Removing End Of Broken Pipe From Pot Manifold

[Pollys13]

After receiving advice on the forum, thanks I bought a set of nipple extractors. Using a butane torch to free up the Loctite stuff. I'm wondering how the paint might react with the heat? If powder coated I have a feeling, it will pretty much stay put. If another finish might flake and bits fall into the 120 grit, which I think should be avoided if poss.
So should I fit the nipple extractor into the end of pipe, then heat up, would perhaps expand the extractor making a tighter fit but could also expand the end of the pipe making harder to get out? I'm thinking of a 10 second burst with the torch, which I've used to get other fittings off, is 10 seconds too long?
Please advise.
Cheers.

More heat the better sometimes! When loosening off track rod ends, They don't start moving until they're cherry hot

Um, too much heat can't do any harm, unless something delicate close by, more heat than less is best then. Do the various types of threadlock, sealents, do they reset after they cool down?

@Pollys13 just got to be sensible about it.

I would just use clean up & use new sealant/threadlock

I've quickly Googled but couldn't find anything, is clean up a product?

No, Wire brush

No, Wire brush

OK thanks.

After wire brushing, a squirt of break cleaner, on the thread, and in the hole, blown out with a air gun, then your thread lock.

That's what I've been taught.

Almost as important as the heat is to make sure the rest of the part is held or positioned so you can get plenty of pushing force on the extractor as you turn, remembering that cast Chinese stuff is like crumbly cheese.
You might have to slit the broken part with a hacksaw blade in a few places then get it out with a pick tool and a small chisel.

OK thanks for the input people.
