I managed a hangar and we used fusible links to create a spring-loaded latch that would snap closed if the temperature got above a pre-set level and melted the 'fuse' holding the hatch open. That was the plan. That said, they installed these links in heating ducts and they all snapped closed the first time we used the heat. Best-laid plans of architects and building codes.

Great you showed this in action, as this shows where the expansible graphite works really well in the right sort of application.

The company I work for we Install collars like this but Hilti branded. Depending on the penetration type (ie. Brick, concrete, gypsum, drywall, etc.) You require different methods of installation. For concrete as an rough example you would need to first surround it with an intumescent caulk (ex. Hilti FSOne MAX) with a minimum of 1/4inch into the penetration of the wall and surrounding the circumference of the pipe making sure full contact is made between the pipe, the caulk and the wall (like using silicone around a sink, tub or window as a rough example). Once the intumescent caulking is applied you then place the collar (ie Hilti CP 643 Firestop collar) around said pipe making sure it's flat against the concrete. When they are installed correctly together they work amazing at doing the job they are designed for. The issue with putting the fire where you have it is almost exactly like what you stated, your pipe was too short allowing the fire to basically melt the open end. The room itself heats up causing the collar to work more effectively than just placing a flame directly on it. Typically where these collars are used they're often hidden out of sight, that is why most people have never noticed them before or even heard about them. Just wait until you find out about intumescent paints and mortar. Hilti (and a few other companies, Hilti being the easiest for the average Joe to obtain) make some intumescent paints you would definitely have fun with. Edit: **for where I'm located** PVC and cast iron pipes are generally drains PEX or copper is often used for water supply Cables are typically ran with conduit or through a steel pipe sleeve through the wall Nearly everything penetrating a fire rated wall/assembly (for us provided by a detail) almost always has an intumescent caulk installed around it. PVC and a few other pipes will have a collar installed as well. We have tested (to prove to a few clients) FS-One MAX on a 4" cast pipe and it literally shattered it closing off the hole when installed properly to a detail as per specifications.

HELL YEAH! SCIENCE! i am wondering however if braided tubes could maybe do something similar, maybe use the expansion to melt the braids closed with the heat a bit faster.

Since the rules changed on our mains distribution boxes (aka fusebox, or breaker box over there) here in the UK to require the fitting of metal boxes instead of plastic in new or replacement installations, the use of intumescent sealants have become a requirement to keep any potential fires in the box from getting out into wall cavities or onto the wooden board most of our electrickeries tend to be distributed from... :)

Don't feel bad . You're not the only guy with a short pipe ...

IF the collar were bound by a metal collar - it would encourage more even heating, as well as direct the intumescence inwards, rather than leaking randomly.. (iseas for manufacturers of mounting hardware.

Interesting content! I see potential failures in the test for reasons NightHawk didn't mention. In video-test the fire had a strong one-sided source of the heat - the fire below the test site. In an actual structural fire, I believe the temperature around the entire pipe fixture would be much more uniform, and therefor firewall pipe collar would likely behave more uniformly. In all other cases, this was interesting and informative. EDIT: Ahh, there was mention of "unidirectional fire" fire at end. Hit nail-on-head.

If the pipe IS carrying the fire through it this test is great

Man i really wouldn’t want to rely on this device for my fire stopping

Wow

Seems like the manufacturer needs to include those fingerlike metal projections on both sides to ensure the expansion is properly directed under most circumstances.

Interesting

I actually work in one of the bigger fire Testing laboratories in Europe. Those kinds of Collars are usually used on Drywall or similar products. The typical setup for a wall in testing is 2 Sheets of 12,5 mm to 15 mm drywall on either side with stone or glass wool ( more commonly Stonewool) in between. Those Collars are very sensitive to the correct Thickness of the pipe and material. The pipe Thickness of this pipe was on the bigger side for Polyethylene. Did you check the data Sheets for this product if it allows for this Polymer in this thickness? They are also very sensitive about the structural integrity of the wall. Also they are commonly used in Pairs. One collar on either side of the wall. You are correct about the length of the Pipes. Typically they are Tested in lengths of at least a meter form the wall either side while they are open on both sides. If you have questions about fire Testing feel free to contact me .

Not to mention that its not usual to have a 12" piece of pipe sticking through a penetration like in the video, the pipe run is going to be continuous. The intumisent material is meant to ensure the penetration completely seals off during the fire.

This comment section surprised me

I wonder if some "back snake firework" could do that job. This expands a lot so it could act as a nice insulation against fire. Unless it's too fragile and collapses.

In his previous video he shows exactly that. A "putty" with expanding graphite used to insulate electrical boxes during/due to fire. Yes, this expanded graphite is perhaps the best insulator for that application.

These are only rated for ABS or PVC pipe, so maybe they perform differently with the HDPE pipe?

Reminds me of when I eat spicy food

A more effective way to utilize this would be using a damper. The expanding graphite would have to be sold as part of a kit that would mount through the wall and have other pipes or even metal conduit attached to it. This system would have a V notch blade that could cut any cables as it rises to block off the hole. Because it is a secure unit, the graphite would be completely contained under the blade and would not be able to leak out, giving maximum pressure. I suppose they could be sold in 1 and 2 damper configurations to offer protections from both sides if desired, but anything passing to an external wall or room with superior fire suppression like the Halon systems in a bank vault would only need protection on the one side.

Seems like you'll only ever see compression from one side of a pipe. And that 90% of real world circumstances would find that heat sourced below. Which makes me think setting a 50% volume-filled standard for the pipe, along with a more rigidly mounted half-collar (instead of a full ring) would maximize the benefit, while minimizing material waste. Properly designed, a second half-collar could be attached to make a full ring, optionally.

Check out some fire science. Any enclose space becomes very hot uniformly. Especially attic spaces where you are likely to find something like this

Could this be used to create a passive (no external power) Domestic fire door closer. ie the expanding carbon provides both insulation & motive force to close fire shutters. Activated by the heat of a fire.

Wow and thank you! (being one of those commentators) What would happen if you have the collar inside the pipe? If is a metal pass-trough pipe, maybe it can simply block it? Standard procedure when going between fire sections in buildings in Sweden is yo use a glas fibre reinforced cement. But for less regulated pipes, maybe having it inside would prevent spread?

nice and add the putty on the pipe say 3" away from wall to zone heat it

How would it behave if the pipe is filled with e.g. water? I would assume that the collar ist mainly to prevent smoke and flames sneaking in between wall and pipe into the next room since a filled pipe would stay stable way longer.

Seems like an insert inside the pipe would allow for faster and more complete restriction. Obviously for some applications this wouldn’t work. The application you showed would be much easier to retrofit.

I i guess it really depends on the definition of its purpose... What exactly is it designed to do... act as a 1 hour fire stop? (something else?) Seems like this stuff while partially useful, wouldn't actually work well enough to stop a fire in time. I can't say this for certain, but, without a slightly better test design, my view is that it doesn't do the job well enough to stop a fire (at least for that size of pipe as demonstrated)

This video is having problems. KZread has only showed it to about 20% as many people as normal, although subscribers have mostly seen it.

Good video. But are you sure that the collar is supposed to close off the pipe, and not the opening through the barrier? A pipe would be sealed on either side to handle gas or liquid, and a conduit would be unlikely to be completely open, and more likely to be closed off with metal plate or another fire seal. Heating a fluid in a structurally compromised pipe, with an added restriction, might be more of a disaster than leaving it alone.
