Product Description
Product Information
1. Our premium grade Helium serves as an efficient pressure delivery agent and booster for rocket liquid fuel, making it indispensable in the realms of missiles, spacecraft, and supersonic aircraft.
2. In the fields of smelting and welding, Helium acts as a superior shielding gas, playing a crucial role in the shipbuilding industry and the creation of aircraft, spacecraft, rockets, and advanced weaponry.
3. Boasting excellent permeability, Helium is utilized for the cooling of ***s and is instrumental in the leak detection of pipelines, as well as various electronic and electrical devices associated with rockets and ***s.
4. Renowned for its ideal gas properties, Helium is the preferred choice for vapor pressure thermometers, especially at extremely low temperatures, delivering precise and reliable measurements.
5. With its inherently low mass and weight density, Helium is non-flammable, making it perfect for filling light bulbs and neon tubes, as well as an exceptional choice for balloons and airships.
6. Liquid Helium achieves temperatures nearing absolute zero (-273 °C), a critical component in the production of superconducting equipment, enhancing efficiency and technological advancements.
7. As an inert gas, Helium exhibits a lower solubility in blood compared to nitrogen, reducing anesthesia effects, which is why it's commonly mixed with oxygen as a breathable gas for divers.

Company Information:
Founded in 2016, Jiangsu Deou Gas Co., Ltd. has emerged as a vanguard in the production and export of an extensive range of industrial, specialty, electronic, and medical gases. Our solutions drive innovation across sectors including chemical processing, shipbuilding, electronics, and more. We supply a comprehensive selection of cylinder gases and electronic gases, complemented by integrated solutions such as gas tanks, panels, valves, and fittings. Our commitment is to deliver unparalleled engineering services and develop strategic partnerships worldwide, focusing on innovative, secure, and reliable products, along with steadfast support and tailored solutions.
Our diverse product array encompasses a vast selection of gases including H2, O2, N2, Ar, CO2, propane, acetylene, helium, specialized laser gas mixtures, and electronic gases like SiH4, SiH2Cl2, SiHCl3, SiCl4, NH3, CF4, NF3, SF6, HCl, N2O. Additionally, we offer doped gas mixtures such as TMB, PH3, B2H6, noble gases including xenon, neon, and krypton, alongside 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.
