30 minutes minimum, but I typically give them at least an hour when moved locally. Long distance, half a day or more.What was the time recommendation for standing acetylene bottle upright before using them? I used to know it, but forgot.
Son, That bike looks like it would be hardly able to haul that.I'm new here
That could be, but there is an important reason not to lay acetylene bottles flat. You will end up with acetone liquid in your gauges. That will ruin them for sure. What I was told was IF you lay them, then they must be stood up and allowed to settle with the acetone/acetylene mixture to be absorbed once again with the medium at the bottom 2/3rds or so. A quick clip from the net:Concealed is my preferred transport manner. (Secure also, of course.) I don't feel the need to invite trouble from authorities.
Maybe this is old tech, but I was taught at a welding course years ago that fuel cylinders (propane, acetylene, etc) shouldn't be laid horizontal (unless approved for it) because the valves aren't intended for liquid-fuel contact.

I'm pretty sure bottles of compressed gas, fuel or oxidizers need the caps for any transport (including in the building on the welding/welder cart, not that anybody goes that far) as well as needing to be vertical. They should not be in a closed space that isn't vented. So no car trunks, technically no vans or SUV's, that leaves only open P/U (w/cap with open windows), flat beds, curtain side trucks or roll tarped trucks. I won't pay for trucking and I have typically had vans, SUV's and now a mini P/U with hard tonneau, so I move mine illegally. [SHHHH!] I strap anything even remotely heavy sometimes excessively. Pick ups with a cap may be fine as it isn't connected to the drivers cabin and the tailgates aren't air tight, that will/may be at the interpretation of the road side proctoligist [LEO of authority] Harry
I can't imagine anyone would ever say anything about how you transport them unless you have a business vehicle. Not everyone owns a truck.I'm pretty sure bottles of compressed gas, fuel or oxidizers need the caps for any transport (including in the building on the welding/welder cart, not that anybody goes that far) as well as needing to be vertical.

In my region anyway.... I can say that any transportation authority thats paying attention will have something to say about it. Just like visibly carrying more than 6 jerry cans in pickup; or easily seeing jerry cans thru a window of a car/suv/van.I can't imagine anyone would ever say anything about how you transport them unless you have a business vehicle.

Agreed. They'll never see mine in the back of the SUV anyway, nor would they be able to see my gas cans through the rear window.In my region anyway....

Thats why I'll always keep a gas cylinder out of sight.
That feels more daring than just laying them down.I just transported my 300cuft argon cylinder and picked up and filled a new 100lb (23gal) propane cylinder yesterday. Tractor Supply had the 100lb tank on sale for $129 down from $229.
Used the utility trailer, I transport them vertically. Wrapped a moving blanket around them, then strapped to a dolly and the dolly and tank strapped to the vertical back ramp of the utility trailer.
Propane is required to be transported vertically.That feels more daring than just laying them down.
I stand corrected, my propane does stay vertical behind the back seat. The rest of mine get laid down.Propane is required to be transported vertically.
I've done the argon vertical and horizontal, vertical is easier to strap and secure.
DOT frowns on trasnporting compressed gas cylinders laying down. Just sayin'...I have enough bottles that I wait for at least two bottles, I have them Laying down with the valves facing towards the cab and strapped together so they can't roll. I also strap them so they can't move side to side.
I also drive like I have about a ton of TNT in the bed of my truck, I have seen pictures of hauling bottles gone bad.
Be safe!
OSHA allows transportation laying hoizontally, secured to a cart for "short durations". That is for non vehicluar transportation.DOT frowns on trasnporting compressed gas cylinders laying down. Just sayin'...
