Product Launch: Redefining Underground Fuel Safety
Environmental safety is no longer optional; it is an absolute necessity in modern fuel management. Zhongneng Huajian is proud to launch our upgraded SF Double-walled Fuel Tank series, specifically engineered for gas stations and industrial fuel depots. The "SF" structure (Steel inner tank, Fiberglass reinforced plastic outer tank) provides a dual-layer barrier against both internal corrosion and external soil degradation, completely eliminating the environmental risks associated with traditional single-wall tanks.

Key Technical Advantages of the SF Series
Unlike single-wall alternatives, our double-walled tanks feature a dedicated interstitial space that allows for continuous leak detection monitoring. This ensures any potential breach is detected long before it can harm surrounding soil or groundwater. The composite outer shell is 100% immune to underground water and soil corrosion. Installation is highly efficient; pre-fabricated components significantly reduce on-site construction time for underground fuel storage systems, saving both time and labor costs. Available in volumes from 10,000L to 50,000L, these tanks are fully customizable.

Frequently Asked Questions (FAQ) for Operators

Q: How does the leak detection system in SF tanks work?

A: The interstitial space between the steel inner tank and fiberglass outer shell can be equipped with vacuum, pressure, or liquid sensors, providing 24/7 continuous monitoring and automated alerts.

Q: Are SF tanks compliant with strict environmental regulations?

A: Yes. The 100% leak-proof design and continuous monitoring capabilities make our SF double-walled fuel tanks fully compliant with the most stringent global environmental protection mandates.

Q: What is the typical lifespan of an SF underground tank?

A: Due to the complete immunity of the outer fiberglass shell to electrochemical soil corrosion, SF tanks typically offer a lifespan exceeding 30 years with proper maintenance.
