Two steam radiators piped in series

I have a client who is asking me to add a radiator within his bedroom as the current radiator which is located on an opposite wall of a very large bedroom is not adequately heating his space in the giant walk-in closet. There is a radiator already located in there I’m curious if there’s any negative implications if I were to remove the 2 inch plug at the bottom of the radiator located in the closet and extend a pipe utilizing proper pitch into the next room which would be his bedroom and add a second radiator ultimately placing these radiators piped in a series fashion is that possible

    Forget it- it won't work. @DanHolohan covers this in his excellent book "The Lost Art of Steam Heating".

    Curious, could there be an arrangement utilizing a single supply valve where they could be joined in parallel so to speak? Basically split at the inlet valve, piped around behind the first radiator with slope to the second radiator which would have to be set on some amount of blocks to maintain pitch on the supply pipe. I have never seen it but if the current supply pipe size is large enough to support the two radiators could it work?

    Yes that could be made to work, @dabrakeman . The trick — I'm assuming single pipe here — would be to get the balance right, and might take some fiddling with the vents. The other thing to watch out for would be not exceeding the EDR capacity of the riser and any runouts
