Technology based at Villary effect, tool has new generation of ferrosonde sensors detects changes in the magnetic field. Technology could detect: Metal loss from 10%, corrosion, defects related to metal loss, changing the pipeline geometry, stress-deformed states, unauthorized tie-ins and repair sites
Remote measurements of magnetic field anomalies caused by defects of various nature
Monitoring inside pipeline with a set of various sensors
Non destructive testing by traditional methods
