  2. Gas cylinder - Wikipedia

    en.wikipedia.org/wiki/Gas_cylinder

    A gas cylinder quad, also known as a gas cylinder bundle, is a group of high pressure cylinders mounted on a transport and storage frame. There are commonly 16 cylinders, each of about 50 litres capacity mounted upright in four rows of four, on a square base with a square plan frame with lifting points on top and may have fork-lift slots in the ...

  3. Bottled gas - Wikipedia

    en.wikipedia.org/wiki/Bottled_gas

    The general rule is that one unit volume of liquid will expand to approximately 800 unit volumes of gas at standard temperature and pressure with some variation due to intermolecular force and molecule size compared to an ideal gas. Normal high pressure gas cylinders will hold gas at pressures from 200 to 400 bars (3,000 to 6,000 psi). An ideal ...

    en.wikipedia.org/wiki/Cascade_filling_system

    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.

  5. Industrial gas - Wikipedia

    en.wikipedia.org/wiki/Industrial_gas

    A gas regulator attached to a nitrogen cylinder. Industrial gases are the gaseous materials that are manufactured for use in industry. The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders.

  6. Specific volume - Wikipedia

    en.wikipedia.org/wiki/Specific_volume

    The standard unit is the meter cubed per kilogram (m 3 /kg or m 3 ·kg −1). Sometimes specific volume is expressed in terms of the number of cubic centimeters occupied by one gram of a substance. In this case, the unit is the centimeter cubed per gram (cm 3 /g or cm 3 ·g −1). To convert m 3 /kg to cm 3 /g, multiply by 1000; conversely ...

  7. Liquid nitrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen

    Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg -1 ⋅K -1 and heat of vaporization of 200 kJ⋅kg -1 makes it extremely useful in a wide range of applications ...
