The utility model discloses a prevent blowout pipeline line ultrasonic wave phased array formation of image detection device, the utility model relates to a be the host computer by ultrasonic wave phased array detecting instrument, scanning apparatus, coupling device are formed for auxiliary device. Be it phi 127mm to be used for detecting the external diameter phi 196mm's area lacquer layer prevent the blowout pipeline line time, select to correspond the probe of size, promote scanning apparatus along body axis reciprocating motion, cover the body circumference at every turn and be not lessthan 120, divides to accomplish for 3 times and scans. Look into the in -process sweeping, integrated application A sweeps and looks into that wave form, B are swept, C sweeps the detection technique,and ultrasonic wave phased array detecting instrument is real -time to be shown to sweep and look into defect image, wave form, the multi -angle reflection detection condition to judge the blowout pipeline spool physique volume of the preventing condition. Whole testing process was no longer than 10 minutes.
