API Std 650 SUG II tanks self-anchored

API 650 external floating roof storage tanks are generally called external floating roof API Std 650 SUG II tanks tanks, which means that the storage tanks are externally open tanks without a dome design, and are equipped with vertical floating roofs. API 650 external floating roof storage tanks are usually used for large More than 20,000 cubic meters of open steel API Std 650 SUG II tanks storage tanks for storing volatile petroleum products such as crude oil, gasoline, kerosene, etc.

Generally speaking, the duration of the "exhalation" of the API Std 650 SUG II tanks is longer than that of the "inhalation" of the API Std 650 SUG II 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 Std 650 SUG II tanks location, open area of the API Std 650 SUG II tanks, atmospheric pressure, filling degree of API Std 650 SUG II tanks, etc. When the API Std 650 SUG II 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.

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 Std 650 SUG II 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.
