What is the function of double-layer oil tank double insurance

The double-layer oil tank has two layers of tank walls, so it has great advantages in many aspects, especially in terms of preventing leakage. Not only that, but also the manufacturing requirements of foreign standards On-line monitoring and manual inspection of the gap between the two layers of the pressure vessel's tank wall, whether the leakage of the inner tank or the outer tank, can be found in the through gap, which can effectively prevent the leakage of oil from entering The environment pollutes soil and groundwater.

The inner steel and outer glass fiber reinforced plastic double-layer oil tank is a single-layer steel oil tank with a layer of glass fiber reinforced plastic (ie, glass fiber reinforced plastic) impermeable jacket to form a double-layer oil tank. In addition to the common characteristics of double-layer oil tanks, this pressure vessel is also far superior to steel oil tanks in terms of soil and chemical corrosion resistance of its outer glass fiber reinforced plastic tank, so its service life is longer than that of direct contact with the soil. The steel tank needs to be long.

Leak detection is achieved by detecting the change in the volume of the oil in the double-layer oil tank. This method is not easy to find small leaks. Dye is added to the water, and the leak is detected by a hydraulic test. In addition, you can listen to the sound on the tank wall or install an acoustic wave sensor on the tank wall, set up an observation well to monitor the pressure vessel tank area, and use a dipstick to detect the tank liquid level for leak detection. Materials must be inspected and stored in the warehouse. The double-layer oil tank on the ground is mainly inspected by ultrasonic, which is more efficient. Perform a water filling test on the newly built or repaired oil tank, check whether the wall of the double-layer oil tank is tight, and perform visual inspection of the tank wall and weld. Double-layer oil tank has double safety function, double-layer glass fiber reinforced plastic oil tank, the inner and outer layers of the pressure vessel are glass fiber reinforced plastic tanks, which are superior to those with metal tanks in terms of resistance to internal and external corrosion Oil tank.
