Argon (Ar)

• Colorless gas
• Odorless
• Non-flammable
• Heavier than air
• Has a suffocating effect on humans.

Pure argon is used in various industries:

• in welding works on any metals as a shielding gas;
• argon is used to fill hollow sections of modern plastic windows;
• this inert gas is used as a flame suppressant in firefighting systems;
• argon is also used in the food industry to extend the shelf life of products.

Based on the degree of purification and the presence of impurities, three grades of technical argon are commonly referred to.

• high-purity argon (HP). Argon content 99.998%. High-purity gas is used for work with stainless steel, as well as titanium and magnesium alloys;
• superior-grade argon (SG). Inert gas content 99.993%. This type is most commonly used for welding most metals;
• first-grade argon. Argon content 99.98%. In metallurgy, it is used to purify molten metals. Additionally, first-grade gas is used to fill the cavities of double-glazed units in multi-chamber plastic windows.

In addition to technical argon with purity levels up to 99.998%, there is special purity argon with levels of 5.0 and 6.0 (99.999% and 99.9999%, respectively). Special purity gases are necessary for scientific research, as well as for use in laser installations and metrology. Important! Filling cylinders with pure argon of grades 5.0, 5.5, and 6.0 is only allowed when using exclusively clean containers. When receiving cylinders for filling or exchange, it is necessary to provide a cylinder with residual pressure. In the absence of residual pressure, the necessary service – thermal vacuum desorption of the cylinders – will be offered to you. Argon belongs to class 2 of hazardous materials. Gas cylinders are safe for use and transportation. However, a high concentration of argon in the air may cause nausea, dizziness, or loss of consciousness. When working with argon in enclosed spaces, it is necessary to monitor the oxygen level. The minimum oxygen level is 19%. In argon cylinders, the pressure according to GOST is 150 atmospheres. Our production facilities allow us to fill cylinders and monoblocks up to 300 atmospheres. They are marked with the necessary technical data: date of manufacture and certification, volume, weight, and manufacturer’s mark. A cylinder with pure argon is painted gray with a green label saying "Argon." Gas under pressure, colorless, odorless, asphyxiating, slightly lighter than air. Nitrogen gas can be of several purity grades, which indicate the amount of this gas in the total mixture. There are three grades: standard, high, and ultra-high. High purity grade, or nitrogen 5.0. This grade indicates a gas purity of 99.999%. That is, out of a million parts of the mixture, 10 contain oxygen as a residue. Pure nitrogen grade 5.0 is used in various industries: to create an inert atmosphere for the storage, production, or transportation of products with high oxidizability; to preserve enclosed vessels and pipelines; in scientific activities; in metallurgy; in medicine. Frozen tissues and blood are stored in liquid nitrogen; in the chemical industry. Nitrogen is used to produce paints, solvents, and coatings; in agriculture. Fertilizers are made from pure nitrogen. {ITEM}{~ID}271{/~ID}{~UF_PREVIEWTEXT}Gas under pressure, colorless, odorless, asphyxiating, slightly lighter than air.{/~UF_PREVIEWTEXT}{~UF_REDUCTOR}Brass two-stage for clean gases{/~UF_REDUCTOR}{~UF_MAIN_PROPERTIES}Gas under pressure, colorless, odorless, asphyxiating, slightly lighter than air.{/~UF_MAIN_PROPERTIES}{~UF_APPLICATION_TEXT}

Nitrogen has a wide range of applications in various industrial sectors. For example:

• creating an inert atmosphere during transportation, storage
• metal processing under high temperature conditions
• conserving metal pipes
• chromatography (in medicine)
• research purposes
• facilities dealing with food products and beverages
• metal processing in the metallurgy industry.

During transportation, pure nitrogen gas is classified as dangerous cargo. In gaseous form, this substance may be transported by any type of land transport (road, rail, or water). Inert gas is transported in steel cylinders under pressure. All containers must comply with strict GOST standards.

During movement or storage, cylinders with gas should not be exposed to heating, falling, or any other impacts. Overheating or severe impact poses a risk of explosion.

Nitrogen is not harmful to the environment or ecology. It is non-toxic. However, inhaling a large amount of the substance can be life-threatening. When working with nitrogen, it is necessary to monitor the oxygen level in the surrounding space. It should not be below 19%.
