New carbon dioxide cylinder with a flat bottom, 5 liters with valve VK-94-01 with outlet G3/4

Carbon dioxide cylinder (volume 40 liters)

To transport carbon dioxide and store it, special cylinders made of alloy or carbon steel and withstand high pressure are used. GOST 949-73, currently in force in Ukraine, defines the requirements for the technical parameters of these containers.

Most often, cylinders are used that hold 40 liters or approximately 20 - 24 kilograms of carbon dioxide, equipped with a brass valve. The diameter of such vessels is two hundred and nineteen centimeters. The working pressure of these containers can take on slightly different values ​​for different types of cylinders, depending on the wall thickness, body length and material of the vessel.

Parameters of a carbon dioxide cylinder holding 40 liters of CO2. (according to the USSR State Standard 949-73 “Steel cylinders of small and medium volume for gases. Technical conditions”).

When weighing such cylinders, the weight of parts such as rings, shoes, caps and valves is not always taken into account. Therefore, the weight of an empty container is indicated approximately. The weight of a full cylinder is approximately one hundred kilograms. According to the requirements of the accepted marking, these cylinders are painted black, and the inscriptions on them are made in yellow paint.

The scope of application of carbon dioxide, carbon dioxide, carbon dioxide or carbon dioxide is not limited to just one industry. In addition to everyone’s favorite carbonated mineral waters and sweet lemonades, “champagne in a stream” is very common. Using this method you can get sparkling wine much cheaper and faster than the traditional method allows. Carbon dioxide fire extinguishers of various types, sizes and power save things from fires that could be damaged when extinguished with water. For example, these could be museum values, complex equipment or important archives. Carbon dioxide is absolutely necessary in many industrial processes.

In the chemical industry, this gas is used to produce an excellent fertilizer - urea. And a disinfectant - salicylic acid, which also serves as a raw material for the production of aspirin. As well as methanol, which serves as a fuel additive. Scientists’ new proposal to produce plastics saturated with carbon dioxide opens up new possibilities for the use of this multifaceted material. For example, use safe, non-toxic liquid carbon dioxide as a pigment solvent when coloring contact lenses. Aquarists successfully use carbon dioxide to improve the growth of aquarium plants. Beekeepers use this gas when releasing a new swarm of bees. In the food industry, it is used in the form of “dry ice” to store food products such as ice cream.

Working with gases under high pressure always carries with it a certain, quite certain amount of danger. You should not increase your risk by relying on untested and therefore not very reliable suppliers.

Carbon dioxide cylinders 5 l, 10 l, 40 l, according to GOST 949-73

CO2 containers (cylinders) with a working volume of 5, 10 and 40 liters are designed for storage, transportation and technological distribution of carbon dioxide to consumers. New carbon dioxide cylinders must be equipped with:

• Oxygen valve VK, weighing 0.5 kg;
• Rubber transport ring – 2 pcs.;
• Support shoe, weighing 5.2 kg;
• A steel or re-certified cap, weighing 1.8 kg, or a fiberglass cap (safety), weighing 0.5 kg;
• Neck ring, weighing 0.3 kg.

The cylinders are made from the material “Structural high-quality carbon steel” grade 45D or “Structural alloy steel” grade 40KhGSA (cylinders with a capacity of 40 liters).

The body of the cylinder is painted black with the inscription “CARBON ACID” printed in yellow enamel. The weight of the cylinder is regulated without taking into account the weight of the valve, rubber rings, support shoe, safety cap and neck ring.

At the top of the cylinder there should be a “Carbon Dioxide Cylinder Passport”. Passport information is applied using the percussion method. In this case, the surface of the passport must be cleaned to a metallic shine and have an outer border in the form of a strip with an approximate width of 20-25 mm, applied with yellow enamel. The cylinder passport must contain the following information (from left to right along the perimeter of the intended circle):

• Date of manufacture of the cylinder, and the year of the next inspection;
• Working pressure “P”, MPa (kgf/cm2) and process hydraulic pressure “P” in MPa (kg/cm2);
• Capacity in liters;
• Empty cylinder weight in kilograms:
• The serial number of the cylinder and the product brand of the manufacturer;
• Brand of the company that carried out the Technical Examination of the cylinder;
• The mark of the Technical Control department of the cylinder manufacturer.

The thread in the neck of the cylinder is cut according to GOST 9909-81, and must meet the following requirements:

• Type – conical;
• The outer diameter in the plane of the neck end is 19.2 mm;
• The number of threads with a full thread profile is 7;
• There should be a thread left on the valve screwed into the neck - 2-5 and 1-2 turns of the visible threaded connection of the valve gland nut;
• The valve is installed on a sealing material, for example, a fluoroplastic sealant - FUM tape;

Warehousing and storage of cylinders is allowed both indoors and in open areas. In the latter case, the storage area must be equipped with a canopy that effectively protects the cylinders from direct rays of the sun and atmospheric factors: rain and snow.

Cylinder weight

When using, transporting and charging, it is necessary to monitor the presence of carbon dioxide in the cylinder. Weighing is used for this purpose. The mass of the following parts must be subtracted from the total weight:

• A vessel containing liquefied gas.
• The valve through which charging is carried out.
• Protective cap.
• Safety iron rings.
• If used, consideration must be given to how much the shoe weighs.

The entire structure is weighed, then the mass of the listed parts is subtracted. The remaining part tells how much carbon dioxide remains inside. The average weight of these nodes is:

• The weight of the ring is 300 g.
• The weight of the metal cap reaches 1.8 kg.
• The shoe typically weighs 5.2 kg.

The weight of the cylinder varies depending on its capacity and maximum permissible pressure. For example, at a pressure of up to 150 atm it will be 73 kg, and at 200 - 88 kg.

Typical use of systems

• Medicine during freezing in operating rooms;
• Food industry in the production of carbonated drinks and some types of cocktails;
• Perfume products to obtain a rich aroma without a specific chemical smell;
• In construction and repair for welding seams without the formation of additional carbon deposits.

The volume range of cylinders is presented in three categories: small forms (2, 5 and 10 liters); medium - (from 20 to 40 liters) and large - more than 40 liters. In industry, medium and large type cylinders are most often used due to the fact that they do not need to be constantly refilled and can be stored for a long time. Capacity certification takes place every 5 years.

has been on the market for a long time, therefore it provides products not only to industrial clients (mills, factories, construction corporations), but also to repair crews and service station workers.

Advantages

This container has become the main means of storing gases, and this applies not only to carbon dioxide, but also to other substances. All this became possible thanks to the advantages that its design has:

• The main advantage is that the container can be used repeatedly;
• Refilling CO2 cylinders is not the only procedure that can be carried out with cylinders, since after this other gases can be filled inside;
• The cylinders are strong and reliable enough to withstand falls, high temperatures and a long service life.

Difference in pressure parameters

Each carbon dioxide cylinder has two pressure indicators. The first is working pressure; in the process of complying with the technical rules of operation and transportation, this figure should not exceed 150 atm. The second type is test pressure, which is important at the stage of connecting the main system; this figure should not exceed 225 Atm. Note that for each volume the total permissible pressure indicator is maintained.

When ordering one or a batch of cylinders, you must ensure that you have a protective cap. According to the rules of storage and transportation, each cylinder is marked with the corresponding yellow inscription - Carbon dioxide.
