Phased Array

At Eagle Eye NDT, ensuring the integrity of your assets goes beyond surface inspection. Phased Array Ultrasonic Testing (PAUT) offers a revolutionary non-destructive testing (NDT) method that utilizes focused sound waves to detect hidden anomalies within materials. This advanced technique empowers you to proactively identify potential issues and safeguard the structural health of your critical components.

Applications: Safeguarding Assets Across Industries
PAUT's versatility makes it a valuable tool for various industries that rely on the structural integrity of their components:
Oil & Gas: Inspecting pipelines, pressure vessels, and welds for cracks, corrosion, or other anomalies, safeguarding operational safety and environmental protection.
Petrochemical: Ensuring the integrity of piping systems, vessels, and processing equipment to minimize risks associated with leaks, failures, and potential hazards.
Power Generation: Evaluating welds, critical components within boilers and turbines for potential defects, promoting reliable power generation.
Welding & Fabrication: Verifying the quality of welds in new construction projects and ensuring the integrity of welds in in-service components.
Aerospace: Inspecting critical components in aircraft for hidden flaws, upholding the highest safety standards in the aviation industry.
Limitations to Consider
While PAUT offers significant benefits, some limitations exist:
Complexity of Operation: PAUT requires a high level of expertise to operate and interpret the data effectively. This may necessitate additional training for inspectors compared to conventional ultrasonic testing.
Higher Equipment Cost: PAUT equipment is typically more expensive than conventional ultrasonic testing tools. However, the increased efficiency and versatility may offset the initial investment in some cases.
Material Limitations: PAUT sound waves may be attenuated or scattered by certain materials, limiting their effectiveness in some applications.
Surface Roughness: Rough surfaces can affect the quality of the ultrasonic signal, potentially impacting the accuracy of the inspection.


Conclusion: A Powerful Tool for NDT
Phased Array Ultrasonic Testing (PAUT) stands as a powerful tool in the NDT arsenal. Eagle Eye NDT's team of experts, coupled with our advanced PAUT technology, ensures comprehensive and efficient inspections. By implementing PAUT, you gain deeper insights into the health of your assets, promote operational safety, and optimize your maintenance strategies. However, it's crucial to consider the limitations of PAUT and ensure proper expertise is available to maximize its effectiveness for your specific needs.

Shaping the Sound: How PAUT Works
PAUT probes differ from conventional ultrasonic probes. They contain multiple piezoelectric elements that can be controlled individually. By manipulating the timing and firing sequence of these elements, Eagle Eye NDT technicians can:
Change the Shape of the Ultrasonic Beam: Unlike conventional probes with a fixed beam profile, PAUT allows for steering and focusing the sound waves. This optimization ensures efficient penetration and targeting of specific areas within the material.
Adjust the Focal Point: The focal point of the sound waves can be electronically controlled, directing the inspection zone to the precise depth within the material.

Flexibility and Efficiency: The Advantages of PAUT
PAUT technology offers significant advantages over conventional ultrasonic testing:
Versatility: A single PAUT probe can replace multiple conventional probes with different beam angles. This simplifies complex inspection setups and reduces the need for specialized equipment.
Real-Time Imaging: PAUT provides real-time visualizations of the sound wave interactions within the material, allowing inspectors to make informed decisions during the inspection.
Digital Recording and Reporting: The data acquired during the inspection can be directly recorded digitally, streamlining reporting and certification processes.
Reduced Inspection Time: The ability to electronically steer and focus the beam eliminates the need for multiple probe manipulations, resulting in faster inspection times.
Focused Scanning: PAUT utilizes multiple elements to create a highly focused sound wave, enabling the detection of smaller defects compared to conventional ultrasonic testing.
