In addition to the specific requirements of this appendix, all piping within the limitations of 1.3.2 shall fulfill the minimum requirements of ASME B31.3.

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