Product Description
Product Information
1. Helium can be used as a pressure delivery agent and booster for rocket liquid fuel, and is widely used in missiles, spacecraft and supersonic aircraft.
2. Helium is used as a shielding gas in smelting and welding, which is very important in shipbuilding and the manufacture of aircraft, spacecraft, rockets and weapons.
3. Helium has excellent permeability, [2] used for the cooling of nuclear reactors, and the leak detection of some pipelines and electronic and electrical devices of rockets and nuclear reactors.
4. Helium is a gas with ideal gas properties, and it is an ideal gas for vapor pressure thermometers at very low temperatures.
5. The mass density and weight density of helium are low, and it is non-flammable, which can be used to fill light bulbs and neon tubes, and is also an ideal gas for balloons and airships.
6. Liquid helium can obtain a low temperature close to the absolute temperature (-273 °C), which is used to manufacture superconducting equipment.
7. Helium is a kind of inert gas, the solubility in the blood is lower than that of nitrogen, so its anesthesia is lower than that of nitrogen, so helium is often mixed with oxygen as a breathing gas for divers.

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.
