I have a 2" galvanized drain pipe that was so corroded that it literally fell out under its own weight. The pipe threads are corroded/fused into the 45 fitting, and I can't get them out of the fitting (tried wire brush, hack saw, etc. The galvanized pipe was touching a copper pipe, and I suspect it might be the cause of this level of corrosion right at the fitting.)
I need to connect to this drain, and I'm looking for ideas how to connect. Normally, I would just cut the fitting out and use a Furnco to connect PVC, but this fitting is jammed against a joist (and subfloor), and I'm not sure there is enough room for a 3.5" long Furnco then a PVC 45. On the other side of this fitting is a short nipple and then a CI toilet flange with this 2" inlet. There is no room to unscrew the nipple- I'm pretty sure the nipple and 45 were attached to the toilet flange before it was installed because there is no room to turn it.
This drain serves just a hand sink (lav) in a rarely used third floor bath.

time for a pro
1. try notching and slicing the broken off threads then chasing with a pipe tap
2. try 'busting out' the Cast Iron fitting using TWO hammers - one 'static' behind and touching tp absorb the blows
3. THEN you can use a 'fernco type' coupling, shielded and banded preferred of course

Soak in Kroil overnight and remove the 45 degree fitting.
Alternatively slowly chip away residue male pipe, wire brush/pick and rethread the female threads.
