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

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

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

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

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

Maintenance with Traditional Technologies Typical Scenario Opening Cleaning Overlapping Testing canceled Reporting Plugging Closing Typical refinery loses between $1.2 and $3 million dollars for each day the turnaround went beyond its planned time

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)

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

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” …

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

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

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.

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

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!

Step 1: Map out site and work plan 2 3 1 2 10 11 3 13 4 12 14 5 15 16 7 6 20 30 21 31 32 22 33 23 34 24 35 36 26 25

Step 2: Set parameters

Step 3: Take the measurements Maybe a picture of a measurementbeing made? Notsomuch to show anythingspecific, but to stick to the 5 step flow

Step 4: Set thresholds Erosion Pitting 30% 20% 60% 80% Hole Blockage 1%

Step 5: Generate Report & Analysis

Generate Report & Analysis Approve GOOD NEWS The software finds all the faults for us and we just need to verify the results

Acoustic Eye – Advantages Non-Invasive Cannot get stuck, cannot damage tube FAST Less than 10 seconds per tube Any tube configuration Bends, valves bulges, fins Any tube material Ferrous, non-ferrous, plastics, etc Accurate Indicates location, size and defect type Easy to operate Short training course Computer interpretation Objective, consistent and actionable results Digital records Archive, retrieve, compare, transfer data No Detection of OD If no sign in the ID
