Application
Internal tube inspection
Principle
The cylindrical geometry of probes and their small possible diameter enable them to be inserted into tubes to inspect them from the inside in TOFD mode. The orientation of the transducers enable longitudinal or circumferential defects to be detected.
Principle of circumferential defects inspection
Principle of axial defects inspection
Advantages
- Inspection feasibility
- Sensitivity
- Bandwidth
General Characteristics
These transducers are adapted individually to the inspection constraints, and in particular to the handling, plating and coupling mode.
