Raising a steam pipe by 1\"

Raising a steam pipe by 1\"

Hi, we just had the floors retiled in the bathroom, which raised the height by 1". The radiator supply line is now obviously too low. When I tried to unscrew the valve to extend the length, both the valve and the pipe nipple appear to be seized.

I've tried the usual recommendations - propane torch, rust dissolving spray, etc. Nothing. I'm afraid to put too much pressure on it so not to snap the pipe.

I my next option to cut the pipe at the juncture with the valve, and then rethread the riser and take it from there?

Initially I tried to take the 5" tall nipple off that's above the floor surface connected to a threaded union, and replace it with a taller nipple and a new vale. But both are stuck solid, even after I tried all the remdies.

There's about 1" of threading that's visible at the top of the nipple where the valve screws in. I figure I can grind the connection at the very bottom of the valve, and then continue the threads further down the nipple and attach the extender and valve on top of that. Sounds like I'm heading in the right direction.

Not to bust your chops

Did you try to pull the pipe up the one inch you need? You might luck out. Also, search on the Wall, there was a previous thread that covered this exact same topic.
