Gas cylinders following a large blaze in Tamanrasset, Algeria.
E
3 legendary gas cylinders and 1 common one
S
+150 fire damage.
K
Anointed Legendary
L
Urad anoint?
G
Spice Infused
B
These are only epic
D
But one is enchanted
E
Right, been a while since my last mmorpg, played Wildstar until it was shutdown and haven’t touched another since
I
Clearly epic. And oddly. Lowest rarity? Uncommon. Not common. Go figure.
D
Well common is white items but they don’t get a special designation. And trash is gray.
1
Wrong, these are only epic.
B
Yes obviously you pick up those ones!
B
Nah epic
H
Its just epic gas cylinders. The legendary are golden.
Z
Can’t tell from the pictures but, if the tanks have an empty valve port they aren’t dangerous. I assume they don’t since that mount of heat could probably pop a sealed cylinder even if they had no fuel inside?
S
Yes, without that valve, in many parts of the world, and internal temperatures of 110-150°C *and* internal pressure up to 13 MNmm2 (1 900 psig), the cylinders can burst violently.
Z
Since you came with specs, do you know if the fittings are designed to fail before the tank reaches critical? I imagine it varies by regional regs but still
S
Yes, a valve is expected to open if the temperature and pressure increase, releasing the gas. I think that must have happened with the tanks in the photo, if they had gas in them, or they would have exploded at that red-hot temperature.
Z
I kinda figured, thanks!
B
Burst or rupture disc in oxygen cylinders, and fusible plugs (melts at 212F) in acetylene cylinders and possibly other fuel gases (not 100% on that)
B
Spicy bottles, i wouldnt be standing that close.
U
No chance there’s still gas in them
M
Like is everyone in this thread just ignorant that the bottles have a prv built in and they would have burnt off all the gas that was inside them long ago and they are now just red hot steel?
A
I think so do you think that’s super common knowledge?
C
That’s Hank Hill you’re talking to, show him some respect
O
Dammit Bobby
L
I’m okay dad…
M
Remember taste the meat, not the heat.
S
my first thought was “i wouldnt be standing that close,” followed *immediately* by “actually theres no way theres any gas left in those, its just a hunk of steel now” not so much the pressure release valve, just the fact that the fuel inside would have ignited like 1500 degrees ago.
B
Not without oxygen it wouldn’t.
T
The tanks are red hot. Look at the top and notice the white hot pressure relief valve. It’s seen heat.
R
Gotta watch more industrial accident videos by the NCSB
I
Get ’em before they’re gone.
B
I mean even still, assuming we didn’t see the gas escape, should we trust it?
D
If you understand physics, yes you should trust it. That said, while irrational I absolutely understand the immediate reaction of “get away from that”. And in such a situation unless your an emergency responder you really should be getting away.
M
Why would it not be common knowledge? Safety valves are on pretty much every pressure vessel you can buy
W
Because buying pressure vessels is not something everyone does. I know I don’t.
M
Do you have a propane grill? Do you have an air compressor with a tank? Do you have a hot water heater that’s not the tankless style? All of those are pressure vessels And have safety pressure relief valves.
W
I have none of those things.
S
think of all the children that got left behind, though.
M
Every video you see of a gas bottle fire shows the prv let go and only if the fire is hot enough to overcome the release speed do the bottles fail and go big kabloey, do people go through life never learning the basics of what’s around them? Now that I type it out yeah I can see that but to have 10 ppl post a content about how the bottles are spicy and it have 50 up votes before anyone says anything about how that’s not the case
P
I’d say like a tiny % of people on Reddit know anything about pressure vessels or the meaning of PRV, BLEVE, etc.
T
FYI, most cylinders don’t have RPVs. Source: I work in specialty gases.
M
Wow you’re so knowledgeable and smart!!!! Most people like me have no idea how gas bottle will interact with a fire!!! We all just know kaboom!!!!!
P
Not everyone is Hank Hill like you are
B
I do know about the pressure release valves they have but i have also seen enough videos of vehicles transporting them and crashing and then you see them go off and fly in every direction even tho they all should have these release valves aswell. I’ve also played enough with explosives and made my own to know this shit can be dangerous and sometimes unpredictable so i’d rather get laughed at for being a bit too cautious than loosing my hand or other important bits and end on the darwin award subreddit.
N
If it looks like a bomb, it’s best to let someone else do the finding out
R
Clearly, you didn’t play with enough explosives to lose a digit or two…amateur /s
H
The release valves are often what’s making them decide if they want to go into orbit. It’ll stop it from exploding, but it that process, creates a little rocket engine.
B
Sure. But I’ve also seen BLEVE explosions and those tanks also have pressure release valves, so I’d be standing back
