    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. Gas storage cylinders may also be called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid ...

  3. Acetylene - Wikipedia

    en.wikipedia.org/wiki/Acetylene

    Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". [12][13] It was an accidental discovery while attempting to isolate potassium metal. By heating potassium carbonate with carbon at very high temperatures, he produced a residue of what is now known as potassium carbide, (K 2 C 2), which reacted ...

    A cutting torch being used to cut a steel pipe. Oxy-acetylene Welding (OAW) station. Oxy-fuel welding torch (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline or petrol, diesel, biodiesel, kerosene, etc) and oxygen to ...

  5. Bottled gas - Wikipedia

    en.wikipedia.org/wiki/Bottled_gas

    The acetylene is pumped into the cylinder and it dissolves in the solvent. When the cylinder is opened the acetylene comes back out of solution, much like a carbonated beverage bubbles when opened. This is a workaround to acetylene's propensity to explode when pressurized above 200 kPa or liquified.
