SF double walled oil storage tank is made of 2 layers. S means steel for inner tank which contacts with oil fuel, like petroleum, diesel etc; F means FRP for outer shell which contacts with soil. 

S / F dual-layer oil storage tank is currently it is more and more popular and has been applied to many fields such as hospital helicopterfuel filling system, airplane fuel filling system,vessel fuel filling system, construction of outdoor tanks storage,transportation device of different liquid,chemical device,petroleum device, filling station,selling and repairing of measurement device, selling and repairing of vehicle washing machine, oil piping and storage device of other dangerous goods.

The tank can store the following media such as gasoline, diesel, and kerosene, also can store solid or liquid,alcohol and concentrated sulfuric acid (98%).

Monitoring System of Double Walled Fuel Tank (fuel tank alarm)

1) The inner layer - made of 6m thick Q235-B steel plate, is much stronger than a single tank with a thickness of only 5mm. Overhaul extrinsic - strengthens glass fibers from, thickness up to 2. Above 5m, good shock resistance. Strong corrosion and electric corrosion resistance:
The specific process technology is used between the two layers to achieve 0. 1m gap, eliminate hidden trouble from the root.
The advanced leak detector monitors the system in real time for 24 hours to eliminate the security risks caused by the leakage

2) Environmental protection
It's a two-layer structure. It has a 0. 1mm gap, the outer FRP ensures that the leakage will not directly leak contaminated soil and water.
The outer FRP does not cause electrolytic corrosion with groundwater, saline, etc.
The outer FRP will not corrode with gasoline, diesel oil and leaded gasoline.
The leak detector can monitor the whole process for 24 hours to eliminate the potential pollution
The monitor leakage detection system facilitates detection and maintenance and protects the soil and water environment.
The effective protection of the environment avoids the high cost of environmental protection economy.

3) Economy
The service life of the double-deck tank is 5-10 times that of the ordinary tank, which can guarantee at least 30 years of safe use.
Convenient installation, greatly shorten the construction period, reduce the cost of investment.

The monitor system performs routine and periodic inspection, digital control, and eliminates manual complexity.
S/F The protection requirement of double-deck oil tank is generally related to 1/10, which greatly saves the maintenance cost.
S/F Compared with ordinary tank, the use of double-deck oil tank is improved greatly, which ensures the efficient use of equipment and high cost performance.
S/F The double-deck oil tank has high economic efficiency, high environmental protection performance, and can effectively protect energy, avoiding the serious harm and loss caused by energy leakage.
