Structural features of oil storage tank

Oil storage tank has the following structural features:
①Sturdy tank body
Usually made of metal materials, such as carbon steel or stainless steel, it has high strength and rigidity, can withstand the pressure of oil products and the influence of the external environment, and ensure long-term and stable storage of oil products. The thickness of the tank body is designed according to the storage capacity and pressure requirements to ensure the safety of the structure.
②Various tank tops
There are many types of tank tops, the most common ones are fixed tops and floating tops. The fixed top has a simple structure and can effectively prevent rainwater, dust, etc. from entering the tank, but the oil volatilization loss is large. The floating top is divided into an external floating top and an internal floating top. The floating top rises and falls with the liquid level in the tank, which can greatly reduce the contact area between the oil and the air, reduce the volatilization loss, and also reduce safety hazards such as fire.
③Good sealing of the tank bottom
The tank bottom is in direct contact with the ground and needs to have good sealing and corrosion resistance. Generally, an anti-corrosion coating is laid on the bottom of the tank or special anti-corrosion materials are used to prevent oil leakage and groundwater erosion of the tank bottom. At the same time, the structural design of the tank bottom must also take into account the sedimentation and drainage of the oil products to ensure the quality of the oil products in the tank.
④Complete auxiliary facilities
Equipped with various auxiliary facilities, such as oil inlet and outlet pipelines, valves, liquid level gauges, thermometers, pressure gauges, etc. These facilities are used to control the inlet and outlet of oil products, monitor the status of oil products in the tank, and ensure the safe operation of the oil storage tank. In addition, there may be safety devices such as breathing valves and flame arresters to prevent abnormal pressure in the tank and fire and explosion accidents.
