RoboPipe was built to inspect petrochemical platforms pipes for cracks or corrosion. It can pass between two pipes, through a space of 88 millimeters; also, and grips magnetically to climb up a vertical pipe passing welded joints. It carries a camera and sensors. The camera RoboPipe carries operates under humid conditions, has high resolution which allows it to provide enough details via photos and video. RoboPipe performs corrosion inspection with ultrasound in order to locate and measure the inner pipe damage. Use of ultrasound technology allows it to measure the thickness of the pipe and pinpointing variations which occur due to damage. After detecting damage, the camera is used to visually verify external corrosion.
