Product Description
Product Information
1. Helium serves as an essential agent for pressure delivery and rocket fuel boosting, playing a vital role in the aerospace sector. Its application spans missiles, spacecraft, and supersonic aircraft, marking its significance in cutting-edge aviation technologies.
2. As a shielding gas, helium is indispensable in smelting and welding processes. Its role is especially crucial in the construction of ships, aircraft, spacecraft, rockets, and weaponry, where precision and safety are paramount.
3. With its exceptional permeability, helium is employed in the cooling of ***s. It is a key component in leak detection systems for pipelines and electronic devices used in rockets and ***s, underscoring its critical importance in high-stakes engineering.
4. Helium, recognized for its ideal gas properties, is the perfect choice for vapor pressure thermometers at extremely low temperatures, showcasing its versatility in scientific applications.
5. Characterized by low mass and weight density, helium is non-flammable and thus ideal for filling light bulbs, neon tubes, balloons, and airships, extending its utility across various industries from lighting to aviation.
6. Liquid helium reaches extraordinarily low temperatures near absolute zero (-273 °C), making it vital for the manufacture of superconducting equipment, which is pivotal in advancing modern technology.
7. Being an inert gas, helium's lower solubility in blood compared to nitrogen results in reduced anesthetic effects, making it a safer option when mixed with oxygen as a breathing gas for divers, ensuring safety in underwater 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.
