In this study, existing conditions of the subsurface pipeline systems are diagnosed and monitored based on an advanced non-destructive, non-invasive and non-contact magnetometric inspection mechanism to minimize the routine maintenance based intervention on to the piping system also eyeing to reduce the overall diagnostic costs and other related expenses. This mechanism allow operators to detect anomalies in the core metal pipelines from above the ground without excavation or any pre-treatments such as cleaning or coating removal, giving priority to the existing integrity of the pipe. It could predict anomalies even before any actual macro-level defect start appearing on the object to be detected by ILI techniques or any other macro-defect inspection tools. The data generated using this technique is validated by matching the diagnostic data collected using the available conventional techniques following industrial standards. This paper also investigates and demonstrates the effectiveness of the magnetic method for detecting the anomalies in the pipes which are embedded in the soil surface.
