Pipe Sleeve That Can Be Installed After the Pipe?

4/22/2024

Does anyone know of a sleeve product that can be installed AFTER pipe installation without backing out the pipe?

The underlying issue is that I have a project with seismic requirements (for extra clearance at penetrations) that has many fire rated walls. Basic pipe sleeves with extra large clearance filled with fire caulk is our typical situation, but if a sleeve gets missed during rough-in, we're hoping to use something after that fact.

So either looking for a split sleeve of some type, OR a way to fire caulk a 2 hour rated gypsum wall with extra large clearance per NFPA 13-2016 section 9.3.4.3.

Thanks in advance.

No idea if this is actually what you're looking for and I didn't check what it's actually listed for but:

"External Mount Split Wall Sleeves
The External Mount Split Wall Sleeve is designed for sealing pipe penetrations through walls, floors, and ceilings in atypical scenarios. This wall sleeve is unique in that it can be installed after cement has been poured, whether that is 5 days or even 5 years. It also installs quickly and easily around existing piping in retrofit projects."

Talk to your firestop rep (Hilti, 3M), explain your wall (materials/thickness), hole diameter, split sleeve, and the rating and have them use an existing system or create an Engineering Judgement for the project to follow.

Typically we just get some galvanized rolled with a lock seam for any post install-install......then use the Standard or an EJ system for the rating.

The use of split-sleeves is what I have seen used in this application.

Many UL listings allow a sleeve made of sheet steel that's rolled up and inserted into the opening. They often protrude from the wall a bit, and are held in shape by worm gears. Much like Dan's, but without the lock seam.

I always did pipe sleeve for seismic— solid usually galvanized, then I gave the drywall foreman a hundred bucks a t beginning of drywall to set, and a hundred more when job was done.
For strays, of sleeves missed, I d use a dw saw, or a circle cutter or zip saw to cut around the pipe, use split sleeves, split pipe sleeves if schd 40 specs, place around pipe, wire at each end , once around pipe outside the wall and slide into the wall, when possible , then hilti 2hr caulk.
Plasma cutter in shop for splitting the schd 40. If galv pipe, cutter must use an air pressured respirator for toxic fumes. Any shop has that capability.
If split sleeves are ok, usually only 30 minute rating, so I d have to make a large hole and 4 sleeves—- only tried that once, never again.

I think I've seen some listed split sleeves

What about using Hilti fire collars? This would eliminate the need for caulking while addressing the large pass through holes. While fire collars aren’t typically required for water-filled metallic pipe, it may be easier in the long run. I have been on projects where it was actually cheaper to use the fire collars versus large amounts of fire caulk applied correctly. Just my opinion.
