At present,on-line testing method for underwater pipeline corrosion on both side of pipe wall is that a intelligent testing pig was put into the pipeline and pushed by fluid medium. The intelligent testing pig mainly based on the principle of magnetic leakage, ultrasonic & eddy. The paper introduced the principle, structure, advantages & defects for the 3 types testing technology.
