Jeez I feel like I should be 20 yrs older for campfire stories. Back before there were 8" dry-pipe valves, we'd routinely tee to a pair and then bring em back together, usually with 8" but if this was a BIG system, then 10" wouldn't cause us to bat an eye.
As for design criteria, would have been completely up to what was out there and what insurance carrier might have been involved, what AE firm, etc. And either everyone else seemed to know what they were doing on jobs of that nature, or I was still clueless and didn't know myself. But in general, FM or FIA/OIA/IRI or similar HPR carrier would know what to tell us to do. Working at ASCOA, if they didn't our SH contract reps, who generally handled these, were top flight. glc -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Phelps, Mark Sent: Monday, February 08, 2010 1:11 PM To: [email protected] Subject: RE: Strange piping arrangement and/or it could be for maximum reliability.
