Product Description
Product Information
1. Helium is a quintessential resource in aerospace technology, serving as a powerful pressure delivery agent and booster for liquid fuel rockets. Its indispensability extends to missiles, spacecraft, and supersonic aircraft, ensuring optimal performance and safety.
2. In the realm of smelting and welding, helium emerges as an essential shielding gas. Its critical role in shipbuilding and the manufacturing of aircraft, spacecraft, rockets, and weapons highlights its importance in precision engineering and construction.
3. Renowned for its exceptional permeability, helium is utilized for cooling ***s and is integral in the leak detection of pipelines, as well as electronic and electrical devices in rockets and ***s.
4. Distinguished by its ideal gas properties, helium is the gas of choice for vapor pressure thermometers, particularly at low temperatures, making it invaluable for precise thermal measurements.
5. With low mass and weight density, coupled with non-flammability, helium is the perfect candidate for light bulb and neon tube filling. It also serves as the ideal gas for inflating balloons and airships, emphasizing its versatility and safety.
6. Liquid helium achieves temperatures nearing absolute zero (-273°C), pivotal in the manufacturing of superconducting equipment, where extreme conditions are requisite for groundbreaking technology.
7. As an inert gas, helium boasts lower solubility in blood compared to nitrogen, reducing its anesthesia effect. Frequently blended with oxygen, it is the preferred breathing gas for divers, ensuring safety and comfort underwater.

Our dedication is mirrored in unwavering support and bespoke solutions tailored to our clients in China and worldwide.
Our extensive product range showcases an exceptional variety of gases, including hydrogen (H2), oxygen (O2), nitrogen (N2), argon (Ar), carbon dioxide (CO2), propane, acetylene, helium, laser gas mixtures, silane (SiH4), dichlorosilane (SiH2Cl2), trichlorosilane (SiHCl3), silicon tetrachloride (SiCl4), ammonia (NH3), tetrafluoromethane (CF4), nitrogen trifluoride (NF3), sulfur hexafluoride (SF6), hydrogen chloride (HCl), nitrous oxide (N2O), and doped gas mixtures such as trimethylboron (TMB), phosphine (PH3), and diborane (B2H6). Additionally, we offer noble gases like xenon, neon, krypton, and a spectrum of other electronic gases, emphasizing our commitment to cutting-edge solutions.
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.
