Converting High Pressure Steam to Low Pressure Steam

Hi, I'm new to the site. I did browse around the threads to see if this topic was discussed but didn't find anything, but my apologies if it already was.
I work at a large commercial facility that produces our own high pressure steam (100 psi) to provide the facility with heat and hot water. That same boiler also provides steam to a neighboring facility via an underground high pressure line. Recently this high pressure line started leaking and we're planning on replacing it. What would be involved to provide a temporary low pressure steam portable boiler at that neighboring facility (preferably a low pressure boiler to reduce costs) during the replacement underground line? Would a low pressure steam boiler feeding after the PRV be possible since I believe most of the coils use ~5psi.
Any insight would be appreciated. Thank you in advance.

    First off: I am not an expert at this. By any means. Eventually someone will come along who is...

    That said, it seems to me that it would be quite feasible, assuming that you really don't need more than about 5 psi. Most of the various boilers in use for heating can handle that pressure without difficulty. You will need to make a careful survey of the actual load, of course, for sizing. The only area which might get interesting would be handling condensate return, but that can be done.

    Rent a mobile boiler.

    Yes, a rental boiler (low pressure steam) will work fine as long as it's connected downstream of your prv. No issues with it at all.
