Merge Pipes, Branches and Signal Lines

This procedure is used to merge two main pipes into one main pipe, or two branches into one branch, or to merge a branch into a main pipe, or to merge two signal lines into one signal lines.

The pipes/branches/signal lines to be merged must adjoin each other.

When pipes or branches are merged, the properties of the first pipe/branch selected are adopted as the properties of the merged pipe/branch.

To merge two segments of a single pipe together, refer to Merge Pipe Segments.

For details of the use of this procedure in the context of drawing P&IDs, see Draw Pipes and Connections.

Note: Referenced pipes cannot be merged. An error message will be displayed if this is attempted. Refer to Label by Selection of a Reference Object)

Note: Not applicable to drain pipes.

Procedure

1. Start the procedure by either:

   • selecting the pipe/branch into which the other pipe/branch is to be merged on The Drawing Page, then right-clicking and selecting Pipes>Merge from the shortcut menu (this option is not available for signal lines), or

   • selecting the Merge Branch/Pipe option in the Modify group of the Home tab.

2. If the second method of starting the procedure is selected, the Command prompt will display:

   Pick a pipe group to merge:

   Pick the pipe/branch/signal line into which the other pipe/branch is to be merged.

   If the first method of starting the procedure is selected, a pipe/branch will already have been selected.

3. The Command prompt will display:

   Pick a different pipe group to merge:

   Pick the pipe/branch/signal line that is to be merged into the first pipe/branch selected.

4. The two selected pipe/branch/signal line are then merged. If pipes or branches are merged, the properties of the first pipe/branch selected are adopted as the properties of the merged pipe/branch.
