When using acetylene, experience indicates that 15 psig is
generally acceptable as a safe upper pressure limit. Using acetylene at pressures in
excess of 15 psig pressure (or about 30 psia
pressure) is a hazardous practice. Free gaseous acetylene is potentially unstable at pressures above 15 psig and could decompose with explosive violence. The decomposition characteristics of acetylene gas are avoided by keeping the gas in liquid solution and storing it in cylinders of unique construction. |
