Intentional filling of a scuba tank above maximum tested pressure. Explosion within the safety box of the German compressor manufacturer Lenhardt & Wagner.
A couple of things! First, i hope this shows people that although a scuba tank exploding is not common, the results are disastrous! Notice that the door after the test was dislocated. You can go back to the unit before and after the test and see how the explosion dislocated the door. Imagine that tank exploding on the back of a human (that's one negative way to get a "ripped" body ☹)! Second, this device works! It is a safety device meant to stop people from dying or a boat from being destroyed. It does the job! Yay! Be careful people. Dive well!
It is a safety device. ... The fact is no one would be injured or killed using this. That is a good thing. No one complains that the airbag in their car only works once. It only has to work once to be worth it.
Exploding scuba tanks is an extremely rare event. But catastrophic when it happens when filling with a gas. Testing is done with water if a cilinder fails it just cracks and leaks water. Filling tanks is best done behind a concrete wall. A small water bath doesn’t do much about the explosion but helps to cool the tanks while filling.
The biggest take away from all of this? The "Tick tick tick tick" sound before it blew. I've heard that sound before BLEVEs (boiling liquid expanding vapour explosions).
The experiment is not meticulously presented: cylinder mayerial, cylinder rating, temperature. A video camera inside would have been great. I think it was a steel tank for firefighters with a normat pressure of 300 psi tested at 800.
Firstly and foremost. What was the tank rated to? And what was the actual reading of the pressure measurement? For all who may be interested, the "rated pressure of the tank" indicates at what pressure the air receiver tank can safely handle to operate efficiently without putting itself or anyone’s safety in danger. And then, and after all - yes!!! WOW! And KaBooM! And once again, WOW!
I was down in Cozumel and of course I was using their tanks they were pre filled before our dive and it made me a little nervous when I hooked up to my tank it was filled to 3600 pounds I've never seen a SCUBA tank that overfilled and it was a typical aluminum 80
that isn't actually an uncommon practice, especially in the cave diving world people want that little bit of extra air and will fill to 3600 on AL80''s and sometimes to 4000 on catalina's, but if you think about it, an AL80 is rated for 3000psi but every 5 years you should have it hydro'd where they'll fill it to 3/5 the working pressure, so 3000 becomes 5000. they don't burst hardly ever on those so 3600 every now and then isn't bad, also a tank generates heat when filled, so if they didn't have it submerged in water that 3600 will cool down to 3300 or even 3000 once it's given time to set out.
I dont understand this as when the one time I recharged air bottles when I was employed with the fire department they claimed the system was designed not to explode!!!
344 bar 5200psi only? Was this a low pressure tank because my understanding that the 3000psi standard aluminum tanks are hydro tested at 5/3 working pressure meaning 5000 psi, abd they generally don"t break. What was the working ptressure of these tanks please?
All well and good but you can pressure test scuba tanks in a large horse trough sized steel container with an open top filled with water and safely do the same thing at 1/50th the price you charge for this container.
The pressure test for an tank is conducted by filling the tank with water, and pumping more water into it. since water is incompressible, the pressure rises very quickly for not much difference in the volume of water: So if the tank fails, it just cracks. Pressure test it with compressed air or a gas and you are creating a giant grenade.
It's a fire extinguisher, a regular CO2 extinguisher operates at about 55 bar, this was filled _way_ beyond its normal operating pressure, so I'd say that it's actually _quite_ safe, for a fire extinguisher.
Its exploded on 320 bar???? What the fuck i always fill my tank right around 310 bar at home.. almost nearly to the exploding line right beside my ass...
The boxes that we make like this go on fire fighting equipment and rescue boats. They have to still be in working order after a tank failure. The box in this video didn't meet that standard.
Not very impressed with that safety box, probably cost tens of thousands of dollars and was only good for one test... Step your game up Lenhardt & Wagner.
the box itself cost $300 US. Not even close to what you suggest. Additional it is a performance test of a completed system- required by US, Canadian and Euro safety and manufacturing standards. What kind of troll are you: from a competitor or just stupid?
That's highly unlikely that that box cost $300. Maybe the metal cost $300, but add in the machining and it's more. Not counting the gauges and other hardware. Way over $300.
Heard about a dive instructor that passed away yesterday and it is believed that his compressed air cylinder exploded while diving. I dont even want to imagine what probably happened 😖😖

Very impressive safety tool. I have witnessed air tank explosions. The metal can rip a man into... bleed out in seconds!
I love how the metal being stressed ticks like an actual bomb (which it basically is at that point).
how did that happen？

what do you mean? what is a safety device? what is the good thing? what do you mean at all?
Eric Brooksby l
too bad you cant read
Would love to know the thought process that brought you to this analogy and correlation, because on the surface it's a real stretch.
Eric Brooksby Lol that..alright not really lol. I’m with the guy who says that’s a damn stretch.

Who else was thinking "Smile you S.O.B" before it went off?
The biggest take away from all of this? The "Tick tick tick tick" sound before it blew. I've heard that sound before BLEVEs (boiling liquid expanding vapour explosions).
You know that's just a sound effect added for the video...🙄
Such applause as if she was supposed to fly to the moon😂😂😂
Такие аплодисменты, как будто она на луну должна была полететь😂😂😂😂
And that's why your tank valve should have a burst disk and regular visual inspections and hydro testing
If I am correct, burst disks are not allowed on scuba tanks in The Netherlands
@@nielsvanvelzen I have no idea what the Netherlands do... But Burst discs are used in North America
Gutes Video !!!! Solche Füll Boxen sollten zur Pflicht werden
This is awesome
Thank you.
Nice. I'd say it's well worth it. It only has to work once.
2:49 Iron Man´s new suit.
Filling tanks submerged in a large water tank made of brick is how its done here, the explosions I have heard about were never bad.
It took that like a champ!!!
The experiment is not meticulously presented: cylinder mayerial, cylinder rating, temperature. A video camera inside would have been great. I think it was a steel tank for firefighters with a normat pressure of 300 psi tested at 800.
A tank probably rated for 150-160 bar exploding at probably 315-320 bar I’d say is pretty reasonable! Nice blast cabinet tho!
What was the tank rated to? 3000psi? They are tested at 1.5x nominal so 4500psi shouldn't be a problem
1:38 it only blows once..

maybe a SPG error?

This is a very suspenseful video..! lol..
Fire extinguisher not a scuba tank. That's why it blew at 320 bar. A scuba tank can handle that pressure easy. Nice try.
Что за одноразовый сейф?
I dont understand this as when the one time I recharged air bottles when I was employed with the fire department they claimed the system was designed not to explode!!!
so at what pressure it exploded?
320 bar = 4641 PSI.
How many bar till boom?
Approx 344 bar.
344 bar 5200psi only? Was this a low pressure tank because my understanding that the 3000psi standard aluminum tanks are hydro tested at 5/3 working pressure meaning 5000 psi, abd they generally don"t break. What was the working ptressure of these tanks please?
These tanks do not look like scuba tanks, but a CO2 extinguisher tanks. I think these have somewhat lower operating pressure.
@@Sixta16 a co2 extinguisher. Most extinguishers are 1600psi. I think 110bar.

Hydros must be conducted every twelve months in New Zealand, and Australia, by law.
Not easy to explode. It can be explode above 300 bar...
Those things can level a house and kill everyone in it.
What can? A compressed air tank?
@@sherifnabil9663 scuba tanks are filled to 4,000 PSI, if it were to burst, it would be devastating.
Aww.........#tankslivesmatter
racist much?
German safety box that was wrecked by the explosion 🤣
What the fuck is blowups over 318 bar,
I fill my pcp carbon fiber tank about 330 bar,
Right on it tested over 450 bar
this tank is so unsafe
It's a fire extinguisher, a regular CO2 extinguisher operates at about 55 bar, this was filled _way_ beyond its normal operating pressure, so I'd say that it's actually _quite_ safe, for a fire extinguisher.
Чтоб сломать карбоновый 300барный баллон, надо создать 1200бар
Its exploded on 320 bar???? What the fuck i always fill my tank right around 310 bar at home.. almost nearly to the exploding line right beside my ass...
Kamran Pipekesh They can explode at 300, as others have stated as well.
The boxes that we make like this go on fire fighting equipment and rescue boats. They have to still be in working order after a tank failure. The box in this video didn't meet that standard.
So you think its a normal thing for the bottles to explode and its such a regular thing you would need a second one?
Not very impressed with that safety box, probably cost tens of thousands of dollars and was only good for one test... Step your game up Lenhardt & Wagner.
the box itself cost $300 US. Not even close to what you suggest. Additional it is a performance test of a completed system- required by US, Canadian and Euro safety and manufacturing standards.
What kind of troll are you: from a competitor or just stupid?
what was the the working pressure of those tank? 3000psi?
a normal scuba tank goes 3000 psi.
Some firefighting SCBA tanks go 4500
usually scuba tanks fail at 8000+ psi or 550+ bar not so low like this one.
That's highly unlikely that that box cost $300. Maybe the metal cost $300, but add in the machining and it's more. Not counting the gauges and other hardware. Way over $300.
Heard about a dive instructor that passed away yesterday and it is believed that his compressed air cylinder exploded while diving. I dont even want to imagine what probably happened 😖😖
