Compressed oxygen in a Nitro tank????

[Retarded_Turtle]

Ahhhhh! my dad has a compressed oxygen tank for welding i think, and i was hoping i could use that and get a fill station. I would use my Nitro tank and im wondering if the shrapnel from the explosion will tear my head off, or will it work just like compressed air?????????????

[MINDofSIN]

This should be in the air forum.

Compressed Air=Oxygen I think


Does your dads compressed oxygen tank fill to something like 3000psi?

[Retarded_Turtle]

ya i think

[EvilDead]

I would be worried about the scrapnell! there is oxygen in compressed air, but not 100% oxygen, pure O2 is extremly flamable:eek: not to mention deadly if inhaled. Thats why nitrogen is used its not flammable!:D

[Deep Sixx]

GOOD GOD NO!! Do not use that in your HPA tank... EVER. Use only compressed air in those tanks. Compressed air (HPA) is NOT oxygen!! The air you breathe is NOT oxygen... it's actually mostly nitrogen. The air in our tanks is just that... air. Not exclusively oxygen or nitrogen... air. Pure oxygen is extremely flammable and very dangerous.

Only have your tanks filled by trained and certified people using the proper equipment.

BTW, if your tank ruptures it will take your head off even if it's filled with compressed air.

Don't try that Liquid O2 is what they use in rocket fuel therefore very flamable.

actually the oxygen isn't what is flammable it is just raw fuel for fire pure oxygen alone won't catch fire

I don't know where you're getting your information from, but it's wrong. Pure oxygen is highly reactive, meaning it will burn or explode or whatever very easily. Only the noble gasses are non-reactive, and oxygen isn't one of them. The noble gasses are helium, neon, argon, krypton, xenon, and radon.

[kingalls]

I completely agree. Compressed air is useable because it is ~75% nitrogen, which is non-reactive. Oxygen, however, is highly reactive and highly flammable. Look on the internet for a video of a man lighting a grill with liquid oxygen. You'll understand what I mean. Just pay a couple of bucks a fill and avoid the problems

Sorry dude... you need to go back to physics class. Liquid oxygen is extremely flammable. Remember the Space Shuttle Challenger explosion... or the Apollo-1 fire? That's liquid oxygen.

Yeah, Apollo 1 is a pretty good example of what oxygen can do...like burn, and burn very well.

I think that the Challenger explosion was more due to the solid booster rocket exploding, as the o-rings where the booster segments joined had frozen from the extreme cold

Yeah, the SRB o-ring ruptured, which caused flames to exit the side of the SRB, igniting the liquid oxygen and hydrogen in the fuel tank.

Pure oxygen CAN NOT BURN. If you attemt to burn pure O2 from a chemical point of view, you only get warm O2. In order to combust it needs something for fuel. Add CH2 (ethane), and suddenly you have an explosion: 3 O2 + 2 CH2 -> 2 CO2 + 2 H2O. You don't need a hydrocarbon for it to burn though, wood, charcoal, paper, etc will all burn quite well. Apollo-1 was an electrical fire, but in a pure oxygen enviroment. Things burn faster and hotter as you add more O2. That's why when you add liquid O2 to a BBQ fire, the charcoal combusts at 15,000* F. Leper was correct about the Challenger explosion.

Pure oxygen IS very reactive when heated, but in a very different way. It is one of the most corrosive things known. Expose anything metal to it and it oxidizes (aka rusts). You would drastically reduce the life of your gun. A cutting torch works on this principle. It heats the metal to a very high temp, then spays pure O2 at it, rusting it through and effectively cutting it.

In short do not use it.

PS, I think chemisty is a better class than physics for this topic. ;)

He's right, 02 doesn't burn by itself, it make other things burn. With pure o2 it makes other stuff real flammable.




Plus, whenever somebody is putting chemical equations in their posts you gotta agree with them.:laugh:

3 O2 + 2 CH2 -> 2 CO2 + 2 H2O + Lots of energy

JESUS CHRIST DO NOT FILL YOUR TANK WITH O2!!!

The oil you used for your maintainence + O2 + high pressure = Massive Fireball + No Hands and/or arms!!

The O2 when it touches the oil and under the high pressure used by markers causes the O2 to combust, the fireball procedes to blow your hands and reg off, and then the rest of the O2 vents into the Fireball and turns the tank and what is left of a marker into a rocket and ripping apart anything it touches. This is why deep sea scuba gear uses self- lubricating o-rings AND MUST NEVER EVER BE OILED OR LUBRICATED WITH ANYTHING!!!

Ethane is CH4

[FinnMcKool]

they don't use o² in deep sea scuba they use three different gasses mixed, one of them might be o² but it wouldn't be half as dangerous.

[Lord Delta]

They also use helium sometimes. Saw this show where they were trying to live underwater in some study. Had to use helium to keep from getting the bends. There were like 3 guys living down there and they all talked funny because of the helium. In the movie the sphere, they briefly talk about that. Sorry I've gone way off topic.

[OneArmedScissor]

you don't get the bends from being under water... you get it when you come to the surface too fast under water. creating air bubbles in blood.

they use nitrogen, oxygen, and something else in scuba tanks.

[ds613]

The bends is caused by n2 accumulation in the blood.

I'm guessing that since they can't use pure oxygen, they use air when their not going very deep (air is mostly n2), and o2 + helium when they go really deep (unless they have a pressurized suit or submersible). I'm just guessing though.

DO NOT USE O2 THAT SIMPLE VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY VERY DANGEROUSE

[blinkpk11]

ok guys i think he gets it now. if he doesnt well, he needs to fill his tank with o2 so he wont reproduce :) :D
