FLUX LEAKAGE ROTARIES
Magnetic Flux leakage (MFL) non destructive test systems accurately
detect defects in heavy-wall magnetic tubing, including oil country
tubular goods (OCTG), bars, and parts. Systems are available in sizes to
handle up to 500 mm diameter and 19 mm wall thickness tubes. Transverse
and Longitudinal rotaries detect surface defects as small as 5% on OD
and 5% on the ID as well as defects within the wall, depending on
material type and condition can be detected.
ROTOFLUX® ELECTRONICS
The electronics are capable of differentiating between ID and OD
defects, using a unique multiprobe feature which allows convenient
operation at greater speed. A flux measurement circuit is included to
indicate whether the test piece is properly saturated. To detect
longitudinal defects, the material under test is driven through rotating
headplates that include transverse magnetizing coils and test
probes.MAC also offers
Rotoflux systems
to detect transverse defects where the magnetizing poles are placed in a
fixed position perpendicular to the axis of the material under test,
and the sensors are rotated around the test piece.
