Argon is a gas classified as inert gas. Inert. It is used broadly in almost all of the fields of industry. In terms of share in the Earth atmosphere, argon is the third most common after nitrogen and oxygen.
Argon is produced by low-temperature air separation. This means that the air is divided into its components: nitrogen and oxygen. Besides these two gases, argon is also recovered individually. Since the mass share of argon in the atmospheric air is at or below 1%, the cost of this gas in pure form is higher than the cost of the others..

Pure argon is used in various industries:

in welding work on any metals as a shielding gas;
argon fills the hollow sections of modern plastic windows;
this inert gas is used as a flame suppressor in firefighting systems;
argon is also used in food production to extend the shelf life of products.

Depending on the degree of purification and the presence of impurities, three grades of technical argon are commonly distinguished.

High-purity argon (HP). Argon content 99.998%. High-purity gas is used in work with stainless steel, as well as titanium and magnesium alloys;
Superior grade argon (SG). Inert gas content 99.993%. This type is most often used in welding most metals;
First-grade argon. Argon content 99.98%. In metallurgy, it is used to purify molten metals. In addition, first-grade gas is used to fill the cavities of insulating glass units in multi-chamber plastic windows.

In addition to technical argon with purity levels up to 99.998%, there is special purity argon with grades 5.0 and 6.0 (99.999% and 99.9999%, respectively). Special purity gases are required for scientific research, as well as for use in laser systems and metrology. Important! Filling cylinders with pure argon grades 5.0, 5.5, and 6.0 is only permitted when using exclusively clean containers. When submitting cylinders for filling or exchange, the cylinder must have residual pressure. If there is no residual pressure, the necessary service—thermo-vacuum desorption of the cylinders—will be offered to you.

Argon belongs to Class 2 hazardous materials. Gas cylinders are safe for use and transport. However, increased concentrations of argon in the air can cause nausea, dizziness, or loss of consciousness. When working with argon in enclosed spaces, it is essential to monitor oxygen levels. The minimum oxygen level is 19%. Cylinders with argon, according to GOST standards, have a pressure of 150 atmospheres. Our production facilities allow us to fill cylinders and monoblocks up to 300 atmospheres. Necessary technical data is marked on them: the date of manufacture and certification, volume, weight, and manufacturer's mark. A cylinder with pure argon is painted gray with a green inscription "Argon".
