Bobby, I would suggest that the use of a sleeve depends on the UL Through Penetration System you choose to use for the penetration. Some do not require the use of sleeves.

Can You Live Without Them? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bobby Gillett Sent: Thursday, July 07, 2011 3:57 PM To: [email protected] Subject: Pipe Sleeves We have an existing school we are sprinkling. When we pass through a block wall, non-rated (smoke, fire etc.) we plan on providing clearance or a flex coupling within a foot of the wall on both sides of the wall. Does it say anywhere we have to use sleeves for block walls? We will be using Sch. 10 & 40 pipe as well as CPVC. I can't seem to find anything other than NFPA 13 - 2007 9.3.4.3 "Where clearance is provided by a pipe sleeve.." But nothing requiring one. Thank you in advance.
