That may work, and I am not super experienced with copper... but generally to get a useful anneal you have to hold at temperature for around 30-60 minutes and cool slowly to avoid forming hardened compounds. I could be wrong though.

I've done it with copper head gaskets before, just used a propane torch, I've not done it with copper pipe though. It works the opposite of steel.

I think this demonstrates pretty well the annealing of copper.


I've found that you don't have to quench the copper, you can just let it cool slowly or quench it, either works.

overall... I'd buy tubing instead of rigid copper, but this might be useful for a dip tube.
