Underground SF oil tank in China
The outer glass fiber reinforced plastic of the SF double-layer water tank ensures that the leakage will not directly leak and pollute the soil and water sources, and protect the ecological environment of water and soil. At the same time, the FRP shell can fully protect the inner steel shell from external corrosion. Ordinary single-layer oil tanks are buried in the ground all the year round and electrolytically corroded by the erosion of underground water vapor, so the service life is very short. According to the environment, the service life is only about 10 years, and the oil tank is easily damaged and cracked after corrosion, resulting in Leakage of internal items; while the glass fiber shell outside the double-layer tank is spray-molded by a special process to ensure a complete seal on the outside, and no water vapor will enter the inside to cause erosion during use. Electrolytic corrosion will occur, which can ensure that the double-layer oil tank can be used safely for at least 30 years under normal circumstances.
