The reason for fast promotion and application in the market of the double lagers oil tank is from its sole advantages such as safety, environment protection and low cost comparison with sing layer steel oil tank.lt is composed of steel inner tank and fiberglass reinforced outer tank made by special equipment with patent.The tank possess a uniform interlayer space which connected with leakage detector,can monitor the leakage at any time. operation manhole well cover manhole hook a burglar alarm leak detecting hole vapor oil sensor
The tank can store the following media such as gasoline, diesel, and kerosene, also can store solid or liquid,alcohol and concentrated sulfuric acid (98%) frp cuter shell vacuum layer lnner steel shell clapboard signal cable
Features as below: double reinforcad plate for leak detecting alarming liquid level 8mm leaked oil
1,Safety
1.1 lnner layer: Adopting premium Q235-B steel plate, it is thicker than the common single layer steel tank (5mm thick) and the strength is improved sharply.
1.2.Outer layer: The thickness of FRP lamination is more than 4mm,It possess excellent property such as compression resistant,shock resistant,corrosion resistant and electrochemical corrosion resistant.
1.3.The interlayer space is formed by sole technology;the leakage detector keeps 24 hours monitoring, to avoid the hidden trouble absolutely.
2,Environment protection
2.1.The outer FRP lamination can prevent the contamination of the soil and water source from the leakage.
2.2. The outer FRP lamination can't produce electrochemical reaction with underground water or salt water.
2.3. The outer FRP lamination can't produce chemical reaction with gasoline,diesel,and gasoline including lead.
2.4. The installation of the leakage detector is convenient; the sensor is entered inside the monitoring pipe is OK.The output will be connected with monitor device and power source,and then can keep the monitoring
24hours. Double Layer Lpg Tank /big Volume Oil Storage Tank For Sale In High Quality Most Popular Made In China
2 5.It is very convenient to check and maintain the leakage monitoring system,and protect the soil and water ecological environment.
3.Economy
3.1.The service life of the S/F double layers oil tank is 3~5 times of the common single layer oil tank,at least 30 years.The convenient installation can shorten the construction period and decrease the cost input.
3.2.Remote monitor system is convenient to the daily and periodic inspection and test; the digital control can release the complicated manual operation. High Quality Double Layer Lpg Tank,Gas Storage Tank,Big Volume Oil Storage Tank


Production line


The tank has a standard capacity of 20,000L, but it can also be customized to suit your specific requirements.
The tank is made from advanced FRP (Fiber Reinforced Plastic) material for the outer layer and premium Q235-B steel for the inner layer, providing excellent durability and resistance to corrosion.
The double layer design enhances security by preventing leaks and offering additional protection against environmental factors, ensuring safe storage of fuel oil.
This tank is suitable for storing various fuels including gasoline, diesel, kerosene, liquid oxygen (LOX), liquid nitrogen (LIN), liquid argon (LAR), liquid carbon dioxide (LCO2), and liquefied natural gas (LNG).
The dimensions of the tank are 1200mm x 1000mm x 1150mm, making it compact yet spacious enough for large-scale fuel storage.
