The landscape of the refining and petrochemical industry is vast; the products diverse. But operators face the same challenges to safety and reliability — issues such as corrosion, cracking and wall thinning.

Without the proper equipment and expertise, damaged areas can be extremely challenging to locate, characterize and size. And the consequences of an error could be catastrophic. Fortunately, you’ve got IIA on your side.

We provide solutions to help refineries and petrochemical plants overcome any inspection challenge, and lower their cost of ownership along the way. Our full-service capabilities — including state-of-the-art laboratories — mean faster turnaround times, cost-effective solutions, and bull’s-eye accuracy.

Schedule your complimentary, on-site facility assessment today.

From remote visual inspection to traditional and specialty NDE, we are experts in the most advanced examination techniques available today. And we are always working to develop the preferred techniques of tomorrow. From ARMUT®’s high-resolution elbow weld images to PASS valve analysis, IIA offers proprietary tools and technologies that are unmatched in the industry.

With 22 field offices and a skilled, mobile workforce, we can be on-site and at your service — usually within hours. Our technicians are ready to hit the ground running because they’ve spent years working with equipment just like yours.

We prove ourselves the first time around, so you only need to make one call the second time around.

Remote Video Inspections (RVI)

Foreign objects can lead to shutdowns, contamination, loss of revenue, and in worst-case scenarios, catastrophic failures. We are the industry leader in the use of RVI tools to safely locate and retrieve foreign objects in your facility. Our explosion-proof cameras can also provide invaluable information about the internal condition of fixed, rotating and hazardous environment-rated equipment, as well as assistance with sinkhole examinations, turnarounds and more.


The in-house experts at IIA developed Absolute Recordable Manual Ultrasonic Testing (ARMUT®) to bring together the best of both manual and automated ultrasonic testing for critical weld examinations. The only system that can capture encoded positional and time data simultaneously, ARMUT can be used by a single technician to examine critical welds and gather extremely high-resolution images that can be stored, shared, and immediately analyzed.


Our patented Phased Array Sectorial Scanning (PASS®) technique allows us to provide an unmatched level of information and insight into valve integrity and performance during operation — eliminating unnecessary and costly valve disassembly. Our PASS® Visualization Software then translates the raw data into a dynamic valve simulation, featuring a 3-D model for easy interpretation and analysis.
