Frequently Asked Questions
Q: What does "S/F" stand for in the fuel tank description?
S stands for Steel, referring to the inner tank that contacts the fuel. F stands for FRP (Fiberglass Reinforced Plastic), referring to the outer shell that contacts the soil for superior corrosion protection.
Q: How does the leakage monitoring system work?
A high-precision inspection device is connected to the interlayer clearance between the steel and FRP layers. Sensors monitor this space 24 hours a day and alert the operator immediately if any fuel penetrates the inner wall.
Q: Is this tank suitable for all types of fuel?
Yes, it is specifically designed for petroleum, diesel, and gasoline (including leaded petrol), as the FRP lamination does not react chemically with these fuels.
Q: What are the advantages of the FRP outer shell over steel?
Unlike steel, FRP does not undergo electrochemical corrosion when in contact with underground water or salt water, which drastically extends the tank's lifespan and protects the environment.
Q: Can the tank dimensions be customized for my specific site?
Absolutely. We can design the diameter and height according to customer requests, with volumes ranging from 1 to 100 cubic meters.
Q: How does this tank impact the installation period?
The convenient installation process of the S/F underground tank is designed to shorten the construction period, thereby decreasing the initial capital investment for the project.
