I picked up a set of pipes and one has a dent in it. Pretty good one too. The guy had been running them but i was going to try and fix it.
I was told there is a trick, plug the end, pressurize it and heat up the dent and it should pop out. Anyone tried this? Got any other ideas? Figured i would just cut it and reweld a peice in but any non evasive procedures would be considered first. I also herd of filling it with water and freezing it. Never tried it though.
