Raising the ILI performance bar higher
New MagneScan now delivers very high sensor resolution with a 12 mm2 (0.18 in2)
sampling area, which is half the industry standard of 24 mm2 (0.36 in2) – and
furthermore, each measurement point is sampled 3 times over, using low-noice,
Tri-Axial sensors, to cover each magnetic field axis.

Greater pinhole probability of detection
 Pinholes have been a 'blind-spot' for traditional ILI tools to date, since
most lack the necessary sensor sampling. The example below shows
the capability of New MagneScan's dense sensor footprint to resolve
a very clear, discernable 2 mm x 2 mm
(0.08" x 0.08") signal, as a result
of detecting a pinhole.

Additional defect characterization benefits
 To
aid data analysts in improving characterization of complex (interactive
or axial) corrosion defects, New MagneScan presents visually powerful
data derived from three magnetic fields– transverse, radial, and axial.
These data sets are combined to achieve enhanced defect
sizing specifications and improved probability of identification (POI).

Enhanced dent discrimination
Discriminating between dents and dents with metal loss can be very challenging.
New MagneScan will deliver integrated reports that visually combine six data
sets (3 axes of magnetic fields, caliper, IMU, and ID/OD) to assist analysts in the
proper classification and prioritization of mechanical damage.

Small bore centerline mapping
 Before GE's development of the new MagneScan it has
been virtually impossible for operators to fully inspect
and map in high resolution six-inch pipelines due to
their small diameters. Centerline mapping establishes
the needed common reference for alignment of all other
datasets and aids in more readily meeting regulatory
compliance & documentation requirements.
Additional benefits include:
- Tighter data set integration to improve stationing of defects
- Detecting bending strain at stress concentrators
(i.e. bends, deformation, spanning, movement)
