The storage cylinders may be used independently in sequence using a portable transfer whip with a pressure gauge and manual bleed valve, to transfill the receiving cylinder until the appropriate fill pressure has been reached, or the storage cylinders may be connected to a manifold system and a filling control panel with one or more filling whips.
Internally, the blending equipment and diving cylinders must be oxygen clean; all fuels and particles which could be sources of ignition must be removed. [ 6 ] [ 7 ] [ 8 ] The materials chosen for use in the valves, joints and compressors must be oxygen compatible: they must not burn or degrade readily in high oxygen environments.
The pressure vessel is a seamless cylinder normally made of cold-extruded aluminum or forged steel. [5] Filament wound composite cylinders are used in fire fighting breathing apparatus and oxygen first aid equipment because of their low weight, but are rarely used for diving, due to their high positive buoyancy.
Whips are commonly named for their intended use, e.g. filling whip, for filling cylinders, decanting, transfill or transfer whip for decanting between cylinders, oxygen whip for oxygen transfer, blending whip, for decanting gases when blending gas, etc. Accessories may include a flow control valve, bleed valve, pressure gauge, and/or whip check.
Medical oxygen storage tanks at the Royal Women's Hospital, Melbourne, Australia. Oxygen may be used for patients requiring supplemental oxygen via mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around 345–380 kPa (50.0–55.1 psi), [1] [2] or in the UK and Europe, 4–5 bar ...
