In terms of environmental protection, double-layer oil tanks are much better than single-layer ones. They have been widely promoted and are now used in all petroleum reserve enterprises and gas stations.

The advantages of double-layer oil tanks:

1.Safety features

The double-layer structure of steel-reinforced fiberglass, with a patented processing method between the inner steel shell and the outer reinforced fiberglass layer, creates a 3.5mm gap. Even if the inner shell leaks, the hazardous substances can only flow within the gap and will not spill out to pollute the environment.

The inner layer - made of 6mm - 8mm thick special steel plates, has much higher strength compared to the common single-layer tank with a thickness of only 5mm.

The outer layer - the reinforced fiberglass layer, with a thickness of more than 4mm, has strong corrosion resistance and electrical erosion resistance.

The patented technology between the double layers creates a 3.5mm gap, fundamentally eliminating potential safety hazards.

2.Environmental protection features

Ordinary single-layer steel storage tanks, buried underground all year round, are subject to erosion by groundwater vapor and electrolytic corrosion.

The double-layer structure, with a 3.5mm gap inside, and the outer FRP ensure that leaked substances will not directly seep and pollute the soil and water sources.

The outer FRP will not have electrolytic corrosion with groundwater, brine, etc.

The outer FRP will not have corrosion with gasoline, diesel, and leaded gasoline.

The leakage detector can monitor 24 hours a day to eliminate pollution risks.

The leakage detection system facilitates the detection and maintenance of the tank and protects the original ecological environment of the soil.

3.Economic features

The high safety and environmental protection performance of S/F double-layer tanks also indirectly reduces the user's cost. After using this product, there is no need to build underground oil storage rooms, and the tanks can be directly buried underground for use. The service life of S/F double-layer tanks is 3 - 5 times that of ordinary tanks and can be safely used for at least 30 years.

Installation is convenient, greatly shortening the construction period and reducing cost input.

The maintenance requirements of S/F double-layer tanks are 1/10 of those of ordinary tanks, greatly saving maintenance costs.

The utilization rate of S/F double-layer tanks is significantly higher than that of single-layer tanks, ensuring the efficient use of equipment and high cost performance.

The efficient use of S/F double-layer tanks greatly protects and saves energy, avoiding serious losses caused by energy leakage.

Due to their environmental protection, safety and economic features, double-layer oil tanks are meeting the needs of the situation and have become the preferred energy equipment for storing oil in various oil storage places.

Why must we choose high-standard double-layer tanks produced by regular manufacturers?

First, considering from the perspective of gas station owners themselves. The issue that every gas station owner cares about all the time is safety. If they purchase inferior double-layer tanks that do not meet quality standards, it will bury potential safety hazards for our gas stations.

Second, the country promotes double-layer tanks not just for the sake of changing to double-layer tanks but has important purposes and significance:

1. Leak prevention; 2. Leak detection (24-hour online detection); 3. Preparation for the recent realization of large-receipt detection networking.
