What is the gas source used in the factory?

There are many types of gas sources used in the factory, mainly depending on the production process and needs of the factory. The following are some common factory gas sources:

1. Common industrial gases

Oxygen (O₂)
- Purpose: widely used in oxidation, combustion, oxygen cutting, oxygen welding and other processes. It has important applications in steel, chemical, machinery and other industries.
Nitrogen (N₂)
- Purpose: used for atmosphere control, protection, drying, cooling, inert atmosphere, etc. It has been widely used in metal heat treatment, food preservation, chemical reaction and other fields.
Argon (Ar)
- Purpose: Used to protect arc welding, gas protective welding, metal gas protective welding, etc. In electronics, semiconductors, aerospace and other industries, argon is often used as a protective gas.
Carbon dioxide (CO₂)
- Purpose: used for welding, gas protection, refrigeration, soda manufacturing, etc. It is widely used in beverages, welding, chemicals and other industries.
Hydrogen (H₂)
- Purpose: used for hydrogen welding, hydrogen cutting, hydrogen desulfurization, etc. It has important applications in chemical, electronics, metal processing and other industries.
Acetylene (C₂H₂)
- Purpose: used for flame cutting, flame rod welding, metal gas protective welding, etc. It is widely used in metal processing, shipbuilding and other industries.

2. Other special gases

In addition to the common industrial gases mentioned above, some factories may also use other special gases, such as:

Rarity gases: such as helium (He), neon (Ne), krypton (Kr), xenon (Xe), etc. These gases have important applications in high-tech fields such as electronics, semiconductors, aerospace, etc.
Mixed Gas: A gas made by mixing two or more gases in a certain proportion according to the needs of the production process, such as welding gas mixture (Argon + carbon dioxide), etc.

3. Factors to consider when selecting a gas source

Production process requirements: Choose the appropriate gas source according to the production process and needs of the factory.
Gas Mass and Purity: Some high-precision or high-demand processes require high-purity gases.
Gas supply method and cost: Consider the supply method of gas (such as bottled gas, pipeline gas, etc.) and costs.
Safety Factors: Some gases have flammable, explosive, and toxic properties, and safety issues during storage, transportation and use need to be considered.

4. Conclusion

There are many types of gas sources used in factories. The specific gas selection depends on the production process and needs of the factory. When selecting a gas source, it is necessary to comprehensively consider production process requirements, gas quality and purity, gas supply method and cost, and safety factors.
