Product introduction
Under normal temperature and pressure, hydrogen is a gas that is extremely flammable, colorless, transparent, odorless, tasteless and difficult to dissolve in water. Hydrogen is the world's smallest known density gas. The density of hydrogen is only 1/14 of that of air. At 0 °C, the density of hydrogen is 0.089 g/L at a standard atmospheric pressure. Therefore, hydrogen can be used as a filling gas for airships and hydrogen balloons (due to the flammability of hydrogen, the safety is not high, and the airship is now filled with helium gas). Hydrogen is the smallest molecular weight substance and is mainly used as a reducing agent.

Stored in shady, cool, dry, eventilated warehouse, and keep away from sunlight and any ramming.
Q4:What is the payment terms?
A:30% T/T in advance, balance against the B/L.
Q5:How to check gas quality?
A: Before filling the gas, the cylinder will be treated carefully, such as cleaning, drying, vacuum pumping and replscement.
Then, we will take tests every treated cylinder to assure them inside purity.
Thirdly, we will take a test for all the gas after fill into the cylinder, to make sure the quality of the gas along with the tested reported.
Q6: If the cylinder recycled and can be refilled gas again?
A: Yes, usually the seamless steel cylinder can recycle to use for 20 years, and also can be refill gas again.
But , when you ordered our cylinder, you have to inform us before exporting, we will handle all the import customs clearance formalities.
Q7:Why choose us?
A: Fast delivery, Factory price and soonest reply within 24 hours.
