Mixing pipe.....
(OP)
I just came from a Building , in that building the contractor used a mix of galvanized and black pipe for an area. The system is a wet pipe system ordinary hazard(group 2). I have never seen the mix of regular black and galvanize pipe is this prohibit by the code. I was not able to find it in NFPA 13.

It is a military base. I know the newest UFC do not allow galvanize pipe at all. but this building was contracted few years ago.

At this point I'm not really concern, the building was accepted like that by someone else. I have never seen that done anywhere else, that ‘s what pick my curiosity. I was thinking in the same line of what peddarin said. Is this a common practice?
