The design and operation of vertical steel tanks (VSTs) in Ukraine are subject to strict regulations. This is necessary to ensure the safety, durability and reliability of the tanks, especially when storing hazardous liquids such as oil, chemicals and fuel. In this article, we will consider the main standards that must be considered when designing and operating VSTs in Ukraine.
Basic regulations and standards
Before designing and operating vertical steel tanks (VSTs) in Ukraine, it is necessary to consider key standards that ensure safety and durability. Here are the main ones:
DSTU B EN 14015:2010
This is one of the key standards governing the design, installation and inspection of liquid storage tanks. It describes the requirements for materials, welding and leak testing. It is important that all these steps are strictly followed, as operational safety depends on it.
DSTU 2651:2010
This standard sets requirements for steel materials used in the manufacture of tanks. For example, steel grade 09G2S is often used for the construction of RVS, which combines strength and corrosion resistance. Strict adherence to this standard guarantees the durability of the structure.
SNiP 2.09.03-85
A document that describes the general requirements for the design of steel structures. It specifies the rules for calculating the load on the structure, welding features, and material quality control. This is an important standard that helps to take into account all possible loads so that the tank does not deform or collapse during operation.

Features of design in Ukraine
- Seismic activity considerations:
There are regions in Ukraine with increased seismic activity. Therefore, when designing tanks, it is necessary to take into account possible earthquakes. In such areas, tanks are designed with additional reinforcements so that the structure is resistant to soil vibrations. - Hydraulic
After construction is complete, the tank must undergo mandatory hydraulic testing. This means that the tank is filled with water to check its tightness and the reliability of the welds. This test helps to detect possible defects before operation. - Corrosion
An important part of the design and operation of tanks is corrosion protection. Steel can corrode under the influence of the external environment, especially if the tank is in aggressive conditions (salt water, chemical reagents). Therefore, various protection methods are used - from applying special coatings to using cathodic protection.
Operation of RVS
- Regular inspections and maintenance:
To ensure that your tank lasts as long as possible, regular inspections and maintenance are necessary. Welds, the condition of the anti-corrosion coating, and the overall tightness of the tank are checked. This allows for early detection and elimination of potential problems. - Welding quality control
Since welding is a key element of the RVS design, its quality is checked not only during installation, but also during operation. For this, ultrasonic tests, visual inspections and other diagnostic methods are used. - Environmental
Ukraine has strict environmental regulations. For enterprises using PVS, it is important to minimize the risks of leaks and environmental pollution. This is achieved by installing special equipment for vapor capture and conducting regular environmental inspections.
Conclusion
Compliance with standards and regulations in Ukraine is not only a legal requirement, but also a guarantee of safety and durability of vertical steel tanks. Proper design, quality materials and regular maintenance allow tanks to be used for decades, ensuring safe storage of liquids.
