【Abstract】 A pig is a equipment for pipeline internal corrosion detection. The overseas applications of magnetic leakage intelligent pigs and ultrasonic intelligent pigs are introduced. And the constituent and operating principle of the intelligent pigs are discussed. It is pointed that there is the gap between our country and the advanced countries in pipeline internal corrosion detection technology. some problems are proposed which need to be solved urgently.更多还原
