Argon and HF argon gas in cylinders

It is profitable to buy argon in Ulyanovsk from the industrial company TRUSTGAZ

We are a manufacturer of technical cryogenic gases and offer our customers high quality argon-filled cylinders at a low price that can only be offered by the manufacturer.

Areas of application of the substance

Ar is used in the following fields of activity:

• in the metallurgical industry: not a single technological process of steel smelting can be completed without this substance. It is involved in the cooling process of the metal, accelerates the melting process of the introduced ingredients, removes non-metallic compounds, etc. High-quality alloys, such as titanium and rare earth metals, zirconium, tungsten, require a protective argon environment to implement their processing technology.
• in metalworking, Ar creates a protective environment during thermal exposure, using contact and laser types of welding, and creates a protective curtain when welding with an electric arc. This gas acts as a plasma-forming substance in units intended for welding and cutting aluminum, magnesium stainless alloys, rare metals, alloy and heat-resistant steel.
• in radio electronics, it creates an inert environment in equipment intended for plasma spraying processes, fills the space of gas-light advertising signs, and luminescent devices.
• in spectroscopic and metrological equipment it acts as a carrier, plasma-forming substance and is used for the production of gas analyzing equipment.

In addition, it is widely used in the engineering, mining, and construction sectors. The electric power industry uses Ar to fill special gas-charging lamp devices during the production of components and assemblies. For the chemical industry, the substance is indispensable for the creation of ultrapure substances, so the purity of the gas is of paramount importance. Even if the substance has a slight deviation from the required indicators of the corresponding state standard, the operating, analysis and testing conditions change significantly, which can lead to incorrect and unreliable results, as well as distortions and disruption of the normal functioning of expensive equipment. Therefore, it is very important to buy argon from a trusted manufacturer, who guarantees that the purity of the gas corresponds to the declared GOST parameters and properly conducts appropriate tests and laboratory studies on the quality of the products.

The main characteristics include its non-toxicity and non-explosiveness. However, inhaling the gas through the respiratory system can cause serious consequences for life and health. If you take even a few breaths, suffocation occurs. When inhaling 100% argon vapor, a person may lose consciousness, which after a certain time can even lead to death.

Due to the fact that argon weighs much more than air, it easily accumulates in poorly ventilated spaces, can settle near the floor, and accumulate in the internal space of installations that are used to obtain or transport Ar. Moreover, it can be in either a liquid or gaseous aggregate state.

Main advantage

Due to the fact that Ar is an inert gas and heavier than air, it creates reliable protection for metals and their alloys and almost completely eliminates the interaction of the surface with oxygen. The argon arc welding technique often involves the use of a specialized gas ball, which ensures guaranteed insulation of the weld.

Types of argon

This substance is supplied to the customer in two states: in the form of a gas and also in a liquid aggregate state. Transport delivery services can be carried out on trucks specially equipped for the transport of dangerous goods. Gas is pumped into specialized cylinders of various capacities that can withstand significant gas pressure.

Filling cylinders with argon

In the liquid state, it is filled into specialized vessels with powder, vacuum-powder, and multi-layer vacuum insulating protection. The volume of cryovessels varies depending on the customer's needs. Transportation of argon in cryovessels and cylinders is carried out only on specialized transport, taking into account all the rules for transporting high-risk cargo.

We offer to buy argon at affordable prices from the TRUSTGAZ company. Industrial gas can be purchased in the quantity required by the customer: from retail to wholesale quantities. The client exchanges empty containers for ones filled with cryogenic gas, thus selling argon in a gaseous state. We fill containers with gas, which is manufactured in accordance with the requirements of GOST 10157-79. In our warehouses we have cylinders available for release in volumes of five, ten, twenty and forty liters. The serviceability and reliability of each container is checked by our production specialists, who check them for leaks and do not allow the slightest possibility of gas leaks. If a defect is found, they are sent for additional inspection and are not allowed for sale. Additionally, we provide repair services for gas cylinders (cylinders) and carry out technical examination. For these purposes, our production is equipped with all the necessary tools and installations. Permission was received from Rostechnadzor to assign the “73P” brand.

Argon and HF argon gas in cylinders

You can buy argon in cylinders of 40 liters and on request 5, 10 and 20 liters, fill the cylinders with argon, and also buy liquid argon.

The scope of application of argon gas is extremely wide and in all areas of activity the result of the work performed directly depends on its quality.

Information:

The use of argon is due to its properties; it is used: in incandescent lamps, when filling the internal space of double-glazed windows, in the smelting of metals with special properties, for spectral analysis of the purity of materials in laser installations, in mechanical engineering and construction to protect the welding arc during electric welding of parts made of high-alloy steel, and also for electric welding of aluminum parts.

Gaseous and liquid argon is used as a protective medium when welding, cutting and melting active and rare metals and alloys based on aluminum, aluminum and magnesium alloys, stainless chromium-nickel heat-resistant alloys and alloy steels of various grades, as well as when refining metals in metallurgy. Argon is also the basis of protective gases in gas mixtures for semi-automatic and automatic electric arc welding. One of the ways to mitigate and eliminate the disadvantages of welding with a consumable electrode in a CO2 environment is to replace CO2 with protective gas mixtures.

Argon storage and transportation.

The rules for storage, packaging, transportation and labeling of containers with argon are provided for by GOST 26460-85.

Safety requirements.

Argon is not an explosive or toxic gas, but it is dangerous to living organisms. With prolonged exposure to argon on a living organism, the latter begins to experience asphyxia, loss of consciousness, pulse and death. First aid measures can include artificial respiration in cases where loss of consciousness has occurred, or it is enough to go outside if loss of consciousness has not yet occurred. Asphyxia, caused by inhaled air with a high concentration of argon, at the initial stage is accompanied by headache, dizziness, nausea and vomiting. Breathable air is considered to be air in which the volume fraction of oxygen is at least 19%. Argon can also accumulate in storage and packaging areas, which is why these areas need to be ventilated.

Liquid argon has a low boiling point and, in direct contact with the human body, causes frostbite to the skin and irritation of the mucous membranes. Working with liquid argon without a protective suit is prohibited and dangerous to the health of the worker working with liquid nitrogen. When carrying out repair work and inspection of previously used tanks and tanks for storing and transporting liquid argon, it is necessary to warm them up to a temperature equal to the ambient temperature and ensure the saturation of the internal volume with oxygen to the level of its normal concentration (at least 19% of the volume of the entire container).

Dependence of argon pressure on temperature during filling, transportation and storage of cylinders

Note:

When filling cylinders, as well as storing or transporting filled cylinders at temperatures exceeding those indicated in the table, the gas pressure in the cylinder should not exceed:

• at a temperature of +40 ºС - 15.0 MPa (153 kgf/cm²) for the operating pressure of the cylinder 14.7 MPa (150 kgf/cm²), 19.7 MPa (201 kgf/cm²) 19.6 MPa (200 kgf/cm²) )
• at a temperature of +50 ºС - 15.7 MPa (160 kgf/cm²) 14.7 MPa (150 kgf/cm²), 20.6 MPa (210 kgf/cm²) 19.6 MPa (200 kgf/cm²)

High purity argon - filling cylinders in Ulyanovsk

Ar HF is an inert gas that does not have any particular taste, smell, or color. It is 1.38 times the weight of air and reaches the boiling process at a subzero temperature of -185.9 degrees Celsius. Argon is produced industrially by separating air or residual ammonia gases that are formed during production.

Areas of use of substances with a high degree of purity

Containers with this substance are used to create a protective shell necessary for carrying out a variety of technological manipulations, such as welding, melting and cutting processes of rare earth materials and their alloys, and spectral analysis of the chemical composition of metals. These include aluminum, magnesium, heat-resistant nickel, chromium, alloy compounds with anti-corrosion properties, and semiconductor products. In the last ten years, HF argon has been used to fill incandescent light bulbs and discharge tubes.

It is best to buy argon in cylinders, as well as rent containers for industrial gases, from a specialized industrial organization in Ulyanovsk. Order transportation services by calling the contact number indicating the exact address and desired delivery time period. If necessary, our specialists will carry out repairs and extend the service life of the customer’s tanks, and it is also possible to undergo recertification of cylinders with the issuance of all necessary documentation.

Argon HF 99.998% is an inert substance that is not capable of combustion and does not have a toxic effect on humans when working with this substance, taking into account precautions. To produce this gas, air is separated into nitrogen and oxygen, that is, air is rectified at low temperatures, resulting in a cryogenic product - gas in the form of a liquid state at very low temperatures. Due to the fact that the share of argon in air is only a little 1%, the price of this product is higher than that of oxygen or nitrogen. sells high quality argon in Ulyanovsk at a low price.

High purity argon acts as a universal shielding gas during welding of a wide variety of metal joints. It is used by professionals who deal with welding tasks on a daily basis in the workplace and understand the effectiveness of such work in a high-purity shielding gas environment.

Argon

Argon gas is an element of the 18th group of the periodic table of chemical elements of the third period of the periodic system of chemical elements of D.I. Mendeleev, with atomic number 18. It is designated by the symbol Ar (from the Latin Argon). The third most abundant element in the earth's atmosphere (after nitrogen and oxygen) is 0.93% by volume. Argon is an inert monatomic gas without color, taste or smell.

Argon is heavier than air, density 1.78 kg/m3 at zero temperature and normal pressure. Boiling point -185.85°C..

Origin of name:

At the suggestion of Dr. Medan (chairman of the meeting at which the report on the discovery was made), Rayleigh and Ramsay gave the new gas the name “argon” (from another Greek - lazy, slow, inactive). This name emphasized the most important property of the element - its chemical inactivity.

Argon production:

In industry, argon is produced as a by-product during the large-scale separation of air into oxygen and nitrogen. At a temperature of -185.9 °C (88 Kelvin) argon condenses, at -189.4 °C (83 Kelvin) it crystallizes.

Due to the close boiling points of argon (88 K) and oxygen (90 K), the separation of these fractions by rectification is difficult. Argon is considered an impurity, allowed only in technical oxygen with a purity of 96%.

Application of Argon:

• in argon lasers;
• in incandescent lamps and when filling the internal space of double-glazed windows;
• as a protective medium when welding (arc, laser, contact, etc.) both metals (for example, titanium) and non-metals;
• as a plasma generator in plasmatrons for welding and cutting;
• in the food industry, argon is registered as a food additive E938, as a propellant and packaging gas;
• as a fire extinguishing agent in gas fire extinguishing installations;
• in medicine during operations to clean air and cuts, since argon does not form chemical compounds at room temperature;
• as part of the atmosphere of the Mars-500 experiment to reduce oxygen levels to prevent fire on board the spacecraft when traveling to Mars;
• due to its low thermal conductivity, argon is used in diving to inflate dry wetsuits, but there are a number of disadvantages, for example, the high price of gas (in addition, a separate system for argon is needed);
• in chemical synthesis to create an inert atmosphere when working with compounds that are unstable in air.

Biological role of argon:

Argon plays no significant biological role.

Physiological action

Inert gases have a physiological effect, which is manifested in their narcotic effect on the body. The narcotic effect of inhaling argon appears only at barometric pressure above 0.2 MPa. In 2014, WADA recognized argon as a doping drug.

High concentrations of argon in the inhaled air can cause dizziness, nausea, vomiting, loss of consciousness and death from asphyxia (as a result of oxygen deprivation).

Medical argon:

Medical argon is used in surgery as an inert gas for tissue coagulation. Argon plasma coagulation operations are almost bloodless.

In anesthesiology, high-purity argon is used in the preparation of respiratory mixtures. A mixture of oxygen and argon enriches the blood with oxygen and does not dry out the mucous membrane when breathing. It is also used during operations to clean air and cuts.

Argon is no less widely used in therapy. An oxygen-argon mixture is used in the rehabilitation of the body after intoxication; to increase the body's immune defenses; for the prevention of fetal hypoxia during pregnancy; to increase vitality, mental and physical performance; for effective hangover relief.

It is impossible not to note the positive effects of inhalation of an argon-oxygen mixture in the treatment of hypertension, otolaryngeal diseases, in restoring potency and increasing reproductive function. And this is not a complete list!

Danger to humans:

Does not have a hazardous impact on the environment. Argon gas is heavier than air and can accumulate in poorly ventilated areas near the floor. This reduces the oxygen content in the air, which causes oxygen deficiency and suffocation. Liquid – a low-boiling liquid that can cause frostbite to the skin and damage to the mucous membrane of the eyes.

Argon transportation:

Transported by all modes of transport in accordance with the rules for the transportation of dangerous goods in force for this type of transport. Argon gas is transported in steel cylinders (GOST 949-73) of gray or black color under a pressure of 150 kgf/cm2. For transportation by road, medium-volume cylinders are placed in special metal containers (pallets). Liquid argon is poured into special tanks with powder, vacuum-powder or vacuum-multilayer insulation intended for the transportation of liquid argon.
