How to loosen nipple from sink to main drain

trying to remove old nipple from sink drain into drain line. Both are cast iron and very old. Nipple willnot budge, is there any tip for getting it loose?

Maxjakes, Welcome to the DIY Forums.
The nipple SHOULD be galvanized pipe and threaded into the cast iron fitting in the wall. It is, no doubt, corroded. Try tapping lightly on the pipe with a hammer as you put pressure on the nipple with a pipe wrench. Vibration works great for loosening corrosion. Good luck.
