(NKK), Hak company and RED company, Russian NGKS company and the like. Some domestic colleges and research institutions are also following the research of ultrasonic internal detection recently, for example, Shanghai traffic university has developed a set of engineering prototypes of a phi 325mm submarine pipeline ultrasonic detection system and a calibration test system thereof, and a Shandong special inspection institute independently develops the first domestic oil and gas pipeline ultrasonic internal detection robot, but the long-distance pipeline detection practicability of the two sets of systems is still under exploration.
