The system of pipeline corrosion detection was beneficial for engineer to monitor the corrosion status of buried pipeline and save the maintenance cost.

Multi-channels ultrasonic is dealt with,which is a key technology of in-line inspection of pipeline corrosion.

Using the broad-band ultrasonic inspection technology to develop the research on ultrasonic Pig with rotary probes and transducer array,the data processing for B-/C-scan imaging and 3D imaging of pipeline corrosion flaw was realized.

Based on the corrosion inspection research and comprehensive technical and economic analysis, Corrosion and Protection Research Institute of Shengli Oilfield provides a scenario for fast inspecting and determining pipeline corrosion state without trenching, It includes technique, instruments, inspection procedure for measuring main parameters and error control.
