Product Description

Product Description

  At room temperature, helium is an extremely light, colorless, odorless, and tasteless single atom gas. It is the most difficult substance to liquefy among all gases and cannot solidify at standard atmospheric pressure. When the temperature drops to 2.174K after liquefaction, it has special properties such as low surface tension, strong thermal conductivity, and extremely low viscosity. Low temperatures close to absolute zero can be achieved using liquid helium
    Application of Helium Gas
1. Helium can be used as a propellant and booster for rocket liquid fuel, and is widely used in missiles, spacecraft, and supersonic aircraft
2. Helium is used as a protective gas for smelting and welding, which is very important in shipbuilding, as well as the manufacturing of aircraft, spacecraft, rockets, and weapons.
3. Helium has excellent permeability and is used for cooling nuclear reactors, leak detection of pipelines, electronic and electrical devices in rockets and nuclear reactors.
4. Helium is a gas with ideal gas properties and is an ideal gas for vapor pressure thermometers at extremely low temperatures.
5. Helium has low mass density and weight density, and is not flammable. It can be used to fill light bulbs and neon tubes, and is also an ideal gas for balloons and airships
6. Liquid helium can achieve low temperatures close to absolute (-273 ºC) for the manufacture of superconducting equipment
7. Helium is a type of inert gas with lower solubility in the blood compared to nitrogen, making it less anesthetic. Therefore, helium is often mixed with oxygen as a breathing gas for diver

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
