Magnetic Flux Leakage Device for Offshore Oil Pipeline Defect Inspection

Abstract

To ensure the safety of oil transmission, routine inspections of offshore oil pipelines are essential to locate defects or corrosion. This article describes a test device for offshore oil pipeline defect inspection, based on magnetic flux leakage (MFL). The hardware and signal-processing system are described. The inspection device includes an MFL detector, driver robot, data-acquisition system, signal processing unit, and power unit. The device can be used for multi-radius pipelines and various work conditions.
