Oxygen Gas
Oxygen GasOxygen (O2), as the most vital thermal and chemical accelerator, plays a key role in improving the efficiency of modern industries. It is used in heavy industries such as steelmaking, petrochemicals and thermal cutting to raise furnace temperatures and speed up operations, and it is an essential part of water treatment and medical centers. Understanding these needs, Bonyan Gas supplies industrial and medical oxygen grades with guaranteed purity and quality.
Oxygen gas grades
Oxygen gas is produced and supplied in different purity levels. The reason for this variety is that different industries and applications have different purity needs. For example, the purity required in a sensitive laboratory process is not the same as that used in many general industrial applications. Choosing the right grade not only affects process quality but can also optimize operating costs. That’s why we recommend carefully reviewing the type of use and the purity required before buying, so you can choose the best option.
Grade 2.5 and above
Grade 4.0
Grade 5.0

Oxygen gas supply and delivery method
Supply as a full tank: ready-to-use gas is delivered to you; suitable for urgent needs.
For tank/cylinder specifications: Buy a ready oxygen cylinder ↗
Refilling existing tanks: refilling your current tank is usually more economical than replacing the whole cylinder.
Wholesale and bulk supply: large industries such as petrochemicals, steelmaking and chemical plants need a stable, large flow of industrial gases because of the scale of their operations. Our wholesale supply service is designed around your plant’s structure and consumption pattern, shortening order cycles, simplifying storage and keeping your production lines secure with uninterrupted gas supply.
Oxygen gas safety tips
Oxygen is not flammable in itself, but as a strong oxidizer it greatly intensifies the combustion of other materials. Direct contact of this gas with combustible materials, especially hydrocarbons such as oil and grease, dramatically increases the risk of fire and explosion.
Therefore, to store oxygen safely, cylinders must be kept in a well-ventilated place, away from sunlight, heat sources, sparks and greasy materials. In addition, oxygen for therapeutic and medical use must only be used under the direct supervision of trained staff or as prescribed by a doctor.
