Our patented ARMUT® utilizes QR code film on complex geometry to examine critical welds and gather extremely high-resolution images, and the innovative and patented PASS® technology and examination method assists in making critical decisions regarding valve operability and predictive maintenance.
While we provide conventional and advanced inspection methods, such as visual and ultrasonic inspections, magnetic particle and penetrant testing, we also have proprietary technology to aid in inspection speed and reliability.
Some of our proprietary technology is used in lieu of radiography, which provides a safer testing environment while working with fewer on-site crew members, allowing other plant personnel to simultaneously continue work on their tasks.
In addition, our patented AIRIS® technology along with an ROV are deployed and used to scan components inside reactor vessels as well as inspection of the CST and RWST.
IIA also uses Remote Visual Inspection techniques and technology to maintain FME protocols. These tools are used to locate and retrieve foreign objects which can cause contamination and lead to shut-downs resulting in loss of revenue and catastrophic failures.
We employ the best in the business, deploy the most accurate equipment, and provide the highest quality methods. Our quality service, inspection, maintenance, and emergent service helps avoid shut-downs, restore reliable operations, and assist in making critical decisions for your plant..
