I recently did a system upgrade of an OH pipe schedule system with 130 SF/head..
Good water supply and a low storage height made it work easily. Back then only hazardous liquids were designed to extra hazard pipe schedule and K8 - 90 SF/head.

Pipe schedule storage occupancy installed per the 1969 edition of NFPA 13. It looks to me that NFPA 231 didn't come out until 1972, meaning storage would have fallen under what I assume was one of the extra hazard curves in NFPA 13 in 1969 (unless I'm missing something or misinterpreting this, I have a copy of neither but would greatly appreciate anyone who may have access sharing). NFPA 13, 2016 edition will allow for the use of a pipe schedule extension of an existing "extra hazard" system per 11.2.2.3(2). I have hydraulically calculated the extension, and it results in huge piping. Which is fine, but there may be an argument by others that pipe schedule would be allowed. Now, I know that it is certainly not the best approach - but that aside - has anyone run into an instance such as this where the pipe schedule extension has been allowed/approved? Thanks to all in advance.
