The reason for fast promotion and application in the market of the double lagers oil tank is from its sole advantages such as safety,environment protection and low cost comparison with sing layer steel oil tank.lt is composed of steel inner tank and fiberglass reinforced outer tank made by special equipment with patent.The tank possess a uniform interlayer space which connected with leakage detector,can monitor the leakage at any time.

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%)

Features as below:
1,Safety
1.1 lnner layer: Adopting premium Q235-B steel plate, it is thicker than the common single layer steel tank (5mm thick) and the strength is improved sharply.
1.2.Outer layer: The thickness of FRP lamination is more than 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, Environment protection
2.1.The outer FRP lamination can prevent the contamination of the soil and water source from the leakage.
2.2. The outer FRP lamination can't produce electrochemical reaction with underground water or salt water.
2.3. The outer FRP lamination can't produce chemical reaction with gasoline,diesel,and gasoline including lead.
2.4. The installation of the leakage detector is convenient; the sensor is entered inside the monitoring pipe is OK.The output will be connected with monitor device and power source,and then can keep the monitoring 24hours.
2 5.It is very convenient to check and maintain the leakage monitoring system,and protect the soil and water ecological environment.
3.Economy
3.1.The service life of the S/F double layers oil 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 cost input. 
3.2.Remote monitor system is convenient to the daily and periodic inspection and test; the digital control can release the complicated manual operation.
