Selection and maintenance of storage containers. Equipment

The choice of container volume is determined by the needs of the customer. Cylinders with low values ​​are used for domestic needs and simple short-term construction. Large containers are designed specifically for stationary use in factories and enterprises, and are not intended for frequent movements and transportation. Small containers are not equipped with valves. Medium-sized cylinders can be equipped and completed with:

• Shoes
• Valves
• Rings
• Caps

At the customer's request, containers for storing and transporting liquefied substances are made with neck dimensions different from the current GOST 949-73. New equipment, at the buyer's request, may not be painted by the manufacturer.

The completeness is indicated by the customer in a specific questionnaire. Equipment with additional parts is indicated in notes with justification. Standardly supplied with the cylinder:

• Neck ring
• shoe
• Flow valve
• Safety cap

The outer wall must be painted with black paint with the yellow inscription “Carbon Dioxide”. Every 5 years all equipment is subject to technical inspection.

Maintenance of equipment for the transportation and storage of carbon dioxide is carried out by organizations that have permission for this type of activity. Before putting into operation, all cylinders must be painted with enamel, oil or nitro paint. After the procedure, containers for carbon dioxide are marked according to the rules of the current GOST.

Purpose and equipment

GOST 949-73 requires storing and transporting carbon dioxide in specialized carbon dioxide steel containers (cylinders). It is allowed to use new containers and used vessels that have successfully passed technical inspection and testing. Verification procedures are carried out during the recertification of cylinders.

The set of new carbon dioxide tanks includes the following parts:

• steel flask for storing carbon dioxide;
• gas valve weighing 0.5 kg;
• rubber transport ring (2 pcs.);
• support device (shoe) weighing 5.2 kg;
• steel or fiberglass safety cap weighing 0.5 kg;
• neck attachment weighing 0.3 kg.

As a material for the manufacture of carbon dioxide cylinders, regulations require the use of high-quality structural carbon or alloy steel. As a rule, the initial blanks in production are seamless pipes. Black paint is used to paint the walls of the container. The stamp “CARBON ACID” is used as marking (applied with yellow enamel).

GOST requires each carbon dioxide cylinder to be equipped with a passport. As a rule, it is located at the top of the container. To apply the necessary data, the impact stamping method is used. The area of ​​the wall where the information is located is first cleaned to a metallic shine. The upper permissible limit of working pressure is no more than 19.6 MPa. The weight of the cylinder is indicated without taking into account the weight of the components.

Carbon dioxide cylinders for welding: which one to choose?

Beginners or handicraft welders, choosing comfortable 10 or 20-liter carbon dioxide cylinders, are faced with the problem of refueling, since the equipment of most gas stations is designed for 40-liter containers.

Did you know about this? We also say “no,” which means we’ll figure it out together.

High-quality certified cylinders offered by https://safegas.com.ua/ru/gazovye-ballony/ballony-uglekislotnye-co2/ are produced in various volumes (from 5 to 40 liters) and are in demand for both domestic and industrial needs production.

Welding cylinders: selection criteria

1. If you use a welding mixture or argon when performing welding work, then you have a small choice - only 40-liter cylinders, but you can always ask the firefighters about the possibility of refilling small containers with carbon dioxide - as part of their duty, they often have to refill fire extinguishers .

2. The body of the cylinder must be painted black and marked with a bright yellow inscription with the name of the gas. When purchasing, do not forget to check for the presence of a “passport” - it is extruded on the top of the container and contains data on weight, volume, maximum operating pressure, manufacturer, technical control marks, etc.

3. The gearbox (regulator) plays a great role in the quality of welding and saving carbon dioxide. According to professionals, a dial regulator with a calibrated nozzle most consistently maintains pressure and saves gas, while regulators with a rotameter only reduce the gas pressure to the required value.

Performance characteristics of cylinders

1. The empty weight of a 40-liter carbon steel container is 65 kg, while an alloy steel container is lighter - about 55 kg.

2. The service life of the cylinder is 20 years (unless otherwise specified by the manufacturer), but for safety reasons, once every five years the cylinder is taken for mandatory inspection and certification, based on the results of which a test report is issued. 3. When transporting, the cylinder must be in a horizontal position; before starting work, the rest period is at least 30 minutes. 4. During operation, carbon dioxide cylinders should not be located near heating devices or in direct sunlight.

When working with carbon dioxide cylinders, safety is first and foremost important, so do not hesitate to request certificates of conformity and test reports, check the passports and the quality of manufacture of the cylinders.

Transportation and storage

Carbon dioxide turns into a liquid state at elevated pressure; it is stored in cylinders in a liquefied state, since this is more economical than in a gas state. It is forbidden to store cylinders near heating devices, and also to allow the valve to freeze. Cylinders should be protected from impacts and mechanical compression. It is recommended to transport cylinders in a horizontal position or in a vertical position if there is a special holding device.

Carbon dioxide cylinders are one of the indispensable elements in the production and sale of foamy drinks. If you are the owner of a small brewery or beer bar, all you need to do is buy a 5 or 10 liter CO2 cylinder; it is compact in size and can be easily installed even in a limited area (for example, under a bar counter). Good luck in your business!

Use of carbon dioxide in cylinders

1. Medicine and pharmaceuticals (production of medicines, carboxytherapy in cosmetology, use in operations in cryosurgery).
2. Construction industry (welding, production of porous building materials).
3. Chemical industry (perfumery production, etc.)
4. Fire extinguishing systems (fire extinguishers).
5. Agriculture (processing of fruits, berries, grains, nuts before storing to prevent damage by rodents and diseases).
6. Food industry.

Storage and safety precautions

A carbon dioxide gas cylinder is not particularly dangerous if it is completely sealed. Carbon dioxide does not burn or explode; on the contrary, it prevents combustion. It is no coincidence that it is used when extinguishing fires. However, this gas can still cause harm. Once distributed in the atmosphere, carbon dioxide causes suffocation. It does not support breathing processes.

That is why gas cylinders with such contents are refilled only after checking the vessels. If the containers are damaged, carbon dioxide can spread into the air. The contents of black cylinders pose the greatest danger to people who are in a poorly ventilated area.

First of all, the valves of the cylinders need to be checked. If they are damaged, then the components must be urgently replaced. Otherwise, high pressure gas will begin to penetrate into the air. In the event of a leak, it is important to remember that carbon dioxide concentrates closer to the ground or floor.

Areas of use

Carbon dioxide has many different uses. The most famous are the following:

• For medical purposes, tissue preservation may require freezing. Liquefied carbon dioxide can be used for this purpose. If it is released under conditions of room temperature and pressure, it takes the form of white flakes, taking a lot of heat.
• In the perfume industry, liquefied carbon dioxide helps produce rich-smelling perfumes. This technology allows you to avoid the unpleasant specific odor that may appear in some cases during such procedures.
• Carbon dioxide allows you to create refreshing carbonated drinks. It is also used as an important ingredient in some cocktails.
• When repairs are made or construction work is carried out, welding work is often required. Carbon dioxide allows them to be performed without the formation of additional carbon deposits, which significantly improves the result of the work.
• Carbon dioxide fire extinguishers are highly effective in extinguishing fires. Their important advantage is the ability to be used when extinguishing electrical equipment, since in this case the risk of a short circuit is eliminated. If you are extinguishing objects that may deteriorate when extinguished with water, then carbon dioxide fire extinguishers will be a good choice.
• The use of dry carbon dioxide baths is an effective medical procedure. The gas helps to expand pores and regenerate skin cells. The procedure has virtually no contraindications. It can be used even after a heart attack, as it does not create excessive stress on the body.

Cylinders are usually divided into categories according to their volume. Those that have no more than 20 liters are considered small, from 20 to 40 are considered medium, and those exceeding 40 liters are considered large.
