Create Pipeline (PE)

Use this function to specify a name for the pipeline. The name suggested by HiCAD is PIPELINE_, followed by the lowest possible number which has not yet been assigned in the current drawing.

If you select another number, the system will check whether this number has already been assigned. If this is the case, an appropriate message will be issued. Instead of the name suggested by HiCAD you may also select an arbitrary name.

When you create a pipeline, HiCAD automatically create two parts in the active drawing: a main part PIPELINE_nnnn and a sub-part ~Parts.

New pipelines can be directly created as sub-parts to the active part. For example, if you want the new pipeline to belong to an assembly, call the Create pipeline function and activate the as sub-part checkbox.

You can assign a Pipe class and a Nominal diameter to the pipeline. This specification ensures that you can only insert parts fulfilling the criteria determined by the pipe class and nominal diameter in the pipeline. If you want to assign a pipe class, activate the Assign pipe class checkbox. You can now choose between three options:

Pipe class from P+ID
This setting is only possible if:

• you are currently working with layout plan that is linked to a P+ID, and
• the P+ID project is loaded.

or

• if the current drawing contains referenced 3-D assemblies that are linked to one or several P+IDs, and
• one referenced assembly is active, and
• one of the P+IDs loaded together with this assembly is active.

If you click the Select P+ID symbol, HiCAD automatically switches to the appropriate P+ID. You can now use the cursor to select the pipeline symbol (represented by the graphic text of its alias). You can display the appropriate data mask and the data of the assigned pipe class. When you select the symbol you are automatically returned to the layout plan and the dialogue box described herein. If you have assigned a nominal diameter to the P+ID symbol, it will be displayed as well and applied to the pipeline to be created. If no nominal diameter has been assigned to the P+ID symbol, this will also apply to the pipeline to be created. If no pipe class, but only a nominal diameter has been assigned to the P+ID symbol, the checkbox is switched automatically and the nominal diameter will be displayed under Assign nominal diameter.

The name of the pipeline will also be adapted from the P+ID.

Pipe class from database
When you click the Select pipe class button, the HELiOS displays the Find pipe class mask enabling you to start a search. When you select a pipe class, HiCAD returns you to the dialogue box that now displays the required pipe class. If you previously selected or now select the nominal diameter checkbox in the lower part of the dialogue box, you can select a nominal diameter valid for the selected pipe class.

Pipe class from file list
Click Select pipe class. HiCAD shows a list of all pipe class files (XML) available in the sub-folder \PLANTPARTS\PIPECLASSES. This option is only available if you have selected the HiCAD Catalogue as part data source (see Plant Engineering Settings, Part selection).

Pipe class from reference part
This option enables you to apply the pipe class and nominal diameter from a reference part belonging to a part in an existing pipeline. First, click the Select part button. Next, use the cursor (or press the right mouse button to call the Part selection menu) to select a suitable part. HiCAD returns you to the dialogue box that now displays the required pipe class.

If you want to assign a nominal diameter, please note the following:

• If one of the options Pipe class from database or Pipe class from file list is active, the nominal diameter of the pipe is determined by the pipe class.
• In other cases you have the option to:
• take over the nominal diameter from the same part, or
• select the nominal diameter from the nominal diameters available in the pipe class.

If you do not want to assign a pipe class, but a nominal diameter, deactivate the Assign pipe class checkbox and activate the Assign nominal diameter checkbox .

You have now the following options to specify the nominal diameter to be assigned:

Nominal diameter from reference part
First, click the Select part button. Next, use the cursor (or press the right mouse button to call the Part selection menu) to select a suitable part. HiCAD returns you to the dialogue box that now displays the required nominal diameter.

Nominal diameter via direct specification
Enter a value for the nominal diameter you want to assign to the pipeline in the input field.

Use this function to assign specifications concerning the placing of parts on branching points. This takes place via the name of the file containing the corresponding definitions. Click the symbol to edit the definitions for the file.

If a file has been assigned, the definitions in this file, and not those ones belonging to the file that is set as the global presetting in the Plant Engineering Settings. But the definitions in the assigned file, too, will only be used if the Use presettings for placing of parts on branching points checkbox has been activated.

The name of this assigned file will be saved, together with the other properties of the pipeline, when saving a configuration. If a pipe class has been assigned to the pipeline as well, the standard designations that may have been specified in the definitions will be ignored.
