I have seen this many times where a Sprinkler Pipe passes thru duct work.
Primarily on existing older projects, Installed before I started designing
30 plus years ago.
Is this practiced allowed? I don't find any reference to it in NFPA 13.
This just happened over the weekend when duct work came through a wall and
instead of offsetting down to get past an existing sprinkler branch line
pipe the duct maintained elevation and was installed around the pipe.
