Advantages of underground double layer oil tank

At present, the following problems commonly exist in steel tanks:
1. traditional anti-corrosion measures make its service life shorter, usually only 7-10 years
2. after the single-layer oil tank is buried, it is impossible to know whether there is any leakage and hidden danger
3. because the service life of single-layer oil tank is short, resulting in repeated investment
 
The new type of buried SF double-layer oil tank in gas station produced by oil tank manufacturer has the following characteristics:
 
1. safety features:
The steel reinforced glass fiber double-layer structure of the underground double-layer oil tank adopts the patented processing method between the inner steel shell and the outer reinforced glass fiber layer to create a 3.5mm gap between the inner and outer layers. Even if the inner shell leaks, it can ensure that the contained dangerous substances only flow in the gap and will not overflow the outside to pollute the environment.
 
 The inner layer is made of 6mm-8mm thick special steel plate, which is similar to the general steel plate Compared with the single-layer tank with a thickness of only 5mm, the strength of the tank is greatly improved; the outer layer - reinforced glass fiber layer, with a thickness of more than 4mm, has strong corrosion resistance and electrical corrosion resistance; the patented process technology is adopted between the two layers to make the gap reach 3.5mm, so as to eliminate the existence of potential safety hazards from the root;
 
2. environmental protection characteristics
Ordinary single-layer steel storage tank will be eroded and electrolytic corroded by underground water and gas because it is buried in the ground all the year round; underground double-layer oil tank is a double-layer structure with 3.5mm gap inside, and the outer FRP ensures that the leakage will not directly leak and pollute the soil and water source. The outer FRP will not produce electrolytic corrosion with underground water, salt water, etc.; the outer FRP will not produce electrolytic corrosion with gasoline, diesel, leaded gasoline, etc Corrosion phenomenon; underground double oil tank leakage detector can monitor the whole process 24 hours to eliminate potential pollution; leakage detection system is convenient for detection and maintenance of double oil tank, and protects the original ecological environment of soil. 3. economic characteristics
The high safety and environmental protection performance of SF double-layer tank also indirectly reduces the user's use cost. After using the product, the underground oil storage room can be avoided, and the storage tank can be directly buried in the underground for use. The service life of SF double-layer tank is 3-5 times of that of ordinary storage tank, and the safe use can be guaranteed for at least 30 years.
 
4. convenient installation,
Greatly shorten the construction period and reduce the cost investment. The maintenance demand of SF double-layer oil tank is 1 / 10 of that of ordinary tank, which greatly saves the maintenance input cost; the utilization rate of SF double-layer tank is greatly improved compared with that of single-layer tank, which ensures the efficient use of equipment and high cost performance of products; the efficient use of SF double-layer tank greatly protects and saves energy, and avoids the serious loss caused by energy leakage.
