Another part of the stored model is pipe sets, a pipe set is a collection PIPES in the context of AVEVA Process Simulation. A Pipe in this window is a pair of connected nodes linked by a connector which is represented by the pipe symbol in the APS model. A base pipe set is created at the same time as the nodes are generated and it represents the fluid flow between linked nodes.
The base pipe set can be viewed by selecting View Base Pipes from the Process Simulation Interface window.
Note:
Selecting individual rows in the base pipe list automatically highlights the connected
elements in the 3D model. This enables the visualization of the connected model flow
and highlight potential problems.
The base pipe set includes all the node pairs in the model, including pipes connecting ignored nodes. It is possible to export the base pipe set to AVEVA Process Simulation, but the resulting model would contain disconnected ends due to vents, drains or inline branch breaks.
Observe pipe links node 5 the tail of the branch at node FP1/B1-1 If this is exported to APS the result would be an unconnected end and the following pipe would have an unconnected start. Both would need to be connected manually in APS. To avoid this sort of problem, there is a further process required, to generate the pipe set to be exported to APS. This is known as the Merged Pipe Set, which is a pipe set with ignored nodes removed and what should be a continuous model for output to APSI. The merged pipe set can be built using the right click menu in the group list box.
Building the merged pipe set activates View Merged Pipes button which allows the final model to be exported to file.
Like the Base Pipe List, stepping through the rows shows the sequence of pipes within the model. Below it can be observed that pipes 5 and 6 from the base pipe set have been merged to form a new pipe 5 which runs from node 5 to node 7 ignoring the branch break.
The new pipe 6 now runs from node 7 to node 8.
The new pipe 7 runs from node 9 to node 12, replacing pipes 8,9 and 10.
