Angles gas bottles can be stored at?

admin

I know acetylene tanks have to be kept upright when in use and must be allowed to stabilize after transport but what about co2, argon ect can the bottles be kept and used at an angle they fit better on my rigs body that way. Thanks
Reply:Since there is no inversion/ transfer from liquid to gaseous state for helium, argon, co2, I would assume they could be mounted in any position that is practical. I have had my 80/20 gas on its' side once, and there was no issue with it. I welded all day like that.And then, after so much work...... you have it in your hand, and you look over to your side...... and the runner has run off. Leaving you holding the prize, wondering when the runner will return.

Reply:Propane bottles are a case of horses for courses. Lift truck bottle are designed to be used on their sides but most are designed to be upright. Any cylinder with a liquid content (I guess that's what Rojodiabo meant when he said "inversion/ transfer" (doh)) CO2 is the odd one as it sublimes from solid to gas with no liquid phase in normal atmosphere but I'm not sure about in cylinders, where I suspect it may be in an intermediate liquid phase."One of the things we have to be thankful for is that we don't get as much government as we pay for."

Reply:I was hoping to be able to store them at about 22.5 degrees wouldn't use them at that angle. I just wasn't sure if co2 or argon had to stabilize like an acetylene bottle when returned to an upright position. I appreciate all the advice I get from this site. Thanks.
Reply:100% CO2 is a liquid in the bottle ..... should be used standing up, otherwise vaporizing occurs in the regulator/flowmeter.
Reply:Try the co2 atr the 22 degree angle before you scrap the plan.I've used co2 quite a bit flatter than that with no problem. But they do have to be above horizontal, just not by much.Acetelene will work fine and is perfectly safe at an angle of 30 degree from horizontal, osha wrote a variance that allowed that mounting in certain circumastances several years ago.JTMcC.
Reply:If you're drawing gas off the top of a plain cylinder of "gas over liquid", a slight angle from vertical should be fine.  The only exception, I can think of, is if you have a propane cylinder with an OPD valve.  Depending on its orientation, the liquid could raise the float inside.

Reply:ALSO.... when you open the valve on a actyelene tank just to clear any debris, and you smell acetone, take the tank back to the supplier because the acetone will instantly ruin safety check valves in your hoses if you have them.

Reply:For a compressed gas cyclinder, any and all angles are just fine.  Straight up, at an angle, flat on its side, upside down, etc, it won't have any effect because the contents of the cylinder are just gas(es).Don't drop a high-pressure gas cylinder!  Especially on its valve!  Cylinders with liquid in them are another thing.  Acetylene, LPG (liquified propane gas), liquified carbon dioxide, etc, etc, etc usually (almost always, some special cases don't which is why they are special cases) will be used in the vertical upright position.  When the tank with the compressed liquified contents are used vertically, the liquid changes to a gas in the 'head space' (the top part of the cylinder that is not filled with liquid) and then the gas can come out of the valve/regulator.btw, if you draw 'excessive' amounts of gas out of a compressed liquified gas cylinder, you will get the cylinder cold to really-really cold and then the gas flow rate drops off because there is less vapor pressure in the cylinder.  You can experiment and find out what the boiling point of the compressed liquified gas is.  Which for liquid propane is approximately -40 (an interesting number because -40F=-40C).  Actual boiling point of pure propane (what you typically get in a tank of propane is mostly propane but has some other xxx'anes and the odorant) is -42C (-43.6F).  The cooling as the liquid boils/vaporizes in the tank is also why your propane BBQ tank 'sweats' on a humid day when you have the grill cranked up.  The best laid schemes ...

Reply:CO2 bottles are usually half full of liquid. You can eye ball where it would be at the angle you want to haul it. Liquid turning to gas is why CO2 lasts longer than mix gas bottles. If there is one drop of liquid in the bottle you will still have around 650 psi.
