Removing Old Steam Radiators

I have replaced my old gas boiler/steam radiaors system in my 1924 home. I have pulled the radiator out of my masterbedroom when laying carpet. When the On/Off Valve was removed it bent up the vertical pipe running through the floor and to the supply pipe. The plumber could not, or would not, remove the vertical pipe. I have tried to turn the pipe, but it is stuck. Does anyone have any suggestions about removing these vertical pipes?

    You'd probably have to cut it

    which might be a problem if the pipe is concealed on the first floor.

    Did you just replace the boiler, or are you trying to completely remove the old system? If the latter, what did you replace it with? If you put in scorched-air, you won't be comfortable at all. In that case you could use the ducts for A/C, and fix the steam system.

    You aren't going to get those off, my friend....................

    without either crushing the pipe or busting the cast fitting below. You can try to get it off with some big wrenches but don't hurt yourself..you could try some heat on the fitting if you can get at it but don't burn house down....or you can cut it and thread it in place...get a pro in there save yourself alot of trouble.

    It can be cut.

    The cut off and thread response will work if you have space for the cutter and die. What I do is to cut with a small grinder and install an expandable plug and leave it there or if pressue is and issue drive in a steel pin and weld it. The welding option calls for very careful fire watch.
