1. Finally. Inspect every tube.
Fast, Accurate, Non-Invasive Tube Inspection

2. Announcing: The End of Sampling
Inspect all tubes, with immediate results
Easy to operate: up and running immediately
Lower costs per inspected tube
Less personnel and time needed during shut downs
Wide range of applications

3. A Major Concern in All Industries Tube defects causing failures
How Tubes Fail
A Major Concern in All Industries Tube defects causing failures
Corrosion
Pitting
Blockages
Leaks

4. NDT Traditional Technologies
Testing for Non-Ferrous tubes
Eddy Current (conventional)
Testing for Ferrous tubes
Full/Partial Saturation Eddy Current (PSEC)
Remote Field (RFT)
Magnetic Flux Leakage (MFLT)
Technologies for all materials
IRIS (Internal Rotating Inspection System)
Remote Visual Inspection (RVI)
Laser Surface Mapping – LOTIS

5. Limitations of NDT Technologies
Require physical traversal of the
entire length of the tube with a probe.
Major limitations on bent tubes
Time Consuming
Dependent on wall material
Requires consumables – inventory management !
Do not apply to narrow or wide diameter tubes
Some need on calibrate on known faults
Require highly skilled certified personnel to interpret the results

6. Maintenance with Traditional Technologies

Typical refinery loses between $1.2 and $3 million dollars for each day the turnaround went beyond its planned time

7. Market Needs No sampling: capable of doing 100% testing
FAST and Automated inspection method
Ability to inspect any material and any tube configuration
Remove as much of the human factor as possible
(availability and judgment)
Use generic probes (avoid disposable problem)

8. The Solution AcousticEye Dolphin G3™
Ultra Fast, Non-Invasive Heat Exchanger Tube Inspection
Up to 10 times faster than current offerings
Inspects any tube (1/2” – 1.5”, soon up to 4”)
Objective computer-based interpretation of test results

9. Looking at Acoustic Pulse Reflectometry
Not only is it Non-Destructive
It goes one step further: Non-invasive!
… sound waves act as a “virtual probe” …

10. Technology Acoustic Pulse Reflectometry (APR)
Probe injects an acoustic pulse down the tube
Records and analyzes the reflected signals
Determines exact location, type and size of tube defect

11. The Core Technology
Acoustic Pulse Reflectometry (APR) is based on one dimensional acoustic waves propagating in tubes:
Schematically:
Excitation pulse:
Reflections:
Soundpulse
Loudspeaker
Tube adaptor
Microphone

12. Typical defects Local blockage: degradation:
(deposits, dents, welding material) (ID expansion, pitting, corrosion) t
Reflection from a
Local blockage
Reflection from a
Local degradation
Each defect has its own signature!
Signature indicates:
exact defect location, defect type and defect size.

13. Quantitative Information
Defect type: hole, blockage, corrosion/erosion and pitting
% Wall loss
Defect size
Distance in tube

14. Putting the Dolphin™ to Work
Map out the site and the work plan Set up the inspection parameters Take the measurements Set your inspection thresholds Generate Report and analyze results 1 2 3 4 5
Nowhow easy is an AE APR inspection!
