MagFlux-EX

MagFlux combines rotating and encircling sensor arrangement for detection of longitudinal and transverse defects on seamless tubes

DC Magnetic Flux Leakage Inspection of Seamless Tubes for transverse, helical and longitudinal defects on the OD and the ID.

Overview

A strong DC magnetic field is applied to the seamless tube.  Lines of magnetic flux are contained within a tube without discontinuities.  However, a flaw effectively reduces the local cross section, and results in local near-saturation within the tube.  Some flux lines escape the tube at such locations.  These are picked up by hall sensors arranged optimally.

Applications

  • MagFlux-RT for Rotating Head Inspection for Longitudinal Defects
  • MagFlux-ST for Static Inspection for Transverse Defects Up to 512 channels
  • Both types can be integrated within a single system depicted above.
  • ID / OD defect indication
