Introduction

Steel vertical tanks (PBC) are one of the most popular and common types of capacitive equipment. They are widely used in a wide variety of industries. In particular, they are used to store various substances in the liquid phase. These can be production products that are awaiting transportation, or vice versa, source materials.

It is difficult to name at least one branch of heavy industry where vertical cylindrical tanks would not be in demand. In the oil, oil and gas processing industries, as well as in petrochemicals, vertical reservoirs for oil products are most often used. They contain both crude oil and refinery products. Also in these tanks are stored intermediate products of cracking and reforming, chemical synthesis, and so on.

There are quite a wide variety of types and types of vertical tanks. They differ in a number of features, including wall thickness, bottom shape, the presence of additional nozzles and valves, and so on. The use of this vertical tank is limited by its technical characteristics and the scope recommended by the manufacturer. Vertical tanks are manufactured to perform specific tasks and store strictly defined types of liquids. However, the purpose of the vertical tanks may vary sufficiently wide when it comes to liquids with similar properties.

The main characteristic on which to rely when buying is the volume of the tank.

The description of the vertical tank must contain an indication of the main characteristics, as well as indications of the operating conditions.

All calculations were made according to the method of limit states according to SNiP 22381 * and SNiP 2.01.0785 Norms allow you to choose the steel class for tank elements, recommend the type of welding and welding materials, installation method, design solutions, types of foundations and bases. It also gives instructions on the protection of tanks from corrosion, environmental protection, fire prevention measures.

Conclusion

The tank, for storage of winter diesel fuel, is designed in compliance with the specified data in the terms of reference, in compliance with all fire safety standards. Optimal geometrical dimensions of PBC 2000 m3 were selected, the condition of strength and stability was checked - the tank meets all requirements. All loads acting on the tank are calculated. All conditions are considered when designing the ring edge. The process equipment required for normal operation of the process tank is selected.
