Testing an Expansive Firewall Pipe Collar (Intumescent Graphite)

- Here's a quick follow up to my last video about intercalated graphite and it's use in intumescent, fire resistant products (seen here: • Fireproof Expanding Gr... ). This pipe collar uses strips of compressed expandable graphite flake with a flexible binder to wrap around pipes and seal them off in case of fire. Pretty neat.
Thanks to Structure Tech Home Inspections for allowing me to use their footage of a successful collar test. Their video can be seen here: • Not a flamethrower tes...

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.
Anyway that type of system should be much more fire-resistant than this, also more reliable and cheap.
So it worked.
Well it works , just needs calibration
I just noticed that I was trying to limit my breathing because of the burning plastic in the video, funny the way our body works
It's saddening to contemplate the current state of grammar in most modern Indo-European languages.

What do you mean?
hey thats definitely not a bad reaction lol
Could be worst, if I smell cigarette smoke my lungs instantly constrict making it harder to breath than normal (I have asthma). Might help reduce inhalation of the poison (as if I wasn't inhaling a ton of other poisons at my factory job).
Had the same moment in the newest video, at the nano particles part
I think it's important to have an enclosed "room" to perform this test in, because there the temperature will increase a lot more quickly and uniformly than with just the fire below.
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.
Ok, a video of it crushing a cast iron pipe is one I'd like to see ;-)
Each time I see a Night Hawk In Light video, I get so excited. I really love your work. There is so much enthusiasm in your videos, and they are relatable and realistic. Great content, thank you.
Thanks!
I love that you share the progress more frequently with us 👍
Great you showed this in action, as this shows where the expansible graphite works really well in the right sort of application.
Oh nice! real world application already in use! love it!
i think this was a decent test, even in not ideal setup it still had some effect, may make a large difference in survival time
Especially when you consider that generally pipes carrying things through walls are typically sized just large enough to comfortably carry what needs to pass through it, so such a large empty pipe is extremely unrealistic.
People find all sorts of clever uses for every invention.
You have a very interesting vocals in this. Very raw and like your standing next to me. I like it. Really brings the humanity with the video making. What's enjoyed your videos. Look forward to more. 👍🤘🏿🤘🤘🏿
I learned something new. Never knew these existed prior. Thanks for sharing as always!
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... :)
Thanks for the video. I now understand how fire collar works and am able to see it so I can have a deeper understanding.

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.
Been subbed since I saw you on Instructables making a dart gun from a lighter and a pipe about 10 years ago or so! (I think that's the first I saw anyways) Glad to see you still uploading and I always look forward to your videos! Keep up the great work!

I think this was a successful test because it showed the forces and that such a fire prevention must be properly installed in order to be effective.

I specified a bunch of these from Hilti on a 5 story wood frame over 1 story of concrete 324 unit apartment complex. Needed one for every pipe penetration through a rated assembly. It was required to use pvc instead of cast iron pipes. Cool to see!!!

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 .
Thanks for the info, I should have looked more carefully at the data sheet before testing.
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.
You look and sound so kind and nice , also videos are incredibly interesting

I really think night hawk in light is the new king of random and I very much appreciate it. I believe while some of your videos are much more in depth and less “fun“ your channel is very similar to what the king of random was at its prime. Not what it is now by far but what it could’ve been.
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.

Nice video by the way!

Seems like the manufacturer needs to include those fingerlike metal projections on both sides to ensure the expansion is properly directed under most circumstances.
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.
This comment section surprised me
Man i really wouldn’t want to rely on this device for my fire stopping
If the pipe IS carrying the fire through it this test is great
nice and add the putty on the pipe say 3" away from wall to zone heat it
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.
Shouldn't you be playing cluster truck?
Check out some fire science. Any enclose space becomes very hot uniformly. Especially attic spaces where you are likely to find something like this
If the graphite is placed inside the pipe, it would have sealed the inside better I guess. Leaves one question: why not seal the pipe with rock wool or glass wool by default?
This is an interesting video of an ad hoc test, but there are a number of factors that have led to the unsatisfactory operation of the collar. In real life (and in a standard fire test regime), the supporting construction would be far more robust that a thin sheet of metal, this would give a better seal between the collar and the wall, and would also not deform as rapidly or to the same extent. The three fixings would be perfectly adequate on a dry wall or brick wall construction. The product will have detail instructions on both how to install the item, and under what circumstances it will provide the advertised fire performance. The world of passive fire protection is often a victim of marketing BS, and the principle of caveat emptor should always be applied.

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

2:20 I can smell his whole area.... Through my screen!
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?
They make "pillow" versions of this that are meant to go inside vents.
Don't feel bad . You're not the only guy with a short pipe ...
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.
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.
Reminds me of when I eat spicy food
😂
I feel like this product would need an inner pyrotechnic charge to evenly spread heat fast in the mateiral, similar to what the fire extinguisher balls covered by smarter everyday were using.
Hey nice ! Could you do some experiments around thermochemical heat storage ? Zeolite, Calcium chloride and sodium acetate are pretty basic materials and their diy use is under explored ! We could for instance replace water with one of them in solar water heaters ; )
Yes that might be something I look into one day. I have some ideas
It's unrelated to the video, but it'd be so awesome if you could make a diy microscope that's more than the laser pointer lens one's, common on UA-cam.

Adding a single sheet of the same as an interior liner (inside the pipe), would definitely close the pipe and encase the wires.
Feedback been appreciated, send a direct message something Special for you.
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.
Wow
I would have thought this would have been for a thin metal pipe
Interesting
I think another factor is a lack of anything flowing through it which would have acted like a coolant and stopped the pipe from burning

Mose bird cameo please!
Any updates on the cooling infrared paint? Apologies if I missed it.
That'll be a summer project. I've got lots of things I've been working on for that one
Someone think extinguish fire with graphite is good idea? Metalsmiths approve
First let me say love you're channel , second I know it has nothing to do with this subject ( very cool by the way) but I wanted to ask if you know of anything that blocks magnetic attraction besides distance, if you no what I'm trying to say ? Like if you have two 1inch square magnets say 1" apart and let go of them they will slam together, is there anything I don't know let's say lead for instance 1/2" thick between them stop them from moving at all I know lead will not but is there anything that will that you know if ?
No there's nothing that blocks magnetism. You can bend magnetic fields but not block them.
talking about hole that shape and using the word "tumescent" is bring out some kind of feeling...
Could it be that the other fire restrictive feature is sealing the hole which the pipe goes through? This way it is buying time and restricting the fire to other side of the wall.

I thought that placing expandable graphite inside the pipe in order to prevent propagation of flames makes much more sense and works quicker. Having the collar would be the backup plan.
That's a good idea. They make "pillows" that expand for that sort of purpose in vents.
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.
Wouldn't a similar design but on the inside be better? That way it could function even with metallic pipes.
They have pillows of this stuff that are meant to go inside larger vents for that purpose
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.
This is for conduit
Good one!
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)
Cast iron
Pipe would work
You should check out Hilti fire stop solutions. They have the best on the market.
Have been watching your channel for few years now...as you grow older you seem to resemble Chuck Norris.

what about putting it on the inside of the pipe instead
Yes that's also done sometimes
Risky fleshlight
also for thin sheet metal pipe sections, but a hydraulic press would crush any pipe, tho
thin sheet metal pipe would be better, it would not burn itself
Not sure why but this video didn't show up on my feed or sub video list even though I'm subbed.
This video is having problems. UA-cam has only showed it to about 20% as many people as normal, although subscribers have mostly seen it.
I think it would be much more efficient if the collar was put inside the pipe. That way it does not need to crush the pipe, just fill the space.
They make pillows of the same material for that purpose. That's what you would use in an opening bigger than 4"
Wonder if this material could make safes more fire resistant.. most are rated for 30 minutes to an hour.. I always imagined fire proof safes still standing with the chimney in a worst case scenario!!!
Look up intumescent paint. I think it would be excellent to add fire resistance to a safe.
mix your new expanding grapite into starlight see if both are better or worse
