    en.wikipedia.org/wiki/Industrial_gas

    Industrial gas. 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. The industry producing these gases is also known as industrial ...

  3. Gas cylinder - Wikipedia

    en.wikipedia.org/wiki/Gas_cylinder

    Gas cylinder. Industrial compressed gas cylinders used for oxy-fuel welding and cutting of steel. A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. High- pressure gas cylinders are also called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over ...

    An oxygen tank is especially dangerous because the gas is stored at a pressure of 21 MPa (3,000 psi; 210 atm)) when full. If the tank falls over and damages the valve, the tank can be jettisoned by the compressed oxygen escaping the cylinder at high speed. Tanks in this state are capable of breaking through a brick wall. [19]

  9. Bottled gas - Wikipedia

    en.wikipedia.org/wiki/Bottled_gas

    Normal high pressure gas cylinders will hold gas at pressures from 200 to 400 bars (3,000 to 6,000 psi). An ideal gas pressurised to 200 bar in a cylinder would contain 200 times as much as the volume of the cylinder at atmospheric pressure, but real gases will contain less than that by a few percent. At higher pressures, the shortfall is greater.
