Managing pipelines

In CADMATIC P&ID and Plant Modeller, you can manage pipelines by selecting File > Environment > Systems and Lines.

Tip: You can also manage pipelines via File > Environment > All Library and Project > [project] > Pipelines. New pipelines can be created via the Model Tree pane, as described in Managing tree items.

Creating a new pipeline

Do the following:

1. Select File > Environment > Systems and Lines. The Systems & Lines object browser opens.

2. Right-click the System where you want the new pipeline to be created, and select Add Pipelines.

   

3. Specify the pipeline details:

   1. Enter a name for the pipeline. The maximum length is 100 characters.

      Note: If the pipeline is to be used in the P&ID application, the name cannot be the same as the name of its System.

   2. Select one or more piping specifications for the pipeline, as appropriate. The maximum is five different piping specifications.

   3. Select the option Allow Out of Spec Parts if also piping parts that are not included in the specifications can be used.

   4. Select the option Insulation Required if having insulation is mandatory in this pipeline.

   5. Select one or more insulation specifications for the pipeline, as appropriate.

   6. Select the option Use in Plant Modeller to make the pipeline visible in the Plant Modeller application.

   7. Select the option Use in Piping Isometrics to make the pipeline visible in the Piping Isometrics & Spools application.

   8. Select the option Use in Diagram to make the pipeline visible in the P&ID application.

4. If you want to add object attributes to the pipeline, click Attributes.

5. Click Add to create the pipeline.

6. When you have added all the required pipelines, click Close.

We recommend to define and design pipelines as follows:

• Pipeline has only one piping specification and insulation specification.
• Pipeline has one clear starting point and one end point.
• Pipeline is continuous and the design properties are the same throughout the pipeline.
• The mass flow of flow media is constant throughout the pipeline.
• There are only branches without remarkable continuous mass flow like sample takings, air removals, flushing, drain.

Editing diagram attributes

When you open the Systems & Lines dialog using either CADMATIC P&ID or Plant Modeller that is using P&ID integration, you can edit the values of pipeline attributes that are stored in the SQL database.

Prerequisites

• Optionally, add the columns of the attributes you intend to edit to the Systems & Lines dialog, so that you can easily see the attribute values before and after the change. See Object browser columns.

Do the following:

1. In the Systems & Lines dialog, select the pipeline or pipelines whose P&ID attribute values you want to edit.

2. Right-click the selection and select Edit Diagram Attributes.

   

3. If you are editing a single pipeline, the Select Attributes to Edit dialog opens. Select which attributes you want to edit, and click OK.

   

4. The Edit Diagram Attributes dialog opens, and its content depends on whether you are editing a single pipeline or multiple pipelines.

   • If editing a single pipeline, the dialog lists only those attributes that you selected in the previous step.

     Click Select Attributes if you want to add more attributes to the list.

     

   • If editing multiple pipelines, the dialog lists all those attributes that have exactly the same value in the selected pipelines.

     Click Select Attributes if you also want to set a single value to an attribute that currently has several different values in the selected pipelines.

     

     Note: An attribute whose value is not the same in all the selected pipelines displays an empty value field until you enter a value in it.

5. Enter the new values, and click OK.

   The modified values are stored in the SQL database and displayed in the object browser if the related columns are visible.
