Product Description

 

 

Description:

Helium (He) is an inert, non-toxic, colorless, and odorless noble gas with applications in industrial, medical, aerospace, and scientific fields. As a noble gas, helium is chemically inert and does not react with most substances, making it ideal for high-purity and specialized applications. It is commonly used in cryogenics, welding, leak detection, and as a lifting gas for balloons and airships.

 

Product Features:

• Chemical Formula: He
• Molecular Weight: 4.0026 g/mol
• Physical Properties: Colorless, odorless, and non-toxic gas with a density of approximately 0.1786 g/L at room temperature and atmospheric pressure
• Melting Point: Not applicable (Helium remains a gas at standard atmospheric pressure)
• Boiling Point: -268.93 °C (-452.07 °F)
• Reactivity: Chemically inert; does not react with most elements or compounds, making it stable and safe for various applications.

 

Applications:

• Used in cryogenic applications, including cooling superconducting magnets in MRI machines and scientific research.
• Essential for welding applications, providing an inert shielding atmosphere for high-temperature metalwork.
• Applied in aerospace and space exploration, including purging fuel tanks and pressurizing rocket systems.
• Utilized in leak detection for high-precision industries such as electronics and semiconductors.
• Used as a lifting gas in balloons and airships due to its low density and non-flammable nature.
• Employed in specialized gas mixtures for research and industrial applications requiring a high-purity inert atmosphere.

FAQ

• What's your product price?
  The price of each gas depends on market supply and demand, quantity, and purity, so it is difficult to provide a fixed price. If you are interested in any gas, please provide your detailed requirements. We can then negotiate the most reasonable price.

• What's the minimum order quantity?
  The minimum order quantity varies for different products. Please feel free to let us know your requirements.

• What's the delivery time?
  If the cylinder needs customization, the delivery time is approximately 35 days after receiving the deposit. The exact time depends on the quantity.

• How do you check the gas quality?
  Firstly, our cylinders undergo a treatment process, including cleaning, drying, vacuum pumping, and replacement, before filling the gas. This ensures that the inside of the cylinder is clean and dry. Secondly, we test each treated cylinder to ensure its internal purity. Thirdly, we test all the gas after it has been filled into the cylinders. If the gas does not meet the standard, we will produce it again and will not release any faulty product. Finally, we will provide you with a gas testing qualification report.
