Oxygen

Colorless & odorless gas, not very active at room temperature, is widely used in smelting, chemical industry, national defense, medical treatment, especially in machinery enterprises.

Argon

A rare gas. Used as shielded gases for arc welding (cutting) of stainless steel, magnesium, aluminum, and other alloys. It is also used in the smelting of steel, aluminum, titanium, and zirconium. Argon emits a purple glow during discharge and is also used for lighting technology and filling fluorescent lamps, photovoltaic cells, lighting tubes, etc.

Hydrogen

Hydrogen is a highly inflammable, colorless, transparent, odorless, and tasteless gas. Therefore, hydrogen can be used as the filling gas for airships and hydrogen balloons, mainly used as reducing agents.

Helium

Helium is colorless, tasteless, and non-combustible. The content of the air is about 5.2 parts per million. The chemical properties are not active and are widely used in the fields of industry, medical treatment, fire protection, and scientific research.

Carbon Dioxide

It is a colorless and odorless gas at room temperature. Its density is slightly higher than that of air. Its molecular structure is very stable. Its chemical properties are not active and it will not react with the fabric. It is used as a fire extinguishing agent, gas fertilizer, medicine, and so on.

LPG

Liquefied petroleum gas generally refers to liquid petroleum gas.

Because of its high calorific value, smokeless, carbon-free slag, easy operation, and use, it has been widely used in people's lives. In addition, liquefied petroleum gas (LPG) is also used for cutting metals, baking agricultural products, and industrial kilns.

Nitrogen

Usually, it is a colorless and odorless gas, and generally, nitrogen is less dense than air.

Nitrogen is chemically inert and difficult to react with other substances at room temperature, so it is often used to make preservatives.
