Product Types: Double-layer oil tanks can be divided into three main categories based on their structural forms.

1. SF double-wall oil tank (inner layer Q235 carbon steel structure, outer layer glass fiber layer)

2. SS Double-Wall Oil Tanks (Inner and Outer Layers: Q235 Carbon Steel Structure)

3. FF Double-Layer Oil Tank (Inner Layer of Glass Fiber, Outer Layer of Glass Fiber)

Product Features: Safe and Environmentally Friendly

Double-walled storage tanks: If the inner tank leaks, gas or detection fluid under pressure within the double wall will enter the normally pressurized inner tank; the pressure or level within the double wall will change, activating the sound and light alarm. Once the stored liquid leaks into the double wall, as the outer tank remains intact, the liquid will not leak out. Therefore, the stored liquid, soil, and groundwater are all safe. If the outer tank leaks, the gas or detection fluid under pressure within the double wall will enter the soil. Similarly, the pressure or level within the double wall will change, triggering the sound and light alarm. At this point, since the inner tank is intact, the stored liquid is safe; only the gas or detection fluid enters the soil, making soil and groundwater safe as well. As the stored liquid contacting the inner tank is different from the soil and groundwater contacting the outer tank, the corrosion rates on the tank material are different, and the probability of simultaneous leakage is nearly zero. Thus, leakage of the stored liquid outside the tank can be prevented, ensuring production safety and environmental protection.
