Oxygen (O2) is a colourless and odourless gas, but it is pale blue in the liquid form. It is vital for most life forms on earth. We absorb oxygen through the air we breathe. Oxygen is produced in our factory through the liquefaction and distillation of ambient air at air separation plants.

The main industrial application of oxygen is combustion. Many materials that do not normally burn in air will burn in oxygen so mixing oxygen with air greatly enhances combustion efficiency in iron and steel, non-ferrous, glass and concrete industries. It is widely combined with a fuel gas for cutting, welding, brazing and glass blowing, offering much higher flame temperatures and thus greater efficiency than just air. With oxyfuel, plasma and laser processes, a jet of gaseous oxygen is used to cut steel. Besides, Oxygen is widely used in many industries such as petrochemicals and chemicals, health and wellness, food industry …

We provide oxygen in both liquid and gaseous form. The oxygen gas is delivered by 40L, 50L cylinders and pallets or refilled in the refilling station in the factory. The liquid oxygen is distributed by LGC, ISO tank or pumped directly at the factory.

What is Oxygen?

Industrial oxygen gas has many applications in daily life as well as in production. Industrial oxygen is widely used in many industries such as: welding and cutting metal, in medicine, in the environment..etc.

Oxygen (from the French oxygène /ɔksiʒɛn/, also written as oxygen, oxygen, or oxygen). A chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table. A highly reactive nonmetal and an oxidizing agent readily oxidizing with most elements as well as with other compounds. After hydrogen and helium, oxygen is the third most abundant element in the universe by mass.

The properties of oxygen gas

  • Oxygen element symbol: O
  • Formula of single substance (molecular): O2
  • Oxygen’s Atomic Mass: 16
  • Molecular Mass of Oxygen: 32
  • Oxygen is a colorless, odorless substance, sparingly soluble in water.
  • Oxygen has a molecular mass of 32 so oxygen is heavier than air.
  • Oxygen when liquefied at -1830C will have a light blue color and can be attracted by magnets.

Applications of industrial oxygen in industries

  • Industrial oxygen gas is used to cut and weld molten metal. Gas mixtures are capable of generating temperatures up to 3000ºC and 2800ºC. Examples include an oxy-hydrogen gas mixture and an oxy-acetylene blowtorch.
  • A high temperature flame is applied to melt by heating between the junctions. The ends are melted and solidified. Also for cutting metal one end is heated until it turns red. The Oxygen level will be increased until the red-hot component is oxidized. It is this that softens the metal so that it can be cut.
  • Applications of Industrial Oxygen in the Medical Industry: Oxygen is a gas that helps patients breathe and breathe in times of danger. In addition, oxygen is also used at home and is often referred to as home breathing oxygen.
  • Applications of Industrial Oxygen in Diving: Divers use Oxygen to create an atmosphere so they can stay underwater longer.
  • Application of Industrial Oxygen in the sanitation industry: Oxygen is effectively applied to water treatment as well as to clean the environment and air.
