Gas bottle mounting angles

OR, could they be mounted at a 45, particularly an acetylene? I don't believe CO2 is in liquid form as usually delivered. cheers T.Alan When I used to work in a local gage test shop (pressure, temperature, etc.) we made our own dry ice blocks for temperature tests. This was done by inverting the CO2 bottle and running the output through a two piece block with a filter screen on the exhaust side. When in the normally upright position the tank output is gas only. When inverted the output is _defiantly_ a liquid. (and bloody cold at that grin) Regards, Bob rgentry at oz dot net |

I've never heard a good explanation why though, other than that the gas supplier would rather rent you yet another cylinder, this one with a dip tube running down inside. |
