In order to facilitate the transportation of oil during the operation of the F-style oil can, a heater is arranged in the tank for storing heavy oil and crude oil, and the outside of the tank wall is also insulated. According to the requirements of production, maintenance and safety, the oil tank is provided with: 1 oil hole (also used as sampling hole); 2 oil tank for storing gasoline, kerosene, light diesel oil, crude oil and aromatics, and a breathing valve is required; 3 storage fuel Oil tanks for heavy oils such as oil, feedstock oil, heavy diesel oil and wax oil are required to have ventilation holes; 4 holes, light transmission holes and cleaning holes (the latter is only provided in heavy oil tanks).
Inspection observation of F type oil tank
After the F-type oil tank is built, it must be filled with water for inspection. The main purpose of the F-type oil tank is to verify the reliability of the tank structure when it is used. Check for leaks (including welds and non-ferrous steel tanks). Crack in the metal oil tank); pre-pressed foundation. For the weak foundation, the water filling rate should be strictly controlled so that the settlement of the tank is not too fast. At the same time, attention should be paid to the change of the surface soil around the tank to avoid the shear failure of the foundation. The tank tank shall be continuously subjected to settlement observation work from the foundation construction to the time after the production.
For the floating roof tank, a floating roof lifting test is also required. When filling and discharging water, it is important to check the smoothness of the floating roof, the tightness of the seal and the guiding part, and the leakage of the central drain.
