Pressure in a 1lb Oxy cylinder
At my hardware store I've seen red bottles of oxygen and was wondering what the pressure inside them might be. If it is considerably higher than propane I may consider buying for when I want to do serious damage with my semi gun I'm woriking on. Thanks.

Don't. If it's the disposable tanks then they're probably lower pressure than the black steel cylinders.
Using oxygen is a bad idea. Heavier weight, slower speed of sound etc. It will rust any steel parts out and combust with any oils, lubricants etc.
Just don't use it, full stop.

Not to mention that they are left handed threads...
"physics, gravity, and law enforcement are the only things that prevent me from operating at my full potential" - not sure, but i like the quote

Yeah that to. Finding a valve to work and allow you to get all the pressure might be hard. The most common is the welding valve thats made for it and its actually regulated to very low pressures.

Rapid MFR...Damn that was an expensive mistake. I wonder how it happened? Oxygen isn't flammable, so perhaps it corroded the gun and it failed under the extreme pressure?jackssmirkingrevenge wrote:It looked like this until the (lucky to be alive) owner filled it with oxygen instead of compressed air.
Oxygen isn't flammable - but in such a dramatically oxygen enriched environment, the tank itself is.Moonbogg wrote:I wonder how it happened? Oxygen isn't flammable, so perhaps it corroded the gun and it failed under the extreme pressure?
At nearly a thousand times the normal concentration of oxygen, one spark from the hammer valve, and you've got ground zero.
Does that thing kinda look like a big cat to you?

Oh, so this was due to the high pressure of the oxygen I take it. Those guns operate at 200bar.Ragnarok wrote:Oxygen isn't flammable - but in such a dramatically oxygen enriched environment, the tank itself is.Moonbogg wrote:I wonder how it happened?

I took a safety class on handling oxygen. A high oxygen atmosphere lowers the ignition temperature of many items including autoignition and many flammable items become explosive, including oil.Moonbogg wrote:Rapid MFR...Damn that was an expensive mistake.

The oil caught explosively. The use no oil printed on regulators and gauges for oxygen use are for this reason. It is well known that a drop of oil on the high pressure threads of an oxygen regulator will explode when the oxygen cylinder is turned on.

Wait for the oxygen section.

As Tech pointed out above, it was less to do with the high pressure and more to do with the fact that in an oxygen rich environment, any solvents present in the firing mechanism of the airgun would have become highly explosive, it's an accident waiting to happen.Moonbogg wrote:Oh, so this was due to the high pressure of the oxygen I take it.

Maybe i'll use a bit of oil instead of MAPP gas. Looks promising.jackssmirkingrevenge wrote:As Tech pointed out above, it was less to do with the high pressure and more to do with the fact that in an oxygen rich environment, any solvents present in the firing mechanism of the airgun would have become highly explosive, it's an accident waiting to happen.Moonbogg wrote:Oh, so this was due to the high pressure of the oxygen I take it.
