CSA G40.21 grade 350W plates API 650 partially anchored liquid-storage tanks

The welded API 650 tank in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure API 650 partially anchored liquid-storage tanks is permitted when additional requirements are met.

Ultrasonic Examination of Butt-welds in Plates
Butt-welds in all tank wall courses subjected to a maximum actual operating membrane tensile stress, perpendicular to the welded joint, greater than 0.1 times the specified minimum tensile strength of the API 650 partially anchored liquid-storage tanks plate material shall be completely examined.
Butt-welds in API 620 oil tank wall courses subjected to maximum actual operating membrane tensile stress, perpendicular to the welded joint, less than or equal to 0.1 times the specified minimum tensile strength of plate material shall be spot examined in accordance with Figure Q-2.

Oil storage tank with floating roof structure: The floating roof in the API 650 partially anchored liquid-storage tanks oil storage tank can effectively reduce the volatilization consumption of oil, because the gas space on the oil liquid surface in the floating roof storage tank is small, the exhaust volume is low, and the breathing loss is very small. That can reduce the volatilization loss caused by the "big breath" of the API 650 partially anchored liquid-storage tanks. Strengthen the inspection and maintenance of API 650 partially anchored liquid-storage tanks: regularly check the sealing conditions of oil storage tanks, and check and maintain important auxiliary equipment to ensure good sealing performance.
