PSA: We stopped using a come-along on those tight flange fits and it cut our time in half
We were fighting a 24-inch steam line flange in a plant in Toledo last month, and the bolts just would not line up. The old way was to crank on a come-along for an hour, fighting it. My lead said to try heating just the bolt holes on the loose flange with a rosebud, not the whole thing. We got it to about 400 degrees, tapped it with a beater, and the bolts dropped right in. Whole job took maybe 15 minutes. Anyone got a different trick for stubborn flanges that doesn't involve beating them to death?
