Code Applicability
(OP)
Where does B31.1 applicability end and B31.9 begin.
I am designing the piping for a water treatment system for boiler feed water and need to know whether B31.1 or B31.9 applies.

RE: Code Applicability
Both of the B31 documents that you have cited have a fairly unambiguous scope written into them. You REALLY need to read the documents. B31.9 is Building Services Piping and its scope limits it to relatively low pressures and temperatures, limited selection of materials and limited pipe sizes.
RE: Code Applicability
It is certainly confusing when one is trying to establish the "Code of Record" for a project.
For the exact same water treatment system located in a chemical plant, a case could be made to design to the ASME B31.3 code....
Any others have comments on this issue ????
My opinion only...
