Tube Inspection (Eddy Current ET)

We uses ECT (including Remote Field and Near Field technique) to detect pits, corrosion, erosion,
cracking, and others, in carbon steel (RFT) stainless steels, brass, titanium, Inconel, copper, copper-nickel,
and other non-ferrous tubes.
The tubes must be free of obstructions. However, the cleaning required is minimal.

Applications

The main applications of this service are:

The tubes within heat exchangers and boilers are subjected to high temperatures, pressures, and corrosive environments, making them susceptible to degradation over time
Eddy Current (ET) inspection is widely employed for the
examination of these tubes due to its ability to detect and
characterize surface and near-surface defects such as
corrosion, erosion, cracking, and wall thinning

Advantages

The main advantages of this service are:

Fast technique, with up to 1 m/s pulling speed through tubes
Couplants are not needed, consequently contaminants are
not introduced during the inspection
The technique identifies large and small volume pits
100% of the surface of the tubes is inspected, with 360º coverage through the length
All the data is stored for review

Equipment

Equipped with the following devices:

NORTEC 600D (OLYMPUS)
OLYMPUS tube probes for ET/RFT/NFT applications in different tube material, diameters and thickness
Calibration tubes with artificial flaws (notches, SDH, holes…) for different materials, application and thickness
