AN APPARATUS FOR MONITORING METAL PIPES USING PULSED EDDY CURRENT DETECTION AND A METHOD THEREOF

摘要

A metallic pipe monitoring device using pulsed eddy current detection according to the present invention includes: multiple coils arranged at predetermined intervals in the outer circumference of a metallic pipe; a pulse generating unit to apply pulse signals successively to the multiple coils; a signals receiving unit receiving signals induced to the multiple coils by a magnetic field generated by an eddy current induced to the metallic pipe; a signal processing unit extracting a predetermined value from the signals received by the signal receiving unit; and an acquiring unit generating array signals based on the value extracted by the signal processing unit and acquiring the defect information of the metallic pipe. The metallic pipe monitoring device using the pulsed eddy current detection and a metallic pipe monitoring method according to the present invention are capable of providing the metallic pipe monitoring device and the metallic pipe monitoring method capable of monitoring the metallic pipe at ordinary times by nondestructively inspecting a depth, a length, and a position of a defect. Accordingly, the metallic pipe monitoring device and the metallic pipe monitoring method are capable of monitoring the metallic pipe at ordinary times by nondestructively and periodically detecting defects of the metallic pipe, thereby ensuring safety by preventing damage to peripheral equipment and casualties due to the defects of the metallic pipe and preventing economic losses.
