The full name of the double-layer oil tank is "steel reinforced glass fiber double-layer oil tank". It originated in the United States and was introduced to Japan by Tamada Industry Co., Ltd. of Japan in 1994 and implemented improvements. In the same year, the Japanese market defined the product "steel-reinforced glass fiber double-layer oil tank", formulated relevant standards, and gradually promoted its use. According to statistics, the current application of double-layer oil tanks in gas stations in developed countries such as Japan, Europe and the United States has rapidly increased from 7.1 in 1985 to 98 at the end of 2009. Zhongyue FRP Co., Ltd. has accelerated the popularity of SF double-layer tanks in the Chinese market.
Double-layer oil tanks can be promoted and used in the market so quickly, mainly because they have unparalleled safety, environmental protection and economic performance compared with ordinary single-layer steel oil tanks. A comprehensive overview is as follows:
1. Double-layer structure made of steel reinforced glass fiber. A patented processing method-resin film coating method is used between the inner steel shell and the outer reinforced glass fiber layer to create a gap between the inner and outer layers. With a 0.1mm gap, even if the inner shell leaks, it can ensure that the dangerous substances contained only flow in the gap and will not immediately overflow and pollute the environment. It is efficient and environmentally friendly. At the same time, the oil tank is equipped with an advanced leak detector made in Japan. Once an internal leak occurs, the sensor can sense the leakage flow and generate a buzzer alarm to ensure that users stop using it as soon as possible and repair it in time. It fundamentally cuts off the possibility of various accidents caused by hazardous materials leaving the outside world.
2. The fiberglass shell can fully protect the internal steel shell from external corrosion. Ordinary single-layer steel oil tanks are buried underground all year round and are corroded by underground water vapor and electrolytic corrosion. Therefore, their service life is very short. They only have a service life of 5 to 10 years depending on the environment. Moreover, oil tanks are easily damaged after corrosion. crack, causing the contents to leak; the fiberglass shell on the outside of the double-layer oil tank is made of special resin and reinforced fiberglass jet yarn in one injection molding, and has undergone multiple tests of pressure and decompression to ensure that the outside is completely sealed during use. Water vapor will not enter the interior and corrode. At the same time, glass fiber is an insulating object, so it will not cause electrolytic corrosion. This ensures that the double-layer oil tank can be used for at least 25 years in normal environments.
3. The high safety and environmental protection performance of the double-layer oil tank also indirectly reduces the user's cost of use. After using this product, there is no need to build an underground oil storage room, and the oil tank can be directly buried underground for use. . Generally, ordinary single-layer steel oil tanks need to be repaired and inspected every year, which increases maintenance time and cost. However, double-layer oil tanks do not require inspection of the internal steel shell at all, and the surface inspection of the fiberglass outer shell is only performed once every 3 years. , and even if there is an abnormality, the same material can be used to repair a small area, saving time and effort. Therefore, this product greatly reduces the comprehensive cost of use for customers.
