Imagine a world where checking for corrosion in storage tanks is no longer a tedious, costly, and potentially dangerous task. That's the vision of Southwest Research Institute (SwRI), which has developed a game-changing solution: the magnetostrictive transducer (MST) probe. This innovative tool employs ultrasonic guided wave technology to detect corrosion without the need to empty the tank, revolutionizing the inspection process.
The SwRI MST 8x8 is a flexible strip of eight ultrasonic sensors, each generating acoustic waves that travel along the tank's structure. When these waves encounter corrosion or other flaws, they reflect back to the sensor, alerting inspectors to potential issues. The probe's use of shear horizontal guided waves ensures precision and sensitivity, making it an industry leader in advanced inspection technologies.
"Regular tank inspections are essential across various industries, but the traditional process is expensive and time-consuming," explains Dr. Sergey Vinogradov, a SwRI researcher and author of a recent paper on the MST 8x8. "Our probe eliminates the need to empty and clean the tank, reducing downtime and improving safety by avoiding hazardous, confined spaces."
SwRI's field tests have proven the probe's effectiveness on storage tanks, but its applications extend far beyond. The technology can also be used to inspect ship hulls, wind turbines, rocket bodies, pipelines, and other structures. The probe's eight-sensor array collects data from multiple angles, enhancing accuracy and enabling full matrix capture, which creates detailed 2D maps of the inspected areas.
"The probe's data is processed using an advanced imaging algorithm called the total focusing method, which generates highly detailed maps," Vinogradov adds. "This not only indicates anomalies but also provides a high-resolution map of the structure, helping users assess the extent of corrosion and plan for timely, cost-effective repairs."
One of the probe's standout features is its ability to work with complex geometries, such as curved surfaces and attachments, which often pose challenges for traditional inspection methods. This versatility makes it invaluable across industries, including oil and gas, aerospace, manufacturing, shipping, and municipal utilities.
SwRI plans to make this technology widely available through equipment sales, licensing, and technology transfer to inspection companies. The study detailing the probe's efficacy, "Screening of Corrosion in Storage Tank Walls and Bottoms Using an Array of Guided Wave Magnetostrictive Transducers," was published in MDPI Sensors and is accessible at https://doi.org/10.3390/s26041253.
This breakthrough technology promises to transform the way we approach tank inspections, offering a safer, more efficient, and cost-effective solution. It's a prime example of how innovation can revolutionize industries and improve our world.
