Structural Integrity has a long history of developing innovative Non-Destructive Evaluation (NDE) applications, tools, training, and services, supported by extensive engineering expertise. These capabilities enable our highly experienced staff to complete essential inspections and documentation required for any NDE integrity project.
UT ILO RT
For new construction and replacement weld examination services, SI is well-versed in code-compliant ultrasonic examinations performed in lieu of radiography. Code-compliant UT examinations can be performed per the requirements of B31.1 and B31.3, including applications of ASME Case 189. Since these exams can be conducted concurrent with fabrication activities (i.e., no radiation source), results are higher welding production rates and more timely delivery of results for any repair needs.
Corrosion Mapping
SI uses a high-resolution ultrasonic dual-matrix phased array probe for thickness mapping. This probe can be used with an encoding device or scanner to generate a detailed map of component thickness over large areas. SI can use our SIPEC technology to map thickness through the coating layer for components with thick coatings, wraps, or liners. Advantages include:
Digital data records allow third-party verification and routine monitoring
Non-Invasive Inspections (NII)
Encoded semi- and fully automated scanning available
Manual encoded examinations with LATITUDE™
On-line inspections, even at elevated temperatures
System Internals
Structural Integrity provides NDE services for inspecting the walls and floors of tanks and other non-pressurized vessels using a variety of GWPA, SIPEC™ ECT, EMAT UT methods and technologies.
Tank walls and the floor-to-wall region are inspected to EPRI license renewal guidelines using GWPA techniques
Tank floors receive 100% inspection coverage per EPRI guidelines via manual techniques or precision robotics
Robotic examinations allow submersible inspections within full tanks to simplify implementation and limit risk
Absolute Acoustic Positioning precisely positions and repositions the robot and probing device for subsequent inspections
Pressure Vessels
Structural Integrity provides integrated engineering solutions for High-Pressure Equipment by applying advanced engineering tools and inspection techniques. Our vast experience combines to provide solutions that can reduce life cycle costs, reduce downtime, and extend equipment life, such as our novel SI In-Vessel Automated Scanner (SIIVAS) system.
CASS Components
In addition to current ISI requirements, License Renewal requires specific attention to CASS Cast Austenitic Stainless-Steel components commonly found in RCS Main Coolant Loops and Pressurizer Surge Lines. Industry research, combined with our ultrasonic testing expertise and culture of innovation, has resulted in SI developing the first practical commercial solution to inspect CASS: Ultrasonic Procedure SI-UT-228 i.a.w. Code Case N-824 / ASME Section XI, App III, Supp. 2
Heavy Lift Rigs
SI provides certified, experienced personnel, equipment, and procedures for safety-related and non-safety-related applications for heavy-lift equipment testing, such as reactor head and internal lift rigs, ISFSI yokes, etc.
State-of-the-art flaw detection using acoustic emission technology
Significantly reduces inspection time and associated dose
Global inspection results in targeted recommendations
Raw Water Piping
Innovative, multi-technology approach to rapidly scanning and characterizing extensive portions of service water/emergency cooling systems. It can be applied to buried or above-ground piping.
GWT will scan long piping sections and identify areas with general corrosion
Corrosion mapping to develop thickness distributions/profiles in local regions with significant degradation
Detailed PAUT to characterize worst-case wall loss
Weld Overlays (WOLs)
SI examines WOLs installed preemptively or in response to inspection findings. Integrating NDE with engineering and welding activities optimizes overlay design conditions and minimizes implementation time. Accurate characterization of WOL geometry and subsurface conditions enables detailed life assessment of the as-installed repair.
Turbine & Generator Rotors
Solutions to ensure a safe, reliable, and efficient operation.
Decades of expertise in technology development and application
Faster, less invasive, and lower cost alternative to OEM inspections
Complete open/clean/close services in combination with trusted partners
Dissimilar Metal Welds (DMWs)
SI performs examinations of DMWs following Section XI, Appendix VIII requirements via PAUT methods. The scope and execution of these exams can be customized to address specific needs, with deployment options ranging from fully manual to manually encoded to fully automated. Results are rapidly processed and validated by experienced field technicians to support prompt decision-making in the event of findings.
Buried Piping
Coating Assessment
GWT to identify remote/inaccessible areas with wall loss
Local UT to characterize defects (manual or automated)
