Drawing Pipes and Connections

Pipes are drawn in the current style and with the current tracing and end styles. These are set in the Pipeline group of the Home tab. Pipe styles are created and amended by selecting the Pipe Styles option in the List of Values Configuration Category of the AVEVA P&ID Project Administration program.

Note: The flow direction of a pipe defaults to the direction it was drawn in. Pipe flows can be reversed or set to dual flow if required. Refer to Reverse Pipe and Signal Line Flows and Label Pipes.

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

Note: For further guidance on creating piping networks, refer to Piping Network Creation Options for Drafting Designers.

A pipe can be drawn directly from a selected nozzle.

Associated Project Configuration Options

• If pipes are to be broken automatically when crossed, the Automatic Breaks ON checkbox, in the Pipes - Settings Sub-Category of the AVEVA P&ID Project Administration program must be checked.

• The break priority, for example, whether the horizontal or vertical pipe is broken where a break occurs, is set using the Break Pipe Direction buttons.

• The width of the gap in a broken pipe is set in the Break Distance field.

• The symbol chosen to represent the break is selected in the Symbol Name field.

• The layer into which break symbols are placed is specified in the Symbol Layer field.

• Layers are configured using the Drawing - Layers Sub-Category.

• The colour of the break symbol is set in the Symbol Colour field.

• If flow arrows are to be automatically placed at direction change mid points of pipes, make sure that the Insert Arrows at pipe segment mid point and Automatic Arrows checkboxes are checked in the Flow Arrows section..

• Specify the symbol to be used to indicate flow direction in the Symbol Name field (below the Insert Arrows at pipe segment mid point checkbox) of the Flow Arrows section.

• If flow arrows are to be automatically placed at direction change end points of pipes, make sure that the Automatic Arrows checkbox is checked.

• Specify the symbol to be used to indicate flow direction in the Symbol Name field (below the Automatic Arrows checkbox) of the Flow Arrows section.

• Specify the symbol to be used to indicate dual flow in the Symbol Name field of the Dual Flow Arrows section. Enter the distance between flow indicator symbols in the Offset Distance field.

• If the USER_STOPUPDATEANNOTCOLOUR user-defined directive in the Miscellaneous – Settings Sub-Category is set to Yes, intelligent entities, including pipes, will not have their colours changed to match changes to project settings in the Administrator.

Procedure

1. Start the procedure by selecting the Draw Pipeline option in the Pipeline group of the Home tab.

2. The Command prompt will then display:

   Indicate point for Main pipe:

   Place one end of the pipe.

3. The Command prompt will then display:

   Indicate point for Main pipe:

   Place other the end of the pipe or the first turning point. The length of pipe then appears on the drawing.

   If an offsheet connector was selected as the pipe end style for the beginning of the pipe, it will be inserted and orientated automatically.

   AVEVA P&ID will continue to prompt for end or turning points. Continue placing these until the pipe is finished.

4. The Command prompt will then display:

   Indicate point for Main pipe:

5. Press or select Enter to end the command.

   If an offsheet connector was selected as the pipe end style for the end of the pipe, it will be inserted and orientated automatically.

If auto-labelling for pipes is on, the Label Pipes procedure will then start automatically.

If both auto-labelling and auto-validation are on, the Labelling Pipes procedure will then start automatically.

Pipe end styles are selected, and auto-labelling and auto-validation are switched on and off using facilities in the Pipeline group of the Home tab.
