S/F double wall oil storage tank consist of inner carbon steel tank which contact with oil and outer

FRP shell which contact with soil, and manufactured by professional equipments. Between inner

steel tank and outer FRP shell, there is a uniform interlayer space, high-level leakage inspection

device is connected with the interlayer space, monitoring the leakage of the tank all the time.

Advantages of SF double layer underground diesel oil storage tank

First, steel reinforcement glass fiber system of double layer structure, the internal steel shell with
external reinforcement glass fiber layer between the patent processing method - resin film coating
can produce 0.1 mm gap between the inside and outside layers, even if the inner leak, also can

ensure the danger only flow in the gap, not immediately overflow outside pollution

environment, efficient environmental protection. At the same time, the tank is

equipped with Japanese senior leak detector,once the leak inside, find leakage flow

to flow produce buzzer alarm, ensure that users in the first place to stop using and

repairing in time. Radically cut off the possibility of danger logistics various outside

after the accident.

Second, glass fiber shell can fully protect the internal corrosion of steel shell was not influenced by
the outside world. Common monolayer steel tank for perennial buried by underground water corrosion

and electrochemical corrosion, so the service life is very short, only 5 ~ 10 years according to the
environment of use fixed number of year, and after the oil tank corrosion susceptible to damage, leads  

to the leakage of content items; And double shell of tank external glass fiber is with a special resin and

glass fiber yarn jet injection molding, and after pressure relief multiple testing, to ensure that

the external completely sealed, in use process won't by moisture into the internal erosion, glass fiber
is insulation object at the same time, also won't produce electrochemical corrosion, so that ensure the
two-layer tank in environment usually can use more than 25 years at least.

Three, double tank of high security, high environmental performance also indirectly reduce the use of
user cost, after using the product can do not need to build underground oil storage, oil tank can be
used directly buried underground. Between common monolayer steel tank every year, the need for
maintenance and testing, increases the maintenance time and costs, and the double tank internal steel

shell don't need to test, only 3 years one surface of the glass fiber surface detection, and even if
there are abnormal phenomenon, also can use the same material for repairing small area, save time

andeffort. So the product is greatly reduce the comprehensive cost of the customer's use.
