    Hanging sprinkler pipe to sprinkler pipe - Code infringement, or not?

    I have seen this in a high-rise building...35 floors typical. Pipe hanging to pipe, with bent rods. I know bending rods is forbidden. But pipe to pipe? We know pipe is not structural. Is there any specific code other than 9.2.1.3.1 (NFPA 13-2013) that refers to this type of practice? I...

    Storage Lockers Facilty/Warehouse - Design Criteria

    @ TravisMAck: Yep, that's the truth. I second guessed myself is all, wasn't looking to play with fire so to speak. It's frustrating because the other company is an internationally known company, and I just thought, what do they know that I don't. But then again no ones perfect. So hopefully...

    Storage Lockers Facilty/Warehouse - Design Criteria

    It's roof sprinklers and they've built a mezzanine, so 2 levels of sprinklers. Each unit will have a sprinkler yes. Everything is solid pile really. As TravisMack said Grp.A seems like the best protection. But inside scoop is my competitor is not doing a system overhaul. In this case, an...

    Storage Lockers Facilty/Warehouse - Design Criteria

    Need some input: We have a warehouse facility providing customers with storage lockers (8' x 10' x 8'H). Size of locker area...+- 85,000 sq.ft. My concern is that I can't apply CH.13 Misc. storage (NFPA 13) as we are limited to an area of 4000 sq.ft. max. So I have to move on to Ch.14. If...

    pressure loss for the hose valve

    Hey Travis, Just checked your profile...you have MVP status...all those threads. How the hell do you find the time to answer stupid questions like mine? [wink]

    pressure loss for the hose valve

    Thanks Travis, I always for some reason associated testing when it came to PRVs. I would say I never ran into the situation where we physically had to "prove" the calc by testing the standpipe system. Thanks for the time you spent replying to my question.

    pressure loss for the hose valve

    Travis - What do you mean by "two hose valves at the top of the remote standpipe to facilitate testing"? Are we supposed to prove the 100 psi residual post install?

    Sprinklers in Paint Booths

    Thanks to all who replied. Yes its a prefab booth and I did install heads in exhaust manifolds and stacks. Yes the paper bag is my last resort because the client is very picky. He wants the cleanroom look finishing plates. But as I feared the traditional pendant will have to suffice.

    Sprinklers in Paint Booths

    What type of sprinkler (preferably concealed SR 11.2k) is usually used in a paint booth. Client wants pipe to be concealed, uprights are out of the question. So my dilemma is EH GR2 for paint booth requires 11.2k minimum orifice and I cannot have QR spkrs. Any suggestions?

    Unlimited area sprinkler system sizes for Factory Mutual

    As far as the 10in pipe run goes , its about 100 ft total after my hydraulics were done. Thanks for the feedback folks. I've just completed 2 FM ESFR projects, one of which has a system size of 90,000 ft². My approach to the waterflow switch is replacing it with a Potter pressure switches...

    Unlimited area sprinkler system sizes for Factory Mutual

    Has anyone ever dealt with running 10in. aerial pipe in a warehouse? What are the required hanging methods to support this pipe? Clevis hangers seem like the option, but do we need to trapeze? What about seismic? Thanks Manny
