Penetration tubes
Application example

Probes

Extra flat probes : < 2 mm thickness
Integrated water coupling system

Set of extra flat probes for penetration tubes inspection

Techniques

TOFD technique for axial defects
TOFD technique for circumferencial defects
L0° Pulse echo technique for thickness measurement

Automated inspection with a sword
Coupling with water film

The probes are inserted in a 2.5 mm gap around the penetration tubes

Benefits

Electroacoustic performances including bandwidth, in spite of the small thickness of the probes

Inspection feasibility thanks to miniaturised probes

Reliability in industrial using conditions including radiation
