Product Description

Product Description

    Nitrogen (chemical symbol: N2) is one of the most important components of the Earth's atmosphere, accounting for approximately 78% of the atmosphere. Nitrogen is a colorless, odorless, and odorless gas mainly composed of nitrogen molecules (N2), which have high stability, are not easy to burn, and do not support combustion. It is an inert gas at room temperature and pressure, and does not react with most other substances. Therefore, it is used as an inert gas in many applications, such as protective atmospheres, filling gases, gas refrigerants, etc. In addition, nitrogen has a wide range of applications in food packaging, laboratories, semiconductor manufacturing, and gas liquid separation
    In China, we fill gas use customer old cylinders, because customer use it recycling, so it's old, but we test every year, Our company has the qualification to test steel cylinders. and if we exporting, we must use new gas cylinder.

    Application of Nitrogen (chemical symbol: N2)
1. Inert gas: Nitrogen is a very stable gas that is not easily reactive with other substances under many conditions. Therefore, it is often used as a manufacturer of inert atmospheres to protect materials that are prone to oxidation or corrosion.
2. Gas shielded welding: Nitrogen is commonly used as a protective gas in metal welding to prevent the weld area from reacting with oxygen in the air, thereby reducing oxidation and quality loss.
3. Food preservation: Nitrogen is often used in food packaging, especially for easily oxidizable foods, to extend their shelf life. By replacing oxygen in packaging, the process of food oxidation and spoilage can be slowed down.
4. Pharmaceutical industry: Nitrogen is used in the pharmaceutical industry to protect sensitive drugs and compounds from the influence of oxygen and moisture.
5. Medical use: Nitrogen is used as an anesthetic gas in the medical field, especially in dental surgery. In addition, liquid nitrogen is also used for cryotherapy to remove abnormal cells from the skin.
6. Nitrogen gas pressure filling: Nitrogen is often used to fill gas pressure vessels, such as tires and gas cylinders, to provide stable pressure and performance.
7. Atmosphere control: Nitrogen can be used to control the environmental atmosphere, such as in a laboratory, to maintain specific atmospheric conditions.
8. Liquid nitrogen cooling: Liquid nitrogen is often used in scientific research and industry for ultra-low temperature experiments, for freezing and studying the properties of substances under low temperature conditions.
9. Gas analysis: Nitrogen is also used as a carrier gas in analytical methods such as gas chromatography and mass spectrometry.

B. Our production area
This is the filling area, where liquid gas is transported by tank trucks to the factory and unloaded into low-temperature storage tanks.
During filling, start the low-temperature liquid pump, and the low-temperature liquefied gas is sent to the vaporizer for vaporization by the low-temperature liquid pump. The vaporized gas is transported to the filling workshop and the container filling area for filling operations.
Also sell industrial gases, high-purity gases, food additives (carbon dioxide, nitrogen), standard gases, special gases, laboratory gases, electronic gases, and multi-component laser mixtures;
Provide various deadline irrigation equipment and services for enterprises, and provide customers with safe and professional system solutions through demand analysis, scheme design, installation and debugging, and after-sales service.
C.Inspect
This is a gas laboratory, which includes 3 sets gas chromatography equipment, 1 set continuous gas analyzer, 1 set oxygen analyzer, 1 set dew point analyzer, and 1 set gas analyzer. Our laboratory also has a professional technical team;
In order to better serve society and customers, our company established food nitrogen, food carbon dioxide, and medical oxygen workshops in 2022
