Cryogenic equipment are devices that used in generating, sustaining or operating at a very low temperature. We know that even refrigerators work at low temperatures but the remarkable difference in working of cryogenic equipment and refrigerator is -180 degree centigrade. General equipment that is used in the formation of a complete cryogenic application include a container, cold traps, pressure vessel, purifiers and pipes. Some of the common yet very vital application of cryogenic equipment includes the safe transportation of cooled liquids like liquid nitrogen, liquid oxygen, liquid helium, liquid, liquid argon and many other supercooled gasses. For example, transfer lines offer a very safe means of transferring liquid cryogens from one place to another without any risk to the workers as well as to the machinery.
