Exploration and Application of Metal Magnetic Memory Testing Technology on Bime-tallic Composite Pipelines
Using bimetallic composite pipelines is considered as a relatively safe way to solve the corro-sion problem of highly corrosive oil and gas field surface gathering and transmission pipelines.But there are problems such as pipeline failure and detection difficulty in the current domestic application process.Metal magnetic memory testing technology is applied to detect buried bimetallic composite pipelines.It has been verified by excavation at locations with high risk level of magnetic anomaly,and has achieved good application results in combination with thickness measurement,magnetic saturation-pulse eddy current,and other nondestructive testing technologies.It is clear that the metal magnetic memory test-ing technology can meet the requirements of testing the stress concentration degree of buried bimetallic composite pipelines to a certain extent,and has certain promotion value.
