The reason why the oil tank is set to double

For the sake of safety, we usually make the oil tank into a double-layer oil tank, which helps prevent collisions during transportation, and there is a certain pressure of gas or detection fluid in the double-layer gap of the pressure vessel, if there is leakage , There will be an alarm device, which greatly reduces the loss of oil tank transportation.

Under normal circumstances, what we call a double-layer oil tank leak is the leakage of the outer tank. The gas or detection fluid with a certain pressure in the double-layer gap will enter the soil. In the same way, the pressure or liquid level in the double-layer gap of the oil tank will change, triggering the sound and light alarm. At this time, because the inner tank of the pressure vessel is intact, the liquid is stored safely; only gas or detection liquid enters the soil, so the soil and groundwater are also safe. There is a through gap space between the inner tank of the double-layer oil tank and the outer FRP tank; at the same time, it is equipped with a leakage detection device, which can monitor the gap space for 24 hours. Once the inner tank or the outer tank of the pressure vessel leaks, the sensor of the leakage detection device can give an alarm when the liquid level at the bottom of the gap space occurs, thereby ensuring the safe use of the oil tank.
