Product Description
Product Information
1. Helium, a versatile marvel, serves as a pressure delivery agent and booster for rocket liquid fuel, playing an essential role in the propulsion systems of missiles, spacecraft, and supersonic aircraft, where precision and reliability are paramount.
2. Helium's unique properties as a shielding gas make it indispensable in the fields of smelting and welding, especially in industries such as shipbuilding, aerospace, and defense, ensuring the durability and integrity of aircraft, spacecraft, rockets, and weaponry.
3. With its remarkable permeability, helium is employed in cooling ***s and plays a crucial role in leak detection for pipelines, as well as in electronic and electrical devices within rockets and reactors, safeguarding against malfunctions and ensuring operational excellence.
4. Helium, boasting ideal gas properties, is the perfect choice for vapor pressure thermometers designed to function at ultra-low temperatures, offering exceptional accuracy and stability in extreme conditions.
5. The low mass and weight density of helium, combined with its non-flammable nature, make it ideal for diverse applications such as filling light bulbs and neon tubes, as well as being the gas of choice for balloons and airships, ensuring safety and efficiency.
6. Liquid helium achieves temperatures close to absolute zero (-273 °C), making it indispensable in the fabrication of superconducting equipment, where its cooling capabilities are unmatched.
7. As an inert gas with low solubility in blood compared to nitrogen, helium's reduced anesthetic effect makes it an ideal component in breathing mixes for divers, when combined with oxygen, promoting safety and reducing risks during deep-sea explorations.

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.
