Composite Double Layer Structure Design FRP Oil Storage Tank

Product Description:

Sign of The Times：

Since the world's first gas station was born in the United States in the early 20th century, the new term "gas station" has been recorded in history. With the rapid development of the automobile industry, gas stations have sprung up like mushrooms. However, with the continuous growth of gas stations, in addition to the rapid development of the automobile industry, there are increasingly strict environmental protection requirements. Environmental pollution caused by oil leakage is an urgent problem to be solved by all countries.

At the beginning of the 1960s, Germany pioneered the double-layer tank for storing oil products, and this double-layer tank is made of steel inside and outside, known as SS double-layer

In the early 1980s, the American Steel Tank Association launched the SF double tank, which is lined with steel structure, and the outer tank wall is made of FRP and glass fiber reinforced plastic, which effectively resist the erosion from groundwater, microorganisms and soil environment in the buried environment

Subsequently, at the end of 1980s, the world's first FF double-layer tank made of BOTH inner and outer FRP materials came out in Los Angeles, USA. This dual-layer FRP storage tank solves the problems existing in previous oil tanks with metal structure, and is well adapted to the corrosion problems caused by the development of biofuels and alternative fuels in recent years. Therefore, it has been widely recognized and supported by laws and regulations, as well as third-party certification organizations such as UL

With the development of national economy and the continuous enhancement of people's awareness of environmental protection, laws and regulations related to environmental protection in China are gradually improved. The topic of environmental protection has attracted more and more attention, and the environmental protection of air, water and soil has become the focus of society. Through the "two sessions" during many environmental proposals, let us the whole society is aware of the seriousness of the problem, China has completed the "air ten" revision and "water ten" official release, and the "soil ten" is also coming out.

In the eighth article of the "Water Rule", it is required in the prevention and control of groundwater pollution that all underground oil tanks of gas stations should be upgraded to double tanks or anti-seepage ponds should be set up before the end of 2017.

Double wall FRP oil storage tank features:

As fuel and chemical containing liquids stored in underground steel tanks around the world have become more and more erosive over the past few decades, a large number of markets are moving towards using FRP tanks in addition to coating the inner surfaces of existing steel tanks. Because the permeability and compressive strength, FRP tanks from single-walled incline to double wall, both inside and outside double using enhanced glass fiber materials, has a long service life, corrosion resistance, prevent conductive, light weight, free maintenance, as well as good seismic performance, production process mainly has the short cut fiber injection method, the centrifugal casting method, winding molding process, such as double even the more than 30 years of glass fiber reinforced plastic production Product design and manufacturing experience, quality assurance let you rest assured.

Comparison table of characteristics of various double - wall storage tanks

LZFRP production of FRP double way oil tank adopts double structure design, in the interlayer between the inner and outer wall can be installed within 24 hours of continuous monitoring system, both inside and outside wall leakage, mezzanine can be automatic induction and alarm, instant repair, put an end to the oil cause pollution to soil and underground water, in line with international environmental requirements:

1.Double - wall tank is a continuous leakage monitoring system when damaged.

2.If the inner wall of the double-wall tank is damaged or leaked, the detected liquid level in the interlayer between the inner and outer walls will drop.

3.If the outer wall of the double-wall tank is damaged or leaked, the detected liquid level in the interlayer between the inner and outer walls will also decrease.

4.If the groundwater level is higher than the detected liquid level in the sandwich and the outer wall is damaged or leaked, the detected liquid level in the sandwich will rise.
