I have the following drained pvc tube pipe. As you can see from the picture below, I want to detach the part that I've circled in green (the upper part).
The pvc part has been glued.
After many readings on the internet, one of the easiest solution would be to use a heat gun/thermal cleaner to unstuck it (like in this video).
Is there a simpler way to unglued the pvc tube without using a heat gun?
Thank you.
You've already accepted, but to properly fix this:
I'll assume it's all polyethylene pipe (typically used for well piping). The fitting also looks like nylon, which in my experience is easy to damage and often leaks. I much prefer PVC (which is typically gray) or brass.
Take everything apart, remove the elbow, and throw it away. Heat the end of the poly pipe with a torch, both around the outside, and a tiny bit on the inside. You want it to be warm, but not melted/squishy/burning. Put on two clamps, then put the fitting in, and then tighten down the clamps (about 1/4" apart, give or take). Repeat with the other end.
If you've never done this, you may want to practice on some scrap pipe first, especially if you don't have a lot of extra to work with. If you do melt the pipe, you need to cut the end back and remove the melted piece.
I see no reason why you should cut threads on a PVC pipe. It seems to me that this would be unnecessarily difficult and would weaken the pipe.
You should, instead, get a slip to thread adapter and glue it onto the pipe to thread it wherever you like. Any big-box hardware store or irrigation department should be able to provide this adapter.
Edit: Here is a link to such an adapter for $1.56at big orange hardware store. :

The glue normally used is a pvc cement and « welds » the joint together.
I would cut that tee out and fit a new one with extensions to meet up with the existing pipes using couplers.
When you get the old part out, try separating a joint - they tend to « tear » the surface.
