Development of a New Intelligent Pig Based on Intense Magnetic Memory Technique

The principles and advantages of a new type of non-destructive testing technique—Metal Magnetic Memory (MMM) technique—is briefly introduced, and the Intense Magnetic Memory (IMM) technique under conditions of high intense remanence is put forward. As application in the field of pipeline inspection, a new intelligent pipeline inspection system based on cup-type pig is developed. This device consisting of a hardware system and a software system has much advantages as compact structure, excellent detection capability and achieving the integration of pipeline pigging and detection. Compared with the previous non-destructive testing technology, the biggest advantage is that it can accurately determine the stress and strain concentration area (which always develop into defects) to achieve the early warning of pipeline defects, not just detection of existing defects such as corrosion, cracks and etc. The accidents risk of long-distance gas pipeline can be effectively reduced.
