API 650 carbon steel storage tanks vertical shell joints

Under the condition of static storage without receiving and sending operation, the temperature of gas space, evaporation rate, depth and pressure of vapor in the API 650 carbon steel storage tanks will change with the change of temperature and pressure in a day. The oil loss caused by the process of discharging oil vapor and inhaling air gas is called "small breathing" loss, which is also called static storage loss of oil tanks.Responsibility of API 620 Storage Tanks ExaminerThe inspector shall ensure that all materials used in tanks constructed according to the rules in this standard comply in all respects with the requirements of these rules. This shall be done either by witnessing mill tests or examining certified mill test reports supplied by the Manufacturer. Storage tanks API 650 carbon steel storage tanks constructed according to the rules in this standard shall be inspected and tested in accordance with the sections that follow. The inspector shall carefully follow the fabrication and testing of each tank and shall make sure that they comply in all details with the design, fabrication, and tests specified in these rules.Under the same sealing effect, the internal API 650 carbon steel storage 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 650 carbon steel storage tanks external floating roof tank.The company focuses on quality building, continuously create greatest value for customers, and has achieved good economic and social benefits.
