Vertical steel tanks (VSTs) have long been the main choice for storing liquids at industrial facilities. In Ukraine, they are actively used in the oil, gas, chemical and other industries. In this article, we will consider why VSTs are so popular, what advantages they have compared to other types of tanks and what you should pay attention to when using them.
Advantages of RVS
Vertical steel tanks (VSTs) have many advantages that make them the best choice for storing liquids in industrial facilities. Let's consider the key advantages of these tanks:
Strength and durability
Steel is one of the strongest materials for tanks. RVS made of high-quality steel can last for decades if properly operated. It is important that the steel meets Ukrainian standards, such as DSTU 2651:2010, as this guarantees the tank's resistance to mechanical damage and aggressive external factors.
Cost-effectiveness in the long term
Although building a steel tank may seem expensive at first, its durability and ease of maintenance make it worth the cost. Unlike other materials, steel is repairable, and in the event of damage, the defect can be repaired without having to replace the entire tank.
Corrosion protection
Modern steel tanks are protected from corrosion by special coatings. This is especially important when storing aggressive substances, such as petroleum products or chemical reagents. For example, epoxy coatings are often used for protection, which have excellent resistance to chemical attack.
Versatility of application
PBCs can be adapted to different types of liquids, which makes them versatile. Depending on the purpose of use, the tanks can be additionally equipped with various temperature, pressure and liquid level control systems.
Environmental safety
When operated correctly, vertical tanks virtually eliminate leaks and emissions into the environment. This is especially important for businesses that strive to meet strict environmental standards. Regular inspections and maintenance help prevent potential accidents.
Comparison with other tank types
Let's take a look at how vertical steel tanks (VSTs) compare to other tank types:
- Plastic tanks :
Plastic is often used to store some chemicals, but it is less durable and is subject to degradation by sunlight and temperature fluctuations. Unlike steel tanks, plastic tanks are less durable and require more frequent replacement. - Concrete tanks :
Concrete tanks are resistant to mechanical stress, but they are not suitable for storing liquids that are aggressive to the material. Steel tanks are superior in terms of reliability and speed of installation, as the construction of concrete tanks requires more time and investment. - Composite tanks :
PVA tanks are superior to composite tanks in terms of strength, durability and temperature resistance. Steel tanks can withstand high mechanical loads, last for decades and are easier to repair, making them more economical in the long run. While composite tanks wear out faster and are less resistant to extreme temperatures. - Aluminum tanks :
RVS also outperform aluminum tanks in terms of strength and durability. Steel tanks can withstand higher mechanical loads and last longer, especially in aggressive environments. Aluminum tanks are lighter and have good corrosion resistance, but they are less durable and can deform under strong mechanical stress.
Practical examples
Let's consider an example of an oil storage facility at one of the plants in Ukraine. A vertical steel tank with a volume of 2000 m³ was chosen for this facility. Thanks to the use of a special anti-corrosion coating and regular inspections, the tank has been successfully operated for more than 15 years without the need for major repairs. This proves the economic benefit and reliability of RVS for long-term storage of liquids.
Conclusion
Vertical steel tanks are a time-tested solution for storing liquids. Their strength, durability and versatility make them indispensable in industrial processes. The right choice of materials, compliance with standards and regular maintenance allow the operation of the PVS for many years without loss of quality and safety.
