API standard 650 carbon and low-alloy steel tanks semiautomatic arc welding
Under the same sealing effect, the internal API standard 650 carbon and low-alloy steel tanks floating roof API 650 tank can further reduce the evaporation loss compared with the external floating roof API 650 tank. This is due to the shielding of the fixed roof and the gas phase layer between the fixed roof and the inner floating plate, which has more significant heat insulation effect than the double disc floating roof of the API standard 650 carbon and low-alloy steel tanks external floating roof tank.
Generally speaking, the duration of the "exhalation" of the API standard 650 carbon and low-alloy steel tanks is longer than that of the "inhalation" of the API standard 650 carbon and low-alloy steel tanks every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the API standard 650 carbon and low-alloy steel tanks location, open area of the API standard 650 carbon and low-alloy steel tanks, atmospheric pressure, filling degree of API standard 650 carbon and low-alloy steel tanks, etc. When the API standard 650 carbon and low-alloy steel tanks is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.
