  2. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    The oxygen flow rate is critical; too little will make a slow ragged cut, while too much will waste oxygen and produce a wide concave cut. Oxygen lances and other custom made torches do not have a separate pressure control for the cutting oxygen, so the cutting oxygen pressure must be controlled using the oxygen regulator. The oxygen cutting ...

    en.wikipedia.org/wiki/MAPP_gas

    A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting.. 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.

  4. 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 ...

    Further gas flow in the case of pressure shocks. The entry of air or oxygen into the distribution line or single cylinders. Flashbacks which are the rapid propagation of a flame down the hose. Further gas flow in the event of a burnback. According to the standard DIN EN ISO 5175-1 (formerly EN 730-1) they include a minimum of two safety elements:

  6. Pressure regulator - Wikipedia

    en.wikipedia.org/wiki/Pressure_regulator

    Oxy-fuel welding and cutting processes require gases at specific pressures, and regulators will generally be used to reduce the high pressures of storage cylinders to those usable for cutting and welding. Oxygen and fuel gas regulators usually have two stages: The first stage of the regulator releases the gas at a constant pressure from the ...

  7. Oxygen tank - Wikipedia

    en.wikipedia.org/wiki/Oxygen_tank

    Some shallow divers, particularly naval combat divers, use oxygen rebreathers, and they use a small oxygen cylinder to provide the gas. [ citation needed ] Oxygen is rarely held at pressures higher than 20 megapascals (3,000 psi), due to the risks of fire triggered by high temperatures caused by adiabatic heating when the gas changes pressure ...
