Big hammers usually help. Get a good deadblow hammer or a block of wood and a small sledge should knock things loose. If that doesn't work, get a good penetrating oil like PB Blaster, and I saw another one by CRC that is supposed to use some kind of freezing action to break the rust, but heat the pipes with a torch and then spray the penetrating oil at the joint. Repeat a few times and let sit. Then have at it with the hammer.
