GAP MODULE
designed to perform ET and UT examinations from the inner surface of the tubes
special blade probe used for inspection with embedded TOFD probes,
eddy current probe and UT 0°probe
detection and length information of surface flaws conducted by eddy current pro be
UT inspection using TOFD technique for detection and sizing
of circumferential and axial cracks
straight beam ultrasound examination for leak path detection
rotation speed: 0 − 12 °/s
linear vertical speed: 0 − 100 mm/s
linear positioning accuracy: ± 0.2 mm
angular positioning accuracy: ± 0.2°
J-GROOVE WELD MODULE
eddy current examination of J-groove weld shell and nozzle side
designed to cover complex weld geometry
applied array probe (PRO ARCHER)
rotation speed: 0 − 12 °/s
linear vertical speed: 0 − 100 mm/s
linear positioning accuracy: ± 0.2 mm
angular positioning accuracy: ± 0.2°
AUTOMATED SURFACE REPAIR MODULE
removal of flaws discovered by eddy current examination from the J-groove weld’s surface
supported by EddyOne Mending
3 axes of movement
definition of the grinding area based on the surface probing and UT inspection results
built-in safety features with respect to grinding depth
grinding does not affect originally designed structural integrity
depth verification with the second probing
ASR is a non-welding process − no additional source of intensive heat
excellent ALARA results
