Other applications include air cooler fins and fans, tubular air heaters, and certain types of short-run plant piping.

The Eagle 2000 uses RFET probes that have eight (8) sensors equally spaced around the probe’s circumference (smaller diameters may have four or six sensors).

Eight sensors allow real time, 3-D, color graphic display showing the tube circumference as if the tube were split open and laid flat. Because these discreet pick-up sensors are very small–only a few millimeters in diameter–they have higher resolution and greater detection capabilities for small flaws such as pitting.

The Eagle 2000 detects and quantifies flaws such as baffle cutting and fret wear, erosion and corrosion, pitting, soot blower thinning, flue gas erosion, and steam impingement.

Cracking is also detectable with suitable adjustments to the pick-up coil configuration and proper calibration.

Advantages over Competing Technologies

Other inspections methods for carbon steel tubing are internal rotating inspection system ultrasound (IRIS UT) and magnetic flux leakage (MFL).

The IRIS UT method requires extensive tube cleaning for the technology to work because the ultrasonic signal does not easily penetrate through oxides, scale, deposits, or debris. If the tube’s ID surface can be cleaned down to near bare metal finish, the IRIS UT technique can be successfully applied. TesTex does offer IRIS UT inspections as a service.Magnetic flux leakage testing also requires substantial tube cleaning because the flux leakage probe needs to have a good “fill-factor” (snug fit) compared to the tube’s ID. Because the MFL employs magnets in the probe heads, the probes collect any magnetic deposits that are remain in the tube. While the IRIS UT method has very good flaw quantification capabilities, the MFL method is less quantitative and more qualitative. The TesTex Eagle 2000 Multichannel System does not require extensive tube cleaning because the RFET system allows for usage of probes that do not need a tight fill-factor compared to the tube’s ID. RFET probes do not use any permanent or electro-magnets; therefore, the RFET probe heads do not collect any magnetic deposits or debris. The TesTex Eagle 2000 Multichannel System is quantitative with usage of the proper calibration standards.

Applications :: TesTex-NDT

While they are very different structures, feedwater heaters, heat exchangers, and finned tubes can be inspected by the same TesTex product set. TesTex equipment is used for the non-destructive testing of many vessels, structures, and systems, including. Our software and optional report generator is available for use on all three types of structures and vessels.


Technology :: TesTex-NDT

TesTex has non-destructive testing products that scan external surfaces like the outside diameter of tubes and pipes as well as internal surfaces like above-ground tank floors and the internal diameter of tubes and pipes. TesTex products span a variety of non-destructive testing methods to discover flaws in tubes, pipes, tanks, and other surfaces, and structures. Our testing methods work on ferrous and certain nonferrous materials.
