What is a vessel? Types of vessels and their purpose. Water tanks, plastic

Almost every branch of the national economy today uses this kind of container, like a vessel. This container participates in various production cycles, participates in the storage of gases, liquids, as well as their transportation. In everyday life this kind of containers is also in demand. There are quite a few directions for their application.

What is the vessel, it is necessary to consider in more detail. This will allow you to understand their great diversity. Each type of container has a specific purpose. In the process of operating the vessels, this must be taken into account. Safety of people depends on knowledge of the rules of using blood vessels. Therefore, in the question of the purpose of each species, it is necessary to delve into details.

general characteristics

To understand what a vessel is, first of all it is necessary to understand the definition of this concept. Everything is extremely simple. A container is a hermetically sealed container of a very different application profile.

Such objects can be made of a variety of materials. The most commonly used glass, plastic and metal.

When studying what a vessel is, one should also say that they are used both for carrying out various chemical, technological processes, and for transporting or storing various substances.

Depending on the purpose, the containers may have different shapes. The configuration of the vessels can be very simple. But there are also quite complex products in their construction.

Since there may be substance inside the containers, there is a different pressure on the walls of the sealed container. Therefore, when operating vessels, it is necessary to adhere to the relevant safety rules.

Simple forms of blood vessels

Vessels, depending on the form, as well as the peculiarities of operation, are divided into certain types. Most often, simple containers can be made in the form of a cylinder, a barrel or a cistern.

A cylindrical vessel that can be rolled from one place to another is called a barrel. Its ends are flat, which allows you to put containers without supports. Often they are used to store liquid substances or transport them.

The cylinder has one or two necks. They are installed flanges, valves, fittings or other elements of the valves. They store, transport gases, liquids under pressure, and also with a vacuum inside.

A tank is a vessel with a special design, which allows transportation of containers to the required distances. In this case, trains, trucks and other means of transportation are used.

Vessels for domestic use

Most often for domestic purposes, water tanks are used . Plastic and glass bottles, cans are known to everyone. In addition to various sealed dishes, sanitary containers and tanks are used. In them water can be in a cold and heated state.

The pressure in these vessels is very different. When manufacturing similar containers, the manufacturer must provide them with a certain set of characteristics.

If water is to be used for drinking purposes, the vessels made of plastic, glass should have food tolerance, do not contain poisonous or harmful impurities.

When storing substances that have a chemical or thermal effect on the walls of the vessel, the container must be made of strong, thick materials that are resistant to destruction.

Pressure receptacles

Particular interest from the rules of safe use of the objects presented is caused by pressure vessels. To their application are very scrupulous. After all, if used improperly, their walls are quickly destroyed, which can result in an explosion, the flow of hot or chemically active substances outwards.

Therefore, a vessel with water, ammonia, gas and other substances should be selected strictly in accordance with the conditions of their application. In the production and in the home, special rules have been developed that explain how to properly operate all kinds of vessels. When buying these products, you should always read the manufacturer's instructions. It clearly specifies the operating conditions and safety rules that the user must adhere to.

Types of pressure vessels

To the list of vessels that are in the process of application under high pressure, there are several main types. First of all, they are compressors and autoclaves. Also here are steam boilers and water heaters.

For example, if two identical vessels are connected by a tube, it can be a radiator. When the liquid is heated, it presses against the walls of these containers. Therefore, for each type of heating (central, autonomous), select radiators of the appropriate type.

Also in this group are cylinders containing gaseous substances. Before launching into operation at enterprises and at home, the vessels presented are tested accordingly. For this, certain services are responsible. This helps to avoid accidents.

This group includes water tanks, which are heated above 110 ° C. Liquids or gaseous substances can exceed the boiling point and create a pressure of more than 0.7 MPa. Some vessels are used for storage and transportation of bulk components.

Water Tanks

At normal and high pressure, various water tanks are used. Plastic vessels are most often used for cold water. When adding a special reinforcement or reinforcing components, plastic containers for hot water and boiling water are made.

For technical and drinking liquids, plastic for containers is made from special components. The range of shapes, sizes and applications of such tanks is incredibly wide. This is due to the price of the material presented, as well as its properties.

Glass is most often used to make small vessels containing food. In this area, such material exceeds the quality of plastic. In glass containers or other vessels, food, water retain their original qualities much longer.

Metal containers

For technical purposes, metal vessels are most often used. They are able to withstand very high pressure and heat. Therefore, to store, transport, heat a large volume of water, a plastic glass jar is practically not used.

To provide agriculture, settlements and individual consumers with technical or drinking resources, reservoirs, pressure towers with a volume of 15 to 200 cubic meters are built. M.

For private use of water, vessels are used in the form of boilers, boilers, heating systems, etc. Metal containers are treated in various ways. This allows to reduce the process of formation of corrosion and destruction of blood vessels. When creating such products use a huge number of metal alloys.

Protection system

Since the existing types of pressure vessels are of some degree of danger, they need some protection. Such tanks are equipped with a pressure gauge and a thermometer. This allows you to monitor the internal state of substances.

Various safety devices are also used, which allow to relieve excessive pressure when the temperature in the vessel rises. Depending on the type of container, lever-load or spring devices, impulse varieties, as well as specimens with a collapsing membrane can be used. This allows us to protect the user from unforeseen situations.

Having considered what a vessel is and also what are their features, it is possible to correctly apply such containers. The range of their purpose is wide. Therefore, there are many types of vessels today. Apply them strictly in accordance with the rules of operation. This will avoid unpleasant situations at work or at home.
