CSA G40.21 Gr 300W plates API standard 650 ground supported liquid storage tanks

The safety inspection of atmospheric storage tank, API standard 650 ground supported liquid storage tanks is divided into external inspection, internal and external inspection and comprehensive inspection. External inspection shall be conducted at least once a year, internal and external inspection shall be conducted at least once every three years, and comprehensive inspection shall be conducted at least once every six years. The safety inspection of large atmospheric storage tanks, API standard 650 ground supported liquid storage tanks requires special attention: the parts where the liquid level often fluctuates, the parts that are susceptible to corrosion, and the parts that are deformed and worn during use should be checked.

Under the same sealing effect, the internal API standard 650 ground supported liquid 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 standard 650 ground supported liquid storage tanks external floating roof tank.
