Now, an increasing number of gas stations are opting for double-walled fuel tanks due to their enhanced safety features. Why are double-walled fuel tanks considered safer? Hunan Double-Wall Tank Co., Ltd. and Guanglei Metal will provide you with a detailed introduction!

In the event of a leak in the inner tank of a double-walled oil tank, the pressurized gas or detection fluid within the double space will enter the normal-pressure inner tank; the pressure or liquid level within the double space will change, triggering an audible and visual alarm. After the stored fluid leaks into the double space, as the outer tank remains intact, the stored fluid will not leak out. Therefore, the stored fluid, soil, and groundwater are all safe.

Leak Detection Device

If the outer container leaks, gas or detection fluid under pressure within the double layer gap will enter the soil. Similarly, changes in pressure or liquid level within the double layer gap will activate the sound and light alarm. At this point, since the inner container remains intact, the stored fluid is safe; only the gas or detection fluid enters the soil, making both the soil and groundwater safe.

Due to the storage liquid contacting the inner tank and the soil, groundwater contacting the outer tank being different media, the rate of corrosion of the tank material varies, and the probability of leakage occurring simultaneously is nearly zero. Therefore, leakage of the stored liquid outside the tank can be prevented, ensuring production safety and environmental protection.

Here's an explanation of the safety features of double-wall tanks. For those interested in learning more about double-wall tanks in Hunan, welcome to consult Guanglei Metal!
