Almost every branch of the national economy today uses such a type of container as a vessel. This tank participates in various production cycles, participates in the processes of storage of gases, liquids, as well as their transportation. In everyday life, this type of capacity is also in demand. There are quite a few directions of their application.
What is a vessel, you need to consider in more detail. This will make it possible to understand their great variety. Each type of tank has a specific purpose. During the operation of the vessels, this must be taken into account. The safety of people depends on knowledge of the rules for using vessels. Therefore, the question of the purpose of each variety must be examined in more detail.
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 vessel is a hermetically sealed container of a very different application profile.
Such objects can be made of a variety of materials. Most often used glass, plastic and metal.
Studying what a vessel is, it should also be said that they are used both for carrying out various chemical, technological processes, and for transporting or storing various substances.
Depending on the purpose, the presented containers may have a different shape. The configuration of the vessels can be very simple. But there are also quite complex in design products.
Since there may be substance inside the containers, different pressure is exerted 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 features of operation, are divided into certain types. Most often, simple containers can be made in the form of a cylinder, barrel or tank.
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 the container without supports. Often they are used to store liquid substances or transport them.
The cylinder has one or two necks. They install flanges, valves, fittings or other elements of valves. They store, transport gases, liquids under pressure, as well as with vacuum inside.
A cistern is a vessel with a special design that allows you to transport containers to the required distances. In this case, trains, trucks and other means of transportation are used.
Domestic vessels
Most often for domestic purposes, water containers 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 such vessels is very different. In the manufacture of such containers, the manufacturer must endow them with a certain set of characteristics.
If water will be used for drinking purposes, vessels made of plastic, glass should have food tolerance, not contain toxic or harmful impurities.
When storing substances that have a chemical or thermal effect on the walls of the vessel, the container should be made of strong, thick materials that are resistant to destruction.
Pressure vessels
Of particular interest from the rules for the safe use of the items presented are pressure vessels. Their use is very scrupulous. Indeed, with improper use, their walls quickly collapse, which can result in an explosion, leakage of hot or chemically active substances to the outside.
Therefore, a vessel with water, ammonia, gas and other substances should be selected strictly in accordance with the conditions of their use. In factories and in everyday life, special rules have been developed that explain how to properly operate all kinds of vessels. When buying such products, you should definitely study the manufacturer's instructions. It clearly indicates the operating conditions and safety rules that the user must adhere to.
Types of pressure vessels
The list of vessels that are in the process of application under high pressure includes several main types. First of all, these are compressors and autoclaves. Also included are steam boilers and water heating appliances.
For example, if two identical vessels are connected by a tube, it may be a radiator. When the liquid is heated, it presses on the walls of these containers. Therefore, for each type of heating (central, autonomous), radiators of the corresponding type are selected.
Also in this group are cylinders that contain gaseous substances. Before putting into operation at the enterprises and at home, the vessels presented are tested accordingly. Certain services are responsible for this. This avoids accidents.
This group includes containers for water, which is 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 containers are operated. Plastic vessels are most often used for cold water. When special reinforcement or strength-enhancing components are added, plastic vessels 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 is superior in quality to plastic. In glass containers or other vessels, food products and water retain their original qualities for much longer.
Metal containers
For technical purposes, metal vessels are most often used. They are able to withstand very high pressure and heat. Therefore, for storage, transportation, heating of a large volume of water, a plastic, glass vessel is practically not used.
To provide agriculture, settlements and individual consumers with technical or drinking resources, tanks, pressure towers with a volume of 15 to 200 cubic meters are being built. m
For private use of water, vessels are used in the form of boilers, boilers, heating systems, etc. Metal containers are processed in various ways. This reduces the process of corrosion and destruction of blood vessels. When creating such products, a huge number of metal alloys are used.
Protection system
Since existing types of vessels operating under pressure differ in a certain degree of danger, they need some protection. Such tanks are equipped with a manometer and a thermometer. This allows you to control the internal state of substances.
Various safety devices are also used 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 you to protect the user from unforeseen situations.
Having considered what a vessel is, and also what their features are, it is possible to correctly apply such containers. The range of their destination is wide. Therefore, there are a huge number of vessel types today. They must be used strictly in accordance with the operating rules. This will avoid unpleasant situations in the workplace or at home.
