Research on External Corrosion Detection System for Low-Pressure Urban Gas Pipelines
As a method of pipeline quality inspection,non-destructive test can adopt multi-channel magnetic flux leakage test technology.The external corrosion in pipelines can be detected by using the internal detection crawler to enter the pipeline to track the health of the pipeline in use,and provide a reliable basis for the evaluation and renovation work of pipelines.The magnetic flux leakage probe structure,magnetic flux leakage detection system,the composition and function of the junction boxes structure are introduced in detail.The system validation is verified by steel pipe defects sample and simulated pressure test.
