In Reply to: TWO STEAM BOILERS WITH DIFFERENT MAWP posted by ROY REYES on December 14, 2010 at 14:05:39:
: Here is the scenario, one of our customers has already installed and running a steam boiler with MAWP of 150 PSI, currently running at 50 PSI.
: The customer wants to install a low pressure steam boiler MAWP 15 PSI and have this one as a back up in case the other one fails; they want to pipe it to the same steam header using isolation steam valves.
: I have been reading the Texas boiler law and cannot seem to find something for sure, it does not sound like it will meet code requirements.
: Any information will be greatly appreciated.
