The features and advantages of SS double-layer steel horizontal storage tanks are as follows:

In terms of structural design and strength

•Double-layer steel plate structure: The inner layer is made of 8-10mm thick Q235-B steel plate, and the outer layer is made of 6-10mm thick Q235-B steel plate. Compared with ordinary single-layer oil tanks, the strength is significantly improved, which can effectively withstand internal and external pressures.

•Uniform interlayer space: A through gap between the steel inner tank and the steel outer tank forms a uniform interlayer space, which can be used to install leakage detection devices and also play a certain buffering role.

•Stable overall structure: Equipped with 300 heavy-duty I-beam integral brackets and outer box integral isolation devices, the structural stability is strengthened to adapt to different installation environments.

In terms of safety performance

•Leakage monitoring and alarm: The storage tank is equipped with a leakage detector, which can carry out 24-hour real-time monitoring of the interlayer space. Once the inner or outer tank leaks, the detection device can monitor the liquid level change at the bottom of the gap space and issue an alarm to timely remind staff to take measures.

•Prevention of leakage pollution: Even if the inner tank leaks, the stored liquid will not directly leak into the soil and groundwater due to the protection of the outer tank, effectively preventing environmental pollution caused by liquid leakage and protecting the safety of soil and groundwater.

In terms of corrosion resistance

•Good corrosion resistance of the material itself: Q235-B steel plate has certain corrosion resistance and can resist the erosion of stored liquids and the external environment to a certain extent. At the same time, the tank body can be subjected to anti-corrosion treatment, such as coating anti-corrosion coatings, to further improve corrosion resistance.

•Double-layer structure reduces corrosion risk: The double-layer structure makes the inner and outer tanks contact different media respectively (the inner tank contacts the stored liquid, and the outer tank contacts the soil and groundwater). The corrosion rates of different media on the tank material are different, and the probability of simultaneous leakage of the inner and outer tanks at the same time is extremely low, reducing the overall risk of corrosion and leakage.

In terms of construction and maintenance

•Convenient installation: The horizontal structure is easier to transport and install than vertical storage tanks, has relatively low requirements for the installation site, and can complete the installation work in a short time, reducing construction time and costs.

•Low maintenance cost: Compared with some other materials or structures of storage tanks, the maintenance of SS double-layer steel horizontal storage tanks is relatively simple, does not require special maintenance equipment and technology, and the double-layer structure is convenient for inspection and maintenance, reducing long-term maintenance costs.
