S/F double wall underground fuel tank is more safety, environmental protection and economically, 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, it is corrosion resist, isolation etc, S/F dual-layer oil storage tank manufactured with professional equipments, and there is interlay clearance between internal steel layer and external FRP layer,is connected with the interlayer clearance, monitoring the leakage all the time.

1) Fiberglass reinforced plastics jacketed steel underground fuel tank volume: 1-100 cubic meters
2) Dimension: we could design diameter and height as per customers' request
3) Material: Fiberglass/Steel
4) Diesel fuel tank shell thickness: 6-10 mm
5) Pressure (MPa): Atmospheric pressure Middle pressure (According to the Chinese Design standard)
6) Function: Oil Storage tank, fuel storage tank, diesel storage tanks, gasoline tank liters, gasline tank

Safety
1.Internal layer- made by Q235 steel plate with 6-8mm thickness.
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.
3.The interlayer space is formed by sole technology, the leakage detector keeps 24 hours monitoring, to avoid the hidden trouble absolutely.Environmental protection
1.The external FRP layer can prevent the contamination of the soil and water source from the leakage.
2.The external FRP layer will not generate electrochemical reaction with underground water or salt water.
3.The external FRP lamination can't produce chemical reaction with petrol, diesel and petrol including lead.
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 24 hours.
5.It is very convenient to check and maintain the leakage monitoring system, and protect the soil and water ecological environment.
