(SMART PIG), through the movement of the pig in the pipeline, to achieve the purpose of detecting pipeline defects.
The following are some of the more widely used methods:Diameter detection technology,Leak detection technology,Magnetic flux leakage detection technology,Piezoelectric ultrasonic testing technology,Electromagnetic wave sensing technology.
