1. Structural Features
The Self-Bundled Tank features a double-walled design. The inner tank stores the medium, while the outer tank serves not only as a protective layer but also as a containment chamber, forming a natural leak-proof barrier. No additional concrete dike is needed between the inner and outer tanks, resulting in a compact overall structure. Integrated molding enhances structural stability, adapting to various site conditions, and is particularly suitable for space-constrained areas.
2. Core Functional Advantages
The most prominent advantage of this type of tank is its leak-proof safety. The outer tank can contain all media that might leak from the inner tank, effectively preventing contamination of soil, groundwater, and the surrounding environment. It also boasts a small footprint, significantly saving site resources and reducing initial infrastructure investment compared to traditional tanks with dikes. Furthermore, its installation process is simple, requiring no complex foundation engineering, allowing for rapid deployment and commissioning.
3. Applicable Applications
Widely used in petrochemical, energy storage, and chemical raw material storage fields, it is particularly suitable for storing various flammable, explosive, toxic, and highly corrosive liquid media. This design is particularly suitable for use in remote energy supply stations, small chemical industrial parks, and temporary storage sites, meeting both the safety requirements of media storage and adapting to the needs of different environments.
4. Safety Protection Design
In addition to the basic protection of double-walled tanks, a comprehensive monitoring system is typically installed to monitor pressure, liquid level, and other data between the inner and outer tanks in real time, promptly detecting potential leakage risks. The tank body is made of high-quality, corrosion-resistant, and anti-aging materials, enhancing long-term reliability. Combined with anti-static and lightning protection designs, it comprehensively ensures safety during storage and use, complying with various industry safety standards and specifications.
