Product Description
Product Information
1. Helium is an exceptional pressure delivery agent and booster for rocket liquid fuel, making it indispensable in the fields of missiles, spacecraft, and supersonic aircraft.
2. As a shielding gas, helium plays a crucial role in smelting and welding, particularly vital in the construction of ships and the production of aircraft, spacecraft, rockets, and military weapons.
3. Renowned for its excellent permeability, helium is pivotal for cooling ***s and detecting leaks in pipelines, as well as electronic and electrical devices used in rockets and ***s.
4. With ideal gas properties, helium is the perfect choice for vapor pressure thermometers operating at extremely low temperatures.
5. Helium's low mass and weight density, coupled with its non-flammable nature, make it ideal for filling light bulbs and neon tubes, and it is the gas of choice for balloons and airships.
6. Liquid helium achieves temperatures near absolute zero (-273 °C), essential in the development of superconducting equipment.
7. As an inert gas with lower solubility in blood than nitrogen, helium's anesthesia effects are reduced compared to nitrogen, making it a preferred component, blended with oxygen, for divers' breathing gas.

Company Information:
Founded in 2016, Jiangsu Deo Gas Co., Ltd. is a trailblazer in manufacturing and exporting a comprehensive spectrum of industrial, specialty, electronic, and medical gases. Our gases are indispensable across numerous industries, including chemical processing, shipbuilding, electronics, optical fiber communication, machinery manufacturing, food and beverage, medical, solar photovoltaic, LED, aerospace, and scientific research. Our offerings include a wide range of cylinder and electronic gases, complemented by integrated solutions such as gas tanks, panels, valves, and fittings. We pride ourselves on providing outstanding engineering services to our valued customers in China and around the world, with a steadfast mission to forge global partnerships that deliver innovative, reliable, and secure products, supported by dedicated service and customized solutions.
Our broad array of products features an extensive selection of gases, including H2, O2, N2, Ar, CO2, propane, acetylene, helium, laser gas mixtures, SiH4, SiH2Cl2, SiHCl3, SiCl4, NH3, CF4, NF3, SF6, HCl, N2O, and doped gas mixtures like TMB, PH3, and B2H6. We also provide noble gases such as xenon, neon, and krypton, along with a variety of other electronic 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.
