"ECTT using bobbin probes is commonly used for inspection of condensers, coolers, steam generators and heat exchanger tubes."

ECTT using bobbin probes is commonly used for inspection of condensers, coolers, steam generators and heat exchanger tubes. It is a very fast and sensitive electromagnetic testing technique for inspection of non-ferromagnetic materials. Eddy Current are induced in the tubes by an alternating magnetic field generated from de probe. Flaws will interact with the induced current and returning a different magnetic field to the probe. This variation is translated to changes in impedances measured by an instrument.

 

TÜV AUSTRIA proposes in-situ examination and inspection of new tubes according ISO and ASME standards. Our inspection procedures use multifrequency technology with mixing channels to surpass all inspection standards. Approximately 400 to 600 tubes (6m long) can be inspected in one normal working day. All data is saved, and a report is generated the same day.
