Splitting a Steam Radiator

The sections connect with smooth, dual-tapered push nipples and seal strictly via metal-to-metal contact.

    Remove Radiator sections how to ?

    I have a steamRadiator (1pipe) that I am moving.
    It will be too long and I am looking at being able
    to remove 3 of the 11 sections. It was build by
    UsRadCorp the house is 80 yrs old.

    My understanding is to remove Rods then use wooden wedges
    to 'split/seperate' the sections. I am not sure about the seals between section, what they are made of, would they be available. Is there any other concerns ishould be made aware of
    Thanks !

    you'll likely need...

    a BIG hammer. Wooden wedges will work, at less risk of breaking stuff (it's cast iron, remember, and brittle) but you may need to go to steel.

    As noted, the seal between sections is supposed to be a beautifully fitted (those old guys were craftsmen!) 'push nipple'. However... you may find that the nipples are pretty rotted. All is not lost: I have had excellent results using the red RTV sealant for engines to create a new seal between the sections when I put them back together and the nipples are shot.

    Yes, you can get new nipples. But why?
