1               General Information

Using the piping design, you can easily create and edit pipelines and networks. The assistant can only be used for sheets of the smart diagram type P&I Diagram.

A pipeline network can be composed of the following objects:

·            Beginning and end of the pipeline: The beginning or the end of a pipeline network is either defined by pipeline breaker shapes or by process / fluid devices with the Boolean attribute Pipe Destination set.

·            Pipelines: Pipelines may be subdivided into segments by means of pipeline segment breaker shapes if the segments are to be designed differently (e.g. Cross section, material, …).

·            Devices that are built into the pipeline.

The flow direction of a pipeline network is defined by the connected pins. In the Flow Direction attribute of a pin, you can define the values In, Out and Unspecified. The flow direction of a pipeline is indicated in the graphics by an arrow. Within a pipeline network, the values of the Flow Direction attribute are checked at the connected pins.

If all pins either contain the value In or Out, an error is shown at all connected pins.

In the piping design, the specifications of the Rule Based Design are also taken into account. The network is checked to see whether the specifications made are met. If this is not the case, these errors are marked in the graphics and an entry is created in the conflict list.

In the piping design, editing the graphics takes precedence. Manual entries in the pipeline attributes may be overwritten.

If a pipeline is created on a connection to which a flow stream or a potential/substance is allocated, the connected pins of the type Process/Fluid are associated with the flow stream or the potential/substance. If a conflict is identified, an entry is created in the conflict list.
