The only time I worked with two inch pipe, it took some monster big
wrenches. And a fireman who lifted weights. I can easily imagine the appeal
of an epoxy patch. One time, myself and my boss both wrenched on one
fitting, and the two of us working together didn't have enough power to
loosen the thread. The job boss, a fireman, did what us two cripples could
not.

One trick I've heard, but not tried. Heat the fitting with a torch. As the
fitting is cooling, use a wax candle to drip paraffin on the threads. The
fitting cools, and sucks in the paraffin, which lubricates the threads.
Please let us know if this does any good.

Usually I just cut the pipe with a sawzall, leaving the stub of pipe
sticking out of the fitting. Then I cut 2 small notches inside the
stub, cutting it in 2, and it comes out clean.
