2024 aluminum rod API standard 650 aboveground petroleum storage tanks

Inspection of weld and micro crack of API standard 650 aboveground petroleum storage tanks: the inner and outer surface of API standard 650 aboveground petroleum storage tanks, weld and heat affected zone shall be observed by naked eyes first. 100% ultrasonic testing or 100% penetrant testing are carried out for butt welds of API standard 650 aboveground petroleum storage tanks. For the defects found by 100% magnetic particle inspection, dye detection, 100% ultrasonic inspection or 100% penetrant inspection, the radiographic inspection shall be used again to ensure the accuracy of the test results.

Protection of Plates during Shipping and Storage
Plates shall be adequately protected during shipping and storage to avoid damage to API standard 650 aboveground petroleum storage tanks material plate surfaces and edges from handling (scratches, gouge marks, etc.) and from environmental conditions (corrosion, pitting, etc.).
Plates shall be protected from moisture or stored in inclined position to prevent water from collecting and standing on surface.

The tank wall design of API 650 oil storage tank. Since there is no ventilation pipe directly connected with the outside on the top of the API standard 650 aboveground petroleum storage tanks tank, the ventilation between the inside and outside of API 650 oil storage tank is realized by the respiration valve. The constant pressure of the respiration valve is 0.3kPa, so the pressure on the top of the tank is 0.3kPa.
