Frequently Asked Questions
Q: What is the primary difference between S/F and single-wall tanks?
S/F tanks feature a dual-layer design: a steel inner layer (S) for fuel containment and an FRP outer layer (F) for corrosion protection, whereas single-wall tanks lack this secondary protective barrier and monitoring space.
Q: Which fuels are compatible with S/F underground tanks?
These tanks are designed for a wide range of fuels, including diesel, gasoline, and petroleum, as the inner steel layer is optimized for oil contact and the outer FRP layer prevents external chemical reactions.
Q: How does the leakage monitoring system work?
A high-precision sensor is placed in the interlayer clearance between the steel and FRP layers. If the inner tank leaks, the sensor detects the fluid in the gap and triggers an immediate alert through the monitoring device.
Q: Is FRP really effective against underground corrosion?
Yes, Fiberglass Reinforced Plastic (FRP) is naturally resistant to electrochemical corrosion, meaning it will not react with salt water or groundwater, effectively shielding the inner steel tank from soil-based decay.
Q: Can the tank dimensions be customized for small sites?
Absolutely. We can design the diameter and height based on your specific customer requests and site constraints, with volumes available from 1 to 100 cubic meters.
Q: What certifications do these fuel tanks hold?
Our manufacturing processes are ISO9001 and ISO14001 certified, ensuring that every tank meets international quality and environmental management standards.
