API Std 650 carbon steel tank backing
Under the same sealing effect, the internal floating roof tank of API 650 oil storage tank can further reduce the evaporation loss compared with the API Std 650 carbon steel tank External floating roof tank. This is due to the shielding of the fixed roof and the gas layer between the fixed roof and the internal floating plate, which has more significant heat insulation effect than the double disc floating roof of the API Std 650 carbon steel tank external floating roof tank.
Testing the Outer Tank: While the test pressure is being held, all welded seams and connections in the outer shell and roof shall be thoroughly inspected with a solution film unless they were previously checked with a vacuum box. The API Std 650 carbon steel tank air pressure shall be released. Pressure relief and vacuum relief valves shall be checked by applying the design gas pressure to the outer tank, followed by evacuation of the outer space to the vacuum setting of the relief valve.
The cleanliness of the API Std 650 carbon steel tank has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API Std 650 carbon steel tank clean can slow down the corrosion of the tank wall and reduce the pollution to the oil. If the inside of the API Std 650 carbon steel tank is not cleaned all the year round, a lot of rust and metal impurities will be produced in the tank. These impurities will cause the oil to slowly oxidize and deteriorate. The impurities mixed into the oil will also block the filter and oil circuit, causing oil supply failure.
