Industrial Gas Products Properties & Applications

Industrial gases are gases that are manufactured for use in industry. They are typically gaseous at ambient temperature and pressure, and they can be elements, molecular compounds, or mixtures. Industrial gases have a wide range of properties, which make them useful in a variety of applications. The specific properties of an industrial gas determine its suitability for a particular application. For example, oxygen’s high reactivity makes it ideal for welding and cutting, while nitrogen’s inertness makes it ideal for displacing oxygen in food packaging. Industrial gases are a valuable resource for a variety of industries. They can help to improve efficiency, reduce costs, and improve product quality. As the demand for industrial gases continues to grow, so too will the development of new and innovative applications for these gases.

Our Industrial Gas Products








Acetylene is a chemical compound with the formula C2H2. It is a colorless gas with a sweet odor. It is the simplest alkyne, a hydrocarbon with a triple bond between two carbon atoms. Acetylene is highly flammable and explosive, and it is therefore handled with great care.

Acetylene is used in a variety of applications, including:

  • Welding and cutting: Acetylene is the most common fuel gas used for welding and cutting metals. It produces a very hot flame that can be used to melt and join metals.

Acetylene Products:

  • Acetylene
  • Acetylene (S)
  • Acetylene (M)
  • Acetylene pallet (6)


Argon is the third most abundant gas in the Earth’s atmosphere, accounting for about 1% of the total volume.

Argon has a number of important uses, including:

  • Inert atmosphere: Argon is often used as an inert atmosphere in welding and other applications where the presence of oxygen or other gases would be harmful.
  • Light bulbs: Argon is used in incandescent light bulbs to help prevent the filament from oxidizing.
  • Welding: Argon is used in welding to protect the weld area from oxidation.
  • Medical imaging: Argon is used in medical imaging, such as CT scans, to provide contrast.
  • Semiconductor manufacturing: Argon is used in semiconductor manufacturing to create a clean environment for the growth of semiconductor materials.
  • Cryogenics: Argon is used as a coolant in cryogenic applications, such as liquid nitrogen storage.

Argon is a safe and inert gas that has a variety of important uses. It is a non-toxic gas that is not flammable or explosive. 

Argon products:

  • Argon
  • Argon (S)
  • Argon (M)


A colorless and odorless gas with the formula O2. Dioxygen is the primary component of the Earth’s atmosphere, and accounts for about 20.95% of the Earth’s atmosphere. 

Oxygen is also used in many industrial processes, such as the production of steel and iron.

  • Oxygen (S)
  • Oxygen (M)

Carbon Dioxide

Carbon dioxide (CO2) is a chemical compound with the chemical formula CO2. It is found in the gas state at room temperature, and as the source of available carbon in the carbon cycle, atmospheric CO2 is the primary carbon source for life on Earth.

Carbon dioxide is a colorless, odorless, and non-toxic gas. It is about 1.5 times denser than air and is therefore soluble in water. Carbon dioxide is also a greenhouse gas, meaning that it traps heat in the Earth’s atmosphere.

Uses of carbon dioxide

Carbon dioxide has a variety of commercial and industrial uses, including:

  • Carbonated beverages
  • Food additives
  • Fire extinguishers
  • Refrigerants
  • Welding
  • Fertilizers
  • Pharmaceuticals


Nitrogen is the chemical element with the symbol N and atomic number 7. It is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. A colorless and odorless diatomic gas. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth.

Nitrogen uses:

  • Fertilizers
  • Explosives
  • Refrigerants: Nitrogen is used as a refrigerant in some air conditioning and refrigeration systems.
  • Plastics: Nitrogen is used in the production of many plastics, such as nylon and polyurethane.
  • Pharmaceuticals: Nitrogen is used in the production of many pharmaceuticals, such as antibiotics and antidepressants.

Special/Mixed Gases

A combination of two or more gases to form gas mixtures. 

Product available:

  • BlueShield 68

Used for Industrial and professional uses. Mixture consists of 80% Argon and 20% Carbon Dioxide.
