Compressed Gas cylinder - EHS DB.com

There are three major groups of compressed gases stored in cylinders: liquefied non-liquefied and dissolved gases. In each case the pressure of the gas in the cylinder is commonly given in units of kilopascals (kPa) or pounds per square inch gauge (psig). Gauge pressure = Total gas pressure inside cylinder - atmospheric pressure Atmospheric pressure is normally about 101.4 kPa (14.7 psi).
