Take a look at this pipe:

I need to flip the U-bend on the right hand side round, and take the
flow out into another pipe. Can I unweld any of those joints or are
the absolutely permenent?

If I can't, then the only thing I can think of is to cut the pipe at
the bottom of the short straight length of pipe (there's around 2
inches there to play with) that goes into the right hand side of the U-
bend. Then cut off the U-bend and stop it, and add another U-bend the
other side. Sound ok?

I have always been able to with enough torque. But I wouldn't start a
fight. If its a tight space and I probably can't torque it, I'd just cut
it and buy a new piece. Time is money.
