on the cross hairs. The Command prompt will display:

   Insertion point:

   Pick the desired position on the pipe. The pipe label symbol is then placed.

   Place another item, or select Cancel from The Drawing Page menu or press Ctrl-C to end the command.

Add Extra Labels to a Labelled Pipe

9. Use this procedure to add labels to a pipe that has already been labelled, e.g. to unlabelled segments of such a pipe.

   Start the procedure by either:

   • right-clicking on the label of the pipe and selecting the Add Label option from the shortcut menu, or

   • selecting the pipe to add a label to and selecting the Add Label option in the Properties group of the Home tab.

10. If the first method of starting the procedure is followed, the following menu is then displayed:

    

    If the segment is to be labelled with the entire label of the pipe, select the Full option. Continue at step 4.

    If the segment is to be labelled with only a single property of the pipe or a custom label, select Customize from the menu. The Add Label dialog (see next step) is then displayed.

11. If the second method is selected, the Add Label dialog is displayed:

    

    If the segment is to be labelled with a full pipe label, in the default Display Label Format specified in the project configuration, select the Full Label option from the top list.

    If the segment is to be labelled with only a single property of the pipe, select the Single Label option from the top list, and the property, e.g. Size, from the list below it.

    If the segment is to be labelled with a different Display Label Format from the default, select Custom Label from the top list, then select the required format from table beneath the lists.

    Click Add Label & Close to add the label and finish the procedure. Click Add Label if further labels are to be added to the pipe using the dialog.

12. The Command prompt will then display:

    Position pipe label:

    Pick a point for the pipe label. The label is then placed.

    If the Add Label & Close button was selected, the command then ends. If the Add Label button was selected, the above dialog is displayed again. Add further labels as described above.

Set a Pipe Label as the Default Pipe Label

A pipe may be labelled with labels in various formats. Depending on the project configuration, one of these labels may be set as the default label, for example, the label that will be used to identify the pipe in the database.

To set a pipe label to be the default pipe label, right-click on the pipe label on the drawing page, then select Set as Default Label from the shortcut menu.

Depending on the project configuration, the selected label may then be displayed in a different colour.
