SF double wall diesel fuel storage tank 

SF dual-layer oil storage tank is more safe, environmental and economical. 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. 

Application of SF double wall oil storage tank 

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%).

Structure of SF Dual-Layer Storage Tank

a. The inner layer is made of stainless steel;

b. the out layer is made of FRP; 

c. there is interlay clearance between internal steel layer and external
FRP layer;

d. high-precision monitoring device is connected with the interlayer clearance,
monitoring the leakage all the time. 

Monitoring System Structure

Feature and Advantage of SF Dual Layer Oil Storage Tank

1. Safety
1.1 Internal layer- made by Q235 steel plate with 6-8mm thickness.
1.2 External layer-fiberglass reinforced layer, it’s thickness is ≥4mm, It possess
excellent property such as compression resistant, shock resistant, corrosion
resistant and electrochemical corrosion resistant.
1.3 The interlayer space is formed by sole technology, the leakage detector keeps 24
hours monitoring, to avoid the hidden trouble absolutely.
2. Environmental protection
2.1 The external FRP layer can prevent the contamination of the soil and water
source from the leakage.
2.2 The external FRP layer will not generate electrochemical reaction with
underground water or salt water.
2.3 The external FRP lamination can't produce chemical reaction with gasoline,
diesel and gasoline including lead.
2.4 The installation of the leakage detector is convenient, just put the sensor into
monitoring pipe. The output will be connected with monitor device and power
source, and then can keep the monitoring for 24hours.
2.5 It is very convenient to check and maintain the leakage monitoring system, and
protect the soil and water ecological environment.
3. Economic practically
3.1.The service life of the S/F dual-layer oil storage tank is 3~5 times of the
common single layer oil tank, at least 30 years. The convenient installation can
shorten the construction period and decrease the investment.

3.2 Remote monitor system is convenient to the daily and periodic inspection a
nd test, the digital control can release the complicated manual operation.
