Deleting PRV

Is there any way I can remove PRV without deleting or changing the length and orientation of pipes attached. I don't want to change the pipe length, it is happening when am duplicating it to remove PRV.

  • One method is to convert it to a Junction.

    If you only have a couple of PRVs to convert, this is easy to do by clicking the Junction button and placing one directly on top of the PRV, and it will ask if you want to morph the PRV to a Junction.

    If you have a large number to convert, select all the PRVs you want to change and go to Tools --> Batch Morph, choose Selection, and New Node Type Junction.

    Both of these methods will preserve the Elevation, Zone, GIS-IDs, and Notes of the PRV.

  • Thanks for your reply. But there will be an extra junction if I morph. I tried to merge with adjacent node, but the bend in the pipe is getting straight. So what should I do to get rid of the new junction.
  • If you want to merge the two pipes into a single pipe but keep the bend and the appropriate lengths, and you don't want to redraw the pipe manually, you can accomplish this using Skelebrator.

    Here's a workflow you can use to get Skelebrator to only modify these particular pipes (and not change anything else in the model):

    0) Save the model and make a backup copy before trying this, in case something goes wrong.
    1) Morph the PRV to a Junction as described above.
    2) Select the Junction and the pipes on either side.
    3) Edit --> Invert Selection (This will select everything *except* those pipes and junctions).
    4) Under Selection Sets, choose the dropdown for Create From Selection. Note the name of this selection set (it will be something like 'Selection Set - 1').
    5) Open Skelebrator.
    6) With 'Default Skelebrator Group' selected, go to the Protected Elements tab. There is a blue arrow to the right labeled 'Select From Drawing'. Click this.
    7) This brings up the Select toolbar. Find the dropdown arrow and click the Selection Set that you created, then click the green check mark to confirm. This tells Skelebrator that you don't want it to change any of those elements.
    8) Right click Series Pipe Merging and click Add Series Pipe Merging. The default options will probably be fine, but if you can adjust them if needed.
    9) With the Series Pipe Merging item selected, Click the green 'Automatic' run button. This should merge just the selected pipes, keeping the bend in place, and not impact anything else in the model.

    Here is another approach. This may not be a good option if the pipes have a lot of bends or if this needs to be done in several places in your model.
    1. Note the pipe lengths.
    2. Right-click on pipe you want to keep (near the junction you want removed) and select Reconnect.
    3. Select the node you want that pipe to connect to.
    4. Add bends were you want them. To do this, right-click on the pipe, select Bend, then Add Bend.
    5. Set the pipe's "Has User Defined Length?" to True and enter the summed length of the original pipes.
    6. Delete the replaced pipe and the PRV.
