radiator nipples

100 year old cast iron radiators, trying to add TRV's. Does anyone have a trick to get the old nipples out when the inner spud nipples just snap off. Most are 1.5" size pipes.

    I cut the nut off with a buzz grinder, insert my spud wrench, and use a pipe wrench. The spud wrench stops the brass tailpiece from collapsing and you can usually get enough torque to get it to spin out...also spray on some pipe-break free stuff...

    Rad nipples

    Also if nipples break off or wrench won't do it, cut a small pie shaped piece out with a sawzall and very fine tooth blade. Take out piece and rest can be extracted with a hammer and chisel.Careful not to cut into the radiator threads. Good luck.
