Vertical steel tanks (VSTs) are used to store a variety of liquids in industrial facilities, from oil to water. Their installation requires a serious approach, as it is important to consider many factors, including safety, materials, and design specifics. In this article, we will tell you how to design and install such a tank so that it is reliable and durable.
Technical process of manufacturing a tank
The table below outlines the main stages of tank assembly, describing the key operations and controls required to ensure the reliability and safety of the structure.
RVS project planning
- Purpose of the tank
Before you begin, you need to clearly define what the tank will be used for. Different liquids require different material requirements. For example, if the tank will be used for oil, corrosion-resistant materials and careful protection against possible leaks are required. - Material selection
One of the most important decisions is the choice of steel. For RVS, special grades of steel resistant to external influences are usually used, such as grade 09G2S, which is widely used in Ukraine. This will ensure the durability and strength of the structure. Steel must comply with DSTU standards so that the tank meets safety requirements. - Structural design
Engineers calculate the loads that the tank will be subjected to. This includes the weight of the liquid, pressure on the walls, wind effects, and even the possibility of earthquakes. Based on these calculations, a design is created with drawings that specify all the tank parameters.
Tank installation
- Foundation preparation
For the tank to stand securely, it is necessary to make a high-quality foundation. It must be even, stable and strong enough to withstand the weight of the tank with liquid. Usually, reinforced concrete foundations are used for this, which are laid taking into account the characteristics of the soil. - Tank assembly
First, the bottom of the tank is installed. Then, the walls are mounted in stages and welded to each other. After that, the roof is installed. Each stage requires quality control of the welding to avoid leaks and ensure the tightness of the structure. - Inspection and testing
After assembly is complete, tests are carried out. One method is hydraulic testing. The tank is filled with water and checked for leaks. This allows you to identify possible weak spots in the welds and eliminate them in a timely manner.
Final stage
- Anti-corrosion protection
After the tests, a special coating is applied to the tank that protects the metal from rust. This can be epoxy paint or another material that extends the life of the tank and protects it from external influences. - Documentation and commissioning
When all work is completed, the tank undergoes final inspections. Based on the tests and inspections, a facility passport is drawn up, which indicates all the characteristics and test results. After that, the tank is ready for use.
Conclusion
Creating a vertical steel tank is a complex process that requires compliance with all standards and regulations. But if everything is done correctly at each stage, the tank will last for many years and provide safe storage of liquids. It is important not only to comply with technical standards, but also to carry out regular inspections and maintenance to extend its service life.
