TesTex Eagle 2000 Plus Multichannel NDT System
The Eagle 2000 Plus Multichannel NDT System is a fast, accurate, cost effective and field proven system for tube examination from the I.D. It can be used in single channel mode, differential mode, or multichannel mode depending upon the type of inspection required. A full 100% circumferential test is performed over the tube's full length, not just the finite points, as with some other NDT methods. The Eagle 2000 Plus detects and quantifies corrosion, erosion, pitting, cracking and mechanical defects by using the remote field electromagnetic technique (RFET) method, preventing costly and dangerous tube failures. The Eagle 2000 Plus tests straight and U-Bend heat exchanger tubes, bent boiler tubes, finned or unfinned tubes, ferrous or non-ferrous tubes and small diameter pipes. It also provides a baseline evaluation of new or stock tubes.
Features & Advantages:
| || |
- Requires no couplant
- Uses no magnets
- I.D. or O.D. scale have no signal impact
- Standard probe sizes from 0.320" (8mm) to 6" (150mm)
- Test approximately 300 tubes per shift
- Fill factor is not critical (can be as low as 40%)
- Full circumferential coverage over entire length
- Minimal tube preparation
- Wide frequency range allows ferrous or non-ferrous testing
- Real time display with advanced signal processing
- High resolution 3-D color graphics
- Modular system is easily packed for transport

- Single channel probes can operate in either absolute or differential modes
- Multichannel probes allow for smarter defect detection with accurate sizing
- The system can test boiler tubes from either the mud or the steam drum. Using flexible probes allows the bends to be tested with full detection / quantification capabilities. (The inner and outer radius of boiler bends are very susceptible to defects).
- Special flex probes are available for testing U-Bend bundles
- Fill factor is not critical with RFET technology (unlike standard eddy current technique). One size probe will test many different sizes of tubing, making many inspections possible with only a few standard size probes.
- Calibration tubes can be manufactured for virtually any flaw type. This aids in flaw detection through pattern recognition and allows quantification of defect depth and diameter.
Full Length Boiler Tube Inspection
Boiler inspections are performed on drum to drum type boilers as well as straight tube boilers. These tests are full length examinations from the tube I.D. giving quantitative evaluations of each tube. Applications include power boilers, recovery boilers, waste heat boilers, fire tube boilers, dowtherm boilers and related boiler components such as tubular air heaters. With the flaw characterization process, defects such as areas of wall thinning, pitting, cracking, erosion / corrosion, soot blower thinning and flue gas thinning are exposed and evaluated.

Multichannel drum to drum boiler data showing 65% to 75% wall loss near the mud drum bend
Single channel drum to drum boiler data showing 35% to 45% wall loss.
Heat Exchanger Tube Inspections
Heat Exchanger inspections are performed on straight shell and tube exchangers, U-Bend bundles and finned tube exchangers. Applications include feedwater heaters, air coolers / fin fans, chillers / coolers, air heaters / pre-heaters, MSR's, reformers / ultraformers, condensers, reactors and reboilers. Types of defects located in these units are wall thinning, pitting, cracking, vibration / fret wear, erosion / corrosion and steam cutting.

Using a standard 8 channel rigid probe, a 0.039" (1mm) diameter pit, 30% deep, can be detected in a 1" O.D., 0.083" wall carbon steel tube. Other small defects such as circumferential and axial cracks can be detected and quantified using a calibration standard prepared with EDM notches. All defects are sized by phase and amplitude response and number of channels affected.
