Not that I am aware. "Large drop" sprinklers had a requirement for galvanized pipe with dry and pre-action systems.

Is there somewhere it states the pipe and fittings are to be corrosion resistant (ex. Galv.)? I thought somewhere it stated for preact it had to be regardless, but I can't find that either. Maybe I'm pulling an old spec from a project out of my brain as the last two I've done have required galv. piping per the spec book. Bobby Gillett Sr. Project Manager Key Fire Protection, Inc.
