Product Description
Product Information
1. Helium is indispensable as a pressure delivery agent and booster in powering rocket liquid fuels, making it a crucial component in the operation of missiles, spacecraft, and supersonic aircraft.
2. Helium serves as a vital shielding gas in smelting and welding, playing a pivotal role in the construction of ships, aircraft, spacecraft, rockets, and various defense equipment.
3. With its superb permeability, [2] helium is essential for cooling ***s and detecting leaks in pipelines, electronic devices, and electrical equipment used in rockets and ***s.
4. Known for its ideal gas properties, helium is perfectly suited for use in vapor pressure thermometers operating at extremely low temperatures.
5. Helium boasts low mass and weight densities, is non-flammable, and is used to fill light bulbs and neon tubes. It is also the perfect choice for inflating balloons and airships.
6. Liquid helium achieves temperatures near absolute zero (-273°C), making it indispensable in the production of superconducting equipment.
7. As an inert gas with lower blood solubility than nitrogen, helium provides safer anesthesia, often mixed with oxygen for divers' breathing gases.

Q: What's your product price?
A: Pricing for each gas is influenced by market supply and demand, quantity, and purity, making it difficult to set a fixed price. If you are interested in any specific gas, please provide your detailed requirements, and I would be happy to offer you a tailored quote.
Q: What is the minimum order quantity?
A: Minimum order quantities vary across different products. Please share your specific requirements with us, and we will provide the relevant details.
Q: What is the delivery time?
A: If the cylinder is in stock and only requires gas filling, delivery is approximately 7-10 days ex-works after receiving the deposit. Custom cylinder orders require about 15-35 days ex-works post-deposit, depending on the quantity.
Q: How do you ensure gas quality?
A: Our cylinders undergo a thorough treatment process, including cleaning, drying, vacuum pumping, and replacement before gas filling to ensure they are clear and dry. Each treated cylinder is tested for internal purity. After filling, all gases are tested once more. If the gas fails to meet standards, it is reprocessed. Finally, we provide a qualified gas test report.
Q: Are all cylinders recyclable?
A: Typically, seamless steel cylinders are recyclable. However, disposable cylinders are intended for single use only.
Q: Can we send back cylinders to China for refilling?
A: Yes, you can send back our cylinders for refilling. Inform us before exporting, and we will manage all necessary import customs clearance formalities.
