Technical Leadership
Plant System & Equipment Testing
We can help your plant run more efficiently in many areas.
Bolting: threads in flange (TIF)
Our automated and manually deployable scanner system ultrasonically examines flange threads, and easily maneuvers onto and around guide pins or stud hole plugs. Our system accommodates large or small holes and is easily tailored to any flange architecture. Our safe and cost-effective solution does not require crane support — only a small operating crew.
Core Shroud
We provide shroud horizontal and vertical weld examinations using our state-of-the-art technology: AIRIS-CS,™ Upper Shroud Scanner (USS) delivery systems, and a BWRVIP-qualified Phased Array UT (PAUT) data acquisition system.
Dissimilar Metal Welds
We can deliver rapid ultrasonic examination of various pipe weld configurations and bidirectional scanning. Weighing less than seven pounds, our system is ideal for a single operator and its multiple link design and different length scan arms makes it compatible with different pipe sizes (4” and up) and configurations.
BWR Steam Dryers
The Steam Dryer Lifting Rod scanner is a manually deployable X-Y scanner with the ability to conduct vertical scanning and horizontal reference location scanning. The system includes the scanner and the Tomoscan III acquisition system and provides enhanced precision and examination coverage, increased reliability, and easy handling and maintenance.
Heat Exchangers
Our automated and manually deployable scanner system ultrasonically examines flange threads, and easily maneuvers onto and around guide pins or stud hole plugs. Our system accommodates large or small holes and is easily tailored to any flange architecture. Our safe and cost-effective solution does not require crane support — only a small operating crew.
Piping
Our automated and manually deployable scanner system ultrasonically examines flange threads, and easily maneuvers onto and around guide pins or stud hole plugs. Our system accommodates large or small holes and is easily tailored to any flange architecture. Our safe and cost-effective solution does not require crane support — only a small operating crew.
Reactor Generator Nozzles
Our automated and manually deployable scanner system ultrasonically examines flange threads, and easily maneuvers onto and around guide pins or stud hole plugs. Our system accommodates large or small holes and is easily tailored to any flange architecture. Our safe and cost-effective solution does not require crane support — only a small operating crew.
Reactor Pressure Vessels
PDI-qualified examinations use fully automated state-of-the-art PAUT techniques for PWRs and BWRs for vessel shell welds, , nozzle-to-shell welds, nozzle-to-safe end dissimilar metal (DM) welds, and on safe end-to-pipe, as well as elbow welds.
Turbines
Our automated and manually deployable scanner system ultrasonically examines flange threads, and easily maneuvers onto and around guide pins or stud hole plugs. Our system accommodates large or small holes and is easily tailored to any flange architecture. Our safe and cost-effective solution does not require crane support — only a small operating crew.
Storage Tanks
Certified in SNT-TC-1A (Level I, II and III) & CP-189 and in multiple NDE methods, including ASNT Level III, IIA uses our proprietary AIRIS TM 21 tool with our state-of-the-art NDE techniques. The AIRIS 21 can deploy via most tank manways.
Valves
We provide diagnostics and inspection services for a variety of valve configurations. Our patented PASS® Visualization software provides an easy, complete solution for Phased Array UT (PAUT) data analysis. We provide a 3D valve model that allows engineers to interpret and translate field data. An accompanying database tracks valve performance, enabling critical decisions on operability and predictive maintenance without disassembly.
Breadth of Service
Fitness-for-Service (FFS) Evaluations
Once a flaw or damage is identified, our FFS evaluations assess the structural integrity of in-service equipment, such as tanks, piping and pressure vessels, to help plant owners make informed run-repair-replace decisions.
Finite Element Analysis (FEA)
Using advanced computer modeling software, we predict how components perform under real-world stresses like heat, vibration, or impact. This provides precise data for comparison against specifications, codes, and standards.
Service Water System Evaluations / Tmin Calculations
We perform ASME-compliant flaw evaluations of Service Water piping. Combined with our engineering expertise in t-min calculations, IIA can clarify the parameters for safe operations.
Cutting Edge Technology
We are experts in advanced examination techniques, continuously developing tools for the future. Our patented technologies, such as ARMUT® for high-resolution weld images and the AIRIS® RPV and tank robotic scanner, enable us to confidently meet inspection challenges. These innovations allow for safer, more efficient inspections with fewer crew members, reducing radiation exposure and often replacing the need for radiography.
