API standard 650 tanks site-specific response spectra

Ultrasonic testing can find the internal defects of API standard 650 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 standard 650 tanks and so on metal oil tanks. The feature of this method is convenient and fast.
