Isn't it nice that someone's first 2 topics are critisizing experienced builders methods that have problems whatsoever? [:(!]

I'm currently checking out engineering schools, could you please tell me where you're degree is from so I can make sure not to go there?

[syfire]

Okay, everyone say here that im not engineer, but in the state you simply come to unknow individual to engineer with a course, but here in Quebec, we have a lot more of course, im not university, but i dont know the right word that can define me. I got a DEP in Industrial Mechanic, I have worked with a lot of high pressure bottle and i dont know if it's was an exeption, but all the fitting has an anti-backflow valve on it. I don't have studied chemistry, but I have experienced an explosion with cutting torche.

[Drew Rowland]

That's because acetalene does not require an oxidizer to explode. Propane is completely diffrent.

[TurboSuper]

If the torch was propane-based, it was carrying it's own oxygen supply.

[sgort87]

But the oxygen and propane are carried through two different lines to the torch head which prevent those accidents.

Did anyone else laugh for 5 minutes after reading the first post? [:p]

My acetylene torch has no flame arrestor, or anti-blowback valve. I have never even heard of such a thing, and I have several years of metalworking experience. It has a regulator, the regulator has a diaphragm which will work as sort of a check valve. Yes, acetylene is fairly unstable, and it is possible for a tank to explode, but I canot remember ever hearing about an actual incident. The rule of thumb is not to exeed 15psi from the regulator, at higher presures it can become unstable. Inside the tank, the acetylene is dissolved in liquid acetone, which acts to stabilize it.

syfire, just accept it: DR and all those other smart spudgunners out there know a whole lot more than you about fuel v.s. air combustion.

If there was a possible chance of flame going back through the tubes into the tank of propane, then no camp stove or grill would be considered workable or safe by the FCC. Have you ever noticed that on a grill, the fire dosn't go into the little holes? This is because inside the little holes is a 100% (or close to it) propane environment.

"This chain reaction will split the oxygen atoms, causing our entire atmosphere to instantly detonate... and did i really need to recall you that this chamber is NOT herpetic. ( But I am )"

What in the hell is he talking about?
