15m diameter API 650 carbon steel storage tanks
Inspection of weld and micro crack of API 650 carbon steel storage tanks: the inner and outer surface of API 650 carbon steel 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 650 carbon steel 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.
