    Further, more of it can be stored in a single place at one time, as the increased compressibility allows for more gas to be put into a tank. MAPP gas can be used at much higher pressures than acetylene, sometimes up to 40 or 50 psi in high-volume oxy-fuel cutting torches which can cut up to 12-inch-thick (300 mm) steel.

    A gas cylinder is used to store gas or liquefied gas at pressures above normal atmospheric pressure. [2] In South Africa, a gas storage cylinder implies a refillable transportable container with a water capacity volume of up to 150 litres. Refillable transportable cylindrical containers from 150 to 3,000 litres water capacity are referred to as ...

    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. History of manufactured fuel gases - Wikipedia

    The gas industry did not cede the gas lighting market to electricity immediately, as the invention of the Welsbach mantle, a refractory mesh bag heated to incandescence by a mostly non-luminous flame within, dramatically increased the efficiency of gas lighting. Acetylene was also used from about 1898 for gas cooking and gas lighting (see ...

    en.wikipedia.org/wiki/MAPP_gas

    MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane.
