Helium Gas
Helium GasHelium (He) is a noble gas widely used in semiconductors, laboratories, medicine, aerospace and commercial balloon decoration. Bonyan Gas Pishro supplies helium in various grades for professional and industrial use, to meet the needs of factories, laboratories, hospitals, gas-mixing companies and helium balloon shops.

Helium gas grades
The purity of the helium you choose directly affects your project’s results and financial return. For example, in ultra-sensitive technologies such as semiconductor manufacturing or gas chromatography analysis, the slightest contamination in a helium cylinder can disrupt test results and damage expensive equipment. On the other hand, for more general uses such as balloon decoration and exhibition displays, there is no need for heavy costs, and “balloon grade helium” performs well. Sharing the exact details of your process with the Bonyan Gas sales team is the most efficient way to get the best expert-recommended grade.
Grade 5.0
Grade 5.5
Grade 6.0

Industrial safety and storage of helium gas
Helium is inert and non-flammable, but because of its very low density it can quickly displace the oxygen in enclosed industrial spaces and cause a risk of asphyxiation, without any warning smell or color. Proper ventilation and staff awareness of this hazard are therefore essential for working safely with helium.

Wholesale supply for industries
For large industries, research centers, semiconductor manufacturers and organizations with continuous consumption, wholesale and bulk helium supply with a dedicated schedule is available. This reduces supply costs and secures the supply chain for long-term projects.

It depends on factors such as the grade, order volume, global market conditions and access to helium sources.
Higher grades (5.5 and 6.0) have greater purity and are essential for sensitive processes such as semiconductors and gas chromatography; lower grades are enough for general industrial use.
