500 Ton Hydraulic Press vs Oxygen Tank | How Much Pressure Can It Take?

Added: 2026-04-28

[00:00:02]Judging by the thumbnail of this video, there will be a big bang today.

[00:00:08]We will be testing the durability of a 1 L oxygen cylinder made in the USSR.

[00:00:16]The working pressure in such cylinders is about 200 atmospheres and they [music] withstand up to 500 before bursting.

[00:00:25]The explosive force of such a cylinder is comparable to that of a hand grenade.

[00:00:32]We will be testing such a cylinder not filled with air or oxygen, but filled with water.

[00:00:39]And as it turned out, filling it with water is not that easy.

[00:00:43]So, what's the easiest way to fill it with water? It would seem you just unscrew the valve, pour in the water, and screw it back on. But the thing is, with these tanks, it's practically impossible to unscrew the valve without damaging it. After partially disassembling the valve, I found a small hole through which you can fill the tank with water using a syringe and needle.

[00:01:11]True, it's a former war sitting on your second. There are those not very fast.

[00:01:16]It took 1 and 1/2 hours to fill two such tanks. Yes, today we will test two such tanks.

[00:01:25]But what first, let's conduct an experiment with small already used carbon dioxide cartridges.

[00:01:33]When water freezes, turning into ice, it expands in volume.

[00:01:40]And as a rule, this leads to damage to the container in which it is located.

[00:01:48]Defrosted heating radiators, engines, [music] even a bucket or pot left with water outside in the frost come to Let's try to cool the canister with water using liquid nitrogen.

[00:02:16]And let's see if it won't burst.

[00:02:25]The first pancake is a lump.

[00:02:28]Since the lower part of the canister is in liquid nitrogen, the water in it turns into ice first. The ice expands and pushes the remaining water out through the open hole.

[00:02:44]Let's continue [music] the experiment with the sealed opening.

[00:02:57]Unfortunately, the self-tapping screw turned him yesterday. I need it does not seal the hole well enough. Water finds some minimal gap and still seeps through under pressure.

[00:03:09]Therefore, first, we will freeze the suspected water leakage point.

[00:03:16]And we will cool the canister as much [music] as possible.

[00:03:30]And while the small carbon dioxide canister is cooling, let's return to the large oxygen one.

[00:03:34]>> [music] >> One of the two oxygen cylinders we have filled with water.

[00:03:43]We will also place it in a container with liquid nitrogen and see if it will burst.

[00:03:52]The cylinder will be cooling there for about an hour. It is only necessary to add liquid nitrogen in a timely manner.

[00:04:01]And now let's return to the small cylinders.

[00:04:07]If you look closely, you can see a thin ice shaving being pushed out through the improperly sealed opening.

[00:04:23]And now, after an hour, the cylinders have warmed up to room temperature and we can check if there are any damages.

[00:04:34]There are no visible damages on the small cylinder.

[00:04:40]This one is slightly swollen.

[00:04:43]And if you look closely, you can see a barely noticeable crack.

[00:04:49]And this canister has already been torn apart quite well.

[00:04:54]Apparently, the least amount of water leaked from it.

[00:04:58]And now let's return to the oxygen cylinder.

[00:05:08]After an hour in liquid nitrogen, no visible damage is noticeable. [music] Now, as quickly as possible, before the canister warms up, we'll try to place it under a 500-ton hydraulic press and see [music] what happens next. While I try to position this canister as evenly as possible under the press, don't [music] forget to subscribe to this channel.

[00:05:31]Believe me, there's a lot of interesting stuff ahead. And to make sure you don't miss anything interesting, be sure to subscribe and hit the bell.

[00:05:41]And this frame should not come back whole. Show them what I'm going to be just that you can notice an uneven gap between the top of the press and the cylinder, indicating that the ice [music] did indeed cause it to swell.

[00:06:46]The frozen cylinder burst under a load of 250 tons.

[00:07:22]On the damaged cylinder, you can clearly see the thickness of the metal.

[00:07:30]It is about 4 mm here.

[00:07:36]We have another cylinder filled with water, but not frozen.

[00:07:40]>> [music] >> Now, we will also place it under the hydraulic press.

[00:08:20]The other cylinder burst under a load of 130 tons. Unfortunately, we do not know what the pressure inside this cylinder was at the moment of rupture.

[00:08:30]But, as I mentioned at the beginning of the video, there is information that these cylinders withstand about 500 atmospheres before bursting.

[00:08:42]Now, we have seen with our own eyes what water under 500 atmospheres of pressure is capable of.

[00:08:51]Even with a thousandfold slowdown of the high-speed camera, it all happens instantly.

[00:09:05]The speed of the water jet in this case was comparable to the speed of a bullet.

[00:09:13]The entire load was taken by a screen made of solid 3 mm polycarbonate.

[00:09:20]And this is not Plexiglas. It is polycarbonate.

[00:09:27]It is much more expensive than Plexiglas and it is intended for making protective screens. Honestly, I am shocked that water broke the polycarbonate. If you recall, in one of the videos, we crushed a railroad rail.

[00:09:45]When it shattered, a huge piece flew at great speed into the side screen made of polycarbonate.

[00:10:01]>> What would damage the railway tools that would know this type wasn't even come close to breaking through. Think about it. This was a steel piece of a rail weighing several kilograms.

[00:10:12]And the water shattered the polycarbonate as if it were ordinary window glass.

[00:10:20]Guys, I think this video definitely deserves a like and of course a subscription to the channel if you haven't subscribed yet.
