Reply to comment by D-Honey in What is the next step for replacing broken pipe under kitchen sink? by protolalia

Do you have any advice about how to dislodge the pipe? I sprayed the connection with WD40, and I'm grabbing the pipe with a plumbers wrench near the connection. I can't get it to budge or twist even a little.

You could try a propane torch Heat the pipe to expand it

You should get some penetrating oil. PB B'laster is one, Kroil is another brand. Spray that on the threads and leave it for an hour or so. They will work their way into the threads by capillary attraction and lubricate the stuck parts.
