AcousticEye Dolphin G3 Enables Advanced Tube Inspection for Heat Exchangers

Enhanced NDT Tube Inspection System is Fast, Easy, and Reliable
AcousticEye, the leader in non-invasive tube inspection solutions for the heat exchanger market, has unveiled the Dolphin™ G3 tube inspection system. The G3 is based on the same breakthrough Acoustic Pulse Reflectometry (APR) technology used in the original Dolphin, which has been successfully utilized by customers worldwide since it was first introduced last year. The Dolphin G3 is ideally suited for testing heat exchanger systems across industries such as oil and gas, chemical, and power-generation markets. 






“Our company has been very impressed with AcousticEye’s technology since we first started using it last year, and we’re looking forward to upgrading to the Dolphin G3 for all of our tube inspections going forward,” said Hans Felius, CEO of Sound Tube Testing. “The Dolphin system has enabled us to offer fast, accurate and unique tube inspections to all of our customers, thus enabling 100% coverage of the tubes in a very short time – none of which would have been possible with other testing methods. With the Dolphin we save our customers time and money due to increased performance and efficiency. The Dolphin has greatly increased our revenues, giving us the opportunity to perform many more inspections in a given time.”

With existing technologies, heat exchanger users are typically limited to sample-testing well under 10% of deployed tubes. AcousticEye’s Dolphin system is a non-invasive, non-destructive testing (NDT) technology that enables inspection of heat exchanger system tubes of every configuration, size, and material – aspects that have inherently limited the effectiveness of traditional invasive methods. The accompanying software produces automated, repeatable results that are consistent, comprehensive, objective, and actionable, enabling anyone to conduct and analyze inspection data. The automated analysis of the test results removes the historical need to rely on the interpretation of experts.

Features of the Dolphin™ G3 Tube Inspection System:

Fast
Fully inspect each tube in less than 9 seconds, regardless of length, configuration, or material
Inspect tubes up to 10 times faster than all previously existing methods
Test 100% of heat exchanger tubes, dramatically decreasing testing and facility shut-down time
Software automatically detects and numbers tubes, producing a complete tube sheet map in seconds instead of hours

Easy
Ruggedized, lightweight main unit (8 kg)
Compact, handheld probe (1.1 kg) with LCD screen for better navigation
Computer-based analysis and easy-to-read reports
System can be learned and implemented quickly with only a two-day training course

Reliable
Higher sensitivity and improved probability of detection
Works with any tube material and configuration (e.g., bends, U-tubes, fintubes, spirals)
Optimized signal to noise ratio (SNR)
Identifies hard-to-detect bulges, end-of-tube erosion, fouling and inward dents

“Our customers are quickly realizing the value of our inspection technology because of the amount of time, money, and hassle it can save them,” said Brenda Zeitlin, Vice President of Business Development at AcousticEye. “By introducing an enhanced Dolphin system with added functionality, we expect to accelerate the product’s wide-spread adoption in the heat exchanger market.”

According to Nadav Ofir, Senior Consultant, Frost & Sullivan, “AcousticEye’s technology significantly simplifies the entire heat exchanger inspection procedure, enabling 100% inspection of tubes in a significantly shorter time. In addition, AcousticEye's analysis software reduces the dependency on NDT technician availability, a limiting factor in the industry. Overall, the AcousticEye solution brings a very positive message to sectors where small diameter tubes are utilized.”

About AcousticEye

AcousticEye Ltd. was established in 2005 by Tal Pechter and Dr. Noam Amir to bring acoustic technology to the NDT (Non-Destructive Testing) industry. The company develops, manufacturers, and markets mobile and embedded tube inspection devices. AcousticEye’s patented technology offers accurate and rapid single point inspection of inaccessible tubes. The company’s Dolphin is unique in its ability to quickly find and accurately locate defects in complex tube systems regardless of their material, without the need for physically traversing a probe along the tubes.

Aircraft Visual Inspection

Figure: Boeing 777 aircraft Commercial aircrafts are frequently inspected visually. There is a primary inspection called "walk around check" both in the line and the base, transit checks, daily check, weekly check, A check, B check etc… Line is the more about the quick checks while aircraft is in the park or in between flights. Base is mostly the hanger, where hard checks, repairs take place. A qualified engineer walk around the aircraft and inspect structural items visually. Engine is also checked during the walk around checks. There engineer watches for oil leaks, structural damages in the engine, inlet of the engine for composite parts fixtures to the structure, fan/first stages of the compressor, last stages of the turbine for deterioration or damages , or any unusual changes of the engine. In this example shows how, engineer/Pilot carry on a walk around inspection of a Boeing 777 aircraft. Figure: Walk around inspection of a Boeing 777 1. Left Mid Fuselage

Eddy current method (ET)

Short research about the history of eddy current The first person to observe current eddies was François Arago (1786-1853), the 25 th president of France, Who was also a mathematician, physicist and astronomer.1824 He discovered what has been called rotatory magnetism, and the fact that most bodies could be magnetized; these discoveries were completed and explained by Michael Faraday (1791-1867). In 1834, Heinrich Lenz stated the principle that defines how the properties of the test objects are communicated back to the test system. Lenz's law states that the direction of current flow in the test object will be such that its magnetic field will oppose the magnetic field that caused the current flow in the test object. This means, in practice, the eddy currents communicate with the test coil by developing secondary flux that cancels a portion of the coil's flux equivalent to the magnitude and phase of the flux developed by the eddy currents.   Léon Foucault (1819-1868) However,

Eddy current Theory

Eddy current theory is based on electromagnetic induction. That means, a variable magnetic field can induce an electric current on a conductor which is separate to the source of the magnetic field, and also vice versa, which is an electric current generates a magnetic field. Similar theory is used for the magnetic particles inspection as well. Electromagnetic induction is used in many applications such as, Transformers, Electric motors, Generators, etc...   In the field of Non destructive testing (NDT), we manipulate with this theory which I mentioned above, and try to find surface defects or/and shallow internal defects of ferromagnetic materials.
