Spherical Storage Tanks: Technical Exploration from Principle to Practice

In the industrial field, spherical storage tanks occupy an important position with their unique characteristics and advantages. To deeply understand spherical storage tanks, it is necessary to start from their principles and gradually delve into various technical details in practical applications.

From the perspective of principles, the design of spherical storage tanks is based on the principle of pressure distribution in physics. Due to the shape characteristics of the sphere, the distance from each point on its surface to the center of the sphere is equal. When the tank stores liquids or gases, the internal pressure will be evenly distributed over the entire spherical surface. This uniform pressure distribution makes the spherical storage tank, under the condition of bearing the same pressure, have more uniform stress on the material compared to storage tanks of other shapes. For example, for the storage requirements of the same volume and pressure, the cylindrical storage tank will have stress concentration at the connection between the side wall and the upper and lower bottom surfaces, while the spherical storage tank does not have such a problem, which greatly improves the structural stability and safety of the storage tank.

In terms of material selection, spherical storage tanks need to use high-strength and corrosion-resistant materials. Common materials include steel, such as low-alloy high-strength steel like Q345R. These steels undergo strict quality inspection and screening and have good toughness and strength, capable of withstanding the internal pressure of the storage tank and the influence of the external environment. For the storage of some special media, such as highly corrosive chemicals, special alloy materials will be used or anti-corrosion treatment will be carried out on the inner wall of the storage tank to ensure the service life and safety of the storage tank.

The manufacturing process is a key link from the design to the practical application of spherical storage tanks. First is the processing of the plates. Through precise cutting and forming technologies, the plates are processed into curved surface shapes suitable for splicing into a sphere. Then comes the welding process. The welding quality is directly related to the sealing performance and overall strength of the storage tank. Advanced welding technologies, such as automatic submerged arc welding and gas shielded welding, are widely used in the manufacturing of spherical storage tanks. During the welding process, the welding parameters such as current, voltage, and welding speed are strictly controlled to ensure the quality of the weld. At the same time, non-destructive testing, such as ultrasonic flaw detection and radiographic inspection, is also needed to detect whether there are defects inside the weld.

During the installation process, there are also many technical points that need attention. Since the spherical storage tank is relatively large in volume, the segmented assembly method is usually adopted. During the assembly process, it is necessary to ensure the connection accuracy and sealing performance between each segment. Through precise measurement and positioning technologies, ensure that the overall shape and size of the sphere meet the design requirements. At the same time, the foundation conditions and surrounding environment of the installation site also need to be considered, and corresponding reinforcement and protection measures should be taken to ensure the stability of the storage tank during use.

In practical applications, the operation management of spherical storage tanks is also crucial. On the one hand, a complete monitoring system needs to be established to monitor parameters such as pressure, temperature, liquid level inside the storage tank, and changes in the external environment in real time. Through sensors and data acquisition systems, these data are transmitted to the monitoring center to detect abnormal situations in time and take measures. On the other hand, a strict maintenance plan should be formulated to regularly conduct inspection, cleaning, anti-corrosion treatment and other maintenance work on the storage tank to ensure that the storage tank is always in good operating condition.

In conclusion, the technical exploration of spherical storage tanks from principle to practice is a complex and rigorous process. Through in-depth understanding of the principles, careful selection of materials, strict control of the manufacturing process, accurate implementation of installation, and scientific and standardized operation management, spherical storage tanks can play their greatest role in the industrial field and provide solid guarantee for industrial production and social development.
