Use the Non-standard Branch Connections window to connect existing branches.

From the Main Branch pane, click Select, the prompt Identify Main Branch is displayed. Once the selection has been made, the selected branch name, bore and wall thickness are displayed in the Non-standard Branch Connections window and the Connect Existing Branch check box is automatically selected.
From the Select Branch pane, click Select, the prompt Identify Stub in Branch is displayed. Once the selection has been made, the branch connects to a cartesian point (PIPCA) owned by the component. The selected branch name and bore are displayed in the Non-standard Branch Connections window. As the branch is not yet connected the Current connection details part of the Non-standard Branch Connections window head and tail are not connected.
Use the Connection Details part of the Non-standard Connections window, to set the connection and tapping type, bore size and insert depth.
The actual connection can be edited by changing its type, or adding a connection component such as a half coupling.
The Branch Type can be selected from the drop-down list:
|
Insert Connection |
The branch tube is inserted into the main branch and welded. |
|
Surface Connection |
The branch tube is placed on the main branch and welded. |
|
Saddle Connection |
The branch tube is shaped to fit on the main branch and welded. |
|
Extruded Connection |
The main branch tube is shaped by machine to form a tube to tube connection. |
|
Boss Connection |
a fitting is selected from the spec and it is welded to form the branch connection. |
Note:
Boss type elements must be in the branch specification, have a gtype of COUP and COMPTYPE
eq 'PTAP' to be recognized by this application.
In the Note field, add a fabrication note which will appear on the piping isometrics
The Insert Depth value varies according to the Branch Type selected and is calculated using a set of standard calculations for branches on centerline. 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:
|
Insert Depth (Default) |
the standard calculation for this type of branch. |
|
Insert Depth (Actual) |
the actual insert depth on the current connection. |
|
Insert Depth (User) |
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. |
Click Apply to create the connection or click Dismiss to discard any inputs and close the Non-standard Connections window.
