Now a lot of customers are saying, 'Wow, helium is expensive! More expensive than the balloon I bought, is it a mistake? The United States currently produces most of the world's helium, and the mine is likely to be mined for up to another 30 years. In other words, helium is now a scarce resource. Currently, the global price of helium gas is largely controlled by one American plant. Helium is sure to get more expensive, both in China and Chengdu. It is distinguished by its chemical composition. But both gases can make balloons float, but the prices vary widely, with a 40-liter tank of helium costing about 1,600 yuan and a tank of hydrogen about 80 yuan. Helium is a safe, inert gas; Hydrogen, on the other hand, is a more active gas, which can easily cause deflagration when it hits Mars. In order to reduce the cost, street vendors use cheap hydrogen filling. Please stay away from street vendors for your own safety.

Helium gas applications —— Part1

High purity helium gas is widely used in military industry, scientific research, petrochemical, refrigeration, medical treatment, semiconductor, pipeline leak detection, superconducting experiment, metal manufacturing, high-precision welding, optoelectronic product production, etc.

1. High-purity helium gas is used as protective gas: helium gas is often used for welding protective gas of magnesium, zirconium, aluminum, titanium and other metals by virtue of its inactive chemical properties.
