I don't think that anyone here would argue if we use a small piece of pipe to protect a piece of RX. However the big question is, When is the pipe too long? A 4' piece is OK? Then how about a 10' lentgh? Maybe 20 or 30 feet? When do we stop. I saw a job where someone ran 60-90 feet of PVC with a 12-3 RX inside of the pipe. Is that too much? What is the code section? Now if it goes underground, you can argue the RX in a wet location like ElectricAl stated. However how much pipe is too much? Maybe you could ask the AHJ?

I agree Russ. How can moisture get to it if you use compression fitting.

Good point Harold, I just can't see where the problem is with running NM in pipe if it is weatherproof.

I'm with you Attic Rat on this, as I can not even get THWN,it is not even stocked at our several supply houses! I use THHN in conduit outside all the time! (Listed for damp location.) Maybe something unenforced here? Not that I'm looking for it to be, I like stocking one type of wire.

Wait, I just checked, its all dual rated............. THHN/THWN/MTW, just says THHN in larger lettering. Duh.... Just when you thought you could break some rules.

Oh, most RT fitting only become RT as they cross into Canada. There is something I get away with!
