Piping
Model Pipe
Before modelling a pipe, the correct database elements should already be present in the Model Explorer, for example, a World, Site and Zone should exist. If this is not the case, refer to Database Hierarchy for more information.
|
•
|
|
•
|
|
•
|
Below the zone level in the PIPING discipline, the specific elements are:
Piping elements cannot be created or modified, if the correct database hierarchy has not been configured beforehand or if the correct current element has not been selected in the Model Explorer. For example certain piping elements must reside below other elements in the database hierarchy (an overview of the database hierarchy is described in Database Hierarchy).
By default the Primary System is No System, to change the type of primary system select a system from the Primary System drop-down list.
The Bore specifies the nominal bore and does not affect the pipe route (the default is unset).
Select an Insulation specification, if no insulation is required (the default is None), select None.
|
Note:
|
In Temperature, enter the temperature to which the pipe can reach (the default is ‑10000degC, this means that the temperature is ignored).
In Pressure, enter the pressure to which the pipe must withstand (the default is 0pascal).
The Slope Ref specifies the slope reference attribute, which is governed by the catalogue (the default is none). To change the slope reference attribute, select a slope reference from the Slope Ref: drop-down list.
Click Apply, to create a new pipe and branch element in the Design database and display the Pipe Editor: Modify Pipe window, to define the branch, refer to Branch Element for further information.
The Pipe Editor: Modify Pipe window displays by default when a new pipe element is created. It is a dual purpose window which allows the definition of branch attributes and/or connect the branch head and branch tail or modify an existing branch.
By default, the Pipe Editor: Modify Pipe window is populated with the attributes of the CE, if required, select another pipe as the CE.
 |
Use the Pipe Editor: Pipe window to select an alternative Pipe Specification by clicking Modify Pipe Attributes to display the Pipe Editor: Modify Pipe specification window.
The Pipe Editor: Modify Pipe specification window has the same functionality as the Pipe Editor: Create Pipe window, refer to New Pipe Element for further information.

The Branch Head and Branch Tail tabs on the Pipe Editor: Modify Pipe window, are used to define the connection and position of the branch head or branch tail. As the functionality for the definition of the branch head or branch tail is identical, for the purposes of this user guide, only the branch head definition is described. By default the branch head tab is selected when the Pipe Editor: Modify Pipe window displays.
For example, to define the head of the branch, make sure the correct branch is highlighted in the design database and the correct branch name displays in the Connectivity part of the of the Pipe Editor: Modify Pipe window.
The Branch head tab of the Pipe Editor: Modify Pipe window is used to connect the branch head and define basic branch head details, the connection status of the selected branch displays by default:

The Insert Depth value varies according to the Branch Type selected and is calculated using a set of standard calculations for branches on centreline. In some cases the calculation may need to be adjusted by eye to provide a more accurate material length. To do this enter a value into the Insert Depth field. The value shown in this field can be one of three types:
|
the current value entered but not yet fixed by clicking Apply. The button to the right of the insert depth will swap the insert values between actual and default.
For example if the default is 4.75mm and the actual is 14.57mm clicking Default will change the insert depth to 4.75 and the button will have a display of Actual. Clicking it again will return the insert depth value to 14.57.
