Aviation oxygen is also guaranteed for a particular maximum moisture
level -- premise being that it would be 'a bad day' if there were excess moisture and if it froze (impeding oxygen delivery) while at the higher/colder altitudes. Other than that, I'd agree that these three sources are, for most practical purposes, identical aside from the cost. Some more details including regulatory citations: http://www.avweb.com/news/columns/182079-1.html -Dan (Wondering if Santa is going to deliver a plane that will allow me to finally start worrying about needing supplementary oxygen. Probably not, but one can dream. :-) ) |

It's certainly handier than with the tanks laying on the floor. One thing he didn't mention about transportation: Never, move or transport a high pressure cylinder without the screw on cap in place! I don't even move them around the shop without that cap in place. It's really good protection for that high pressure valve. I certainly would want it in place any time I was not using the tank(s) if they were laying down. I don't do that much flying at altitude, but once the tanks got down to 1000 PSI I could use them with the welder and cutting torch. With the Cutting torch or "Rosebud" tip you go through O2 in a hurry. -Dan (Wondering if Santa is going to deliver a plane that will allow me to finally start worrying about needing supplementary oxygen.

Neither of my tanks (neither acetylene nor oxygen) has provision for a cap. Unfortunately. George Patterson The desire for safety stands against every great and noble enterprise. |

Storing tanks upright puts the thickest part of the tank (the bottom) exactly where any moisture will settle. Thus giving the tank a much longer life span against rusting thru. |

Neither of my tanks (neither acetylene nor oxygen) has provision for a cap. Unfortunately. I didn't think they could sell them without them. Tanks have had to have that provision for years. OTOH there are a lot of lost caps floating around... some where. The acetylene and Oxygen tanks on my welding cart both have the caps, but you'd never be able to put them on with the regulators in place. Still, when in the cart they are pretty much protected even if the cart were to tip over. Hasn't yet. If the Acetylene tank were laying down I think I'd have a problem with all the acetone coming out the torch tip.

I thought acetylene had to be stored upright?

Roger wrote: I didn't think they could sell them without them. I don't remember what they call the sizes of my bottles. The acetylene is about 32" high and maybe 7" or 9" diameter. The oxygen is shorter but about as fat. Neither has the threaded collar for a cap. George Patterson The desire for safety stands against every great and noble enterprise. |

Well, my bottle gets transported in a horizontal position when I have to take it on a job, but I've always stored it and used it in a vertical position. I was told there are safety reasons for that, so I've always done that. I was always curious as to what those reasons are, though.

George Patterson Also, and this is a big one, if the valve were knocked off in a vertical position and chained, it would hiss very loudly, and not go anywhere. Horizontal positioned bottles with suddenly removed valves, turn into rockets, and have been known to leave the area at great rates of speed, regardless of what obstacles stand in their ways. I have heard of a tank going through a cement block wall, but I would not doubt that this is an "urban legend". -- Jim in NC |
