Hey Patriot.....I thought of something today that I've run into in the past. If you have a lot of big water pipes, some may be ductile iron. I ran into some on a water tank project and had a tough time with them. They looked cast, but I couldn't break them with a backhoe. I tried a torch, but it only heated until red, but would never liquefy so I could cut it. There was one 24" pipe that I had to cut so I used a demo saw with diamond blades and it took two blades to cut it twice.
The rest of the pipes I could get out in 20 foot sections so I loaded them whole. I found out later (after the job) that I could have used a chain pipe cutter with cutting wheels on it like a copper tubing cutter. You wrap the chain around the pipe, tighten it and score the pipe for a smooth break. I think some of the cutting tools you have in your other thread might have worked also, maybe even a hotter torch. Maybe someone else has more experience with this than I do.
If you run into this stuff, it can be a pain, but it can be cut. If you need to cut it smooth to reuse, the chain pipe cutter could do the trick.
