API 650 low-alloy steel tanks with internal floating roofs

Ultrasonic testing can find the internal defects of API 650 low-alloy steel tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API 650 low-alloy steel tanks and so on metal oil tanks. The feature of this method is convenient and fast.
