RE: Building Expansion Joints in NON-seismic Areas

In structural terms and by definition, an expansion joint is not a seismic joint. HOWEVER, they come in different flavors and may be subject to differential movement. Because we're in the heart of seismic country, we have to deal with seismic joints and bracing and flexibility and clearance

Building Expansion Joints in NON-seismic Areas

The only reference to expansion joints I can find in NFPA 13 is within section 9.3 "Protection of piping WHERE SUBJECT TO EARTHQUAKES". So, if I'm not in an area that is subject to earthquakes, can I ignore the building expansion joints? Usually I still add a flexible coupling just to be safe,

RE: standpipes

By definition, a "Branch Line" is piping that connects a single hose connection to a standpipe. Per NFPA 14, §7.6.3, branch piping shall be based on the hydraulic criteria of §7.8 but not smaller than 2½". Since you're at the base of a standpipe and not near the presumed remote area, I'd say

Wall penetrations

Hello Forumites! I'm penetrating some walls with listed thinwall pipe (Eddy Flow). All of the firestop details from Hilti or 3M say the penetrant shall be "Sch.10 or heavier". Is their a detail for listed thinwall? Do I have to upsize to Sch.10 at the wall to penetrate it? Thanks guys... --

RE: [EXTERNAL] Re: Wall penetrations

Just my perception maybe, but a water filled pipe would be much less likely to fail when subjected to fire , regardless of the wall thickness, than a dry (Empty)pipe. Mark at Aero From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Gary Stites Sent:

Re: Wall penetrations

Not any one in particular... they all say "Sch.10 or heavier". I'm just looking for a way to penetrate with thinner wall pipe. On Wed, Aug 9, 2017 at 2:36 PM, Matt Grise wrote: > What hilti product are you looking at? > > > > Matt > > > > > > *From:* Sprinklerforum

Re: Quick-Response Sprinklers in Storage/Extra Hazard

Quoting bcasterl...@fsc-inc.com: Make that 46% increase. If we started with 2500 and reduced to 2000 for using 286F (SR) because of the reasoning, "fewer heads would go off", we would have to go the other direction for QR. 2500x1.3=3250. I did a quick activation comparison with 286F SR

Attic Sprinkler Temps

I'll back Travis up.   Northern US, probably not nearly that hot.  Spent a little time in my attic in Phoenix.  Preferably not in the summer, but 140F to 150 F was typical that time of year. Dwight HavensCity of Phoenix Fire Prevention-Retired___

standpipes

I have a situation where my 6" standpipe is coming into stairwell @ 16' AFF can I drop down 11' (to get to my max 5 AFF) with 2.5" to feed the hose valve on the 1st floor or does it need to drop down 6" with a 2.5" outlet? Thanks in advance Mr. Leyton for your assistance J Rocci
