Application
Helium (He) is a colorless, odorless, and non-toxic inert gas with an atomic number of 2. It is located in Group 0 of the periodic table. Here is a concise introduction to its properties, applications, and resources:
1. Physical and Chemical Properties
1. Physical Properties
Density 0.1785 g/L (standard conditions), approximately 1/7 of air, with significant buoyancy;
Boiling point - 268.93ºC, the lowest known boiling point of an element, making it an excellent refrigerant for extremely low temperatures;
High thermal conductivity (5 times that of air), almost insoluble in water.
2. Chemical Properties
Extremely stable in chemical properties, an inert gas, does not react easily with other substances, and has no corrosiveness.
2. Application Areas
1. Aerospace
Used to fill weather balloons and manned airships (safer than hydrogen);
Pressurized for rocket fuel tanks and cooling of aerospace equipment.
2. Medicine
Liquid helium cools MRI superconducting magnets to -269ºC;
Helium-oxygen mixtures alleviate respiratory obstruction such as asthma and COPD.
3. Industry and Research
Welding shielding gas (prevents oxidation, suitable for thick plate welding), semiconductor manufacturing shielding gas;
Leak detection (small molecules, strong diffusion);
Creation of extremely low temperature environments by liquid helium, for research on superconductivity and superfluidity;
Cooling superconducting magnets in particle accelerators.
4. Other Scenarios
Decorative balloons for festivals (safer than hydrogen);
Mixed gas for deep-sea diving (reduces the risks of nitrogen narcosis and decompression sickness);
Helium-neon lasers, food packaging to prevent oxidation (limited application).
*Aerospace & Aircraft:
From manufacturing to flight, helium is widely utilized throughout the aerospace and aircraft industry. In space flight operations, helium is used to purge hydrogen systems and works as a pressurizing agent for ground and flight fluid systems. It is also a source of lift in weather and other surveillance balloons.
*Automotive & Transportation Equipment:
Helium is used to test critical automotive parts such as radiator heat exchangers, air conditioning components, fuel tanks and torque converters to ensure they meet quality specifications. It is also used in combination with argon as a source of inflation in a growing number of airbags.
*Cryogenic Cooling Use:
Helium gas widely used in maglev train and medical Nuclear magnetic resonance (NMR) imaging equipment.
*Ballon Use:
Inflat for ballon for brithday party or celebration or inflat for airship.
*Check Analyse:
Helium gas widely used in vaccum leak detection such as helium mass spectrometer leak detector.

FAQ
FAQ:
1. What's your product price?
Because each gas price is depends on the market supply and demand, quantity and purity, it is difficult to give a fixed price. If you have any interested in each gas, pls give your details requirement. I could like to make an offer to you.
2. What's the min order?
Different products have different min order. Please don't hesitate to let me you're your requirement.
3. What's the delivery time?
If the cylinder is in the stock, and only need to fill gas, the delivery is about 7-10 days ex work after receive the deposit. If the cylinder need to customize, the delivery is about 15-35 days ex work after receive the deposit. That is depends on the quantity.
4. How to check the gas quality?
Firstly, our cylinder will take a treatment (cleaning, drying, vacuum pumping, and replacement before filling gas. In this way, the cylinder inside is clear and dry.
Secondly, we will take tests every treated cylinder to assure them inside purity. Thirdly, we will take a test for all of the gas after fill into cylinders. If the tested gas is not up to standard, we will produce it again and not release the faulty product to ex work. At last, we will supply you the gas test qualified report .
5. All the cylinders can recycle?
Usually seamless steel cylinder can recycle to use in 20 years. The disposable cylinder is only for use one time.
6. Shall we send back the cylinders to China to refill gas again?
Yes, when you ordered our cylinders, next time, you can send back the cylinders to fill gas again. You just need to tell us before you export. We will handle all the importcustoms clearance formalities.
