Transition Bushings for CPVC IPS to CPVC CTS
« on: Nov 08, 2023, 15:08:10 PM »
We traditionally use two separate services for systems containing both Sch80 Corzan CPVC IPS and CPVC CTS and place a transition bushing manually with attached between them. For example a 3" Corzan main with a 2" Flowguard Gold branch would be 2 separate design lines with a transition bushing between them at the branch connector for the reducing tee.

I have been trying to create a service with both materials in it that will automatically place the transition bushing much like an MIP adapter is placed automatically on both sides of a threaded valve. I have looked at "connectivity" and different connectors and material settings and still cannot get the bushing to populate.

I can however get the Flowguard CPVC to connect directly to the Corzan Sch80. Which is incorrect and forces me to manually place the transition bushing and adjust the branch length into the makeup of the bushing rather than the red tee.

Anything obvious I am missing here? It's driving me crazy.

***UPDATE***

If I manually place a node for the transition bushing at the makeup of the reducing tee branch once populated, it will give me the results I want.

This still requires me to manually place the bushings though rather than them being automatically populated at every location where this transition occurs...

If it fills manually, then the button mapping needs to be modified for this service.  Maybe create a custom code and move it to the top of the list?

Also, if bushing is on a different tab, check the DB setting Takeoff > CAD Settings > Stretch > Restrict to use Items from the same Tab is not checked.

So I thought about this, but it seems like regardless of button mapping it's not recognizing the change in material. So it finds the reducing tee button first and stops there and never makes it to alternate codes.

Somewhere in the database I need to tell it that you can't glue regular CPVC into Sch80 CPVC that has a different O.D.

I have been trying to figure this out for years and nothing I have done has worked.
So I have just told all of our users that they have to manually add the transition bushing or coupling.

It doesn't make much sense because I've gotten more complex stuff to work but this just doesn't seem to want to work.

Yeah, I've had it on the backburner for a few years now too, but it seems more of our jobs are headed this direction when it comes to water distribution so I figured now's the time to figure it out.

Any other system that transitions, it usually happens in the pipe. One end gets grooved and one end gets pressed, or one ends gets threaded and one end gets pressed. Or the fitting that makes the transition has a reduction in size or something else that takes control of how it gets populated.

This specific instance though its the same type of connector and the same "size" on both sides. Makes it very confusing.
