The paper analyzes and studies the acoustic emission monitoring and phased array ultrasonic testing of steel bifurcated pipe of 800MPa grade strength in hydraulic test. The comprehensive grade of AE location source is assessed, and the structure health is evaluated, the AE characteristic parameters of an important hazardous area corresponding to the load elevated stage and load holding stages are analyzed and compared, and Kaiser effect is verified. PAUT is used to examine the area of great activity located by AE, and the position of welding defects found by PAUT is basically consistent with the AE location map, then the location error of AE is illustrated in the region of irregular shape. The AE and PAUT are of great advantage in hydraulic test of the steel bifurcated pipe.
