Remember when you could just tap a flange with a hammer?
Had to replace a section of 6-inch steam line last month, and the old flanges were rusted solid. Back in the day, a few good hits with a sledge would usually break them free. This time, I spent a full eight hours just on those two flanges. Ended up using a torch, a hydraulic puller, and a whole can of penetrating oil. The new guy thought I was crazy for not just cutting them off, but you try explaining heat cycles to a schedule. Anyone else find that the old 'quick fixes' just don't work on modern pipe anymore?
