Advanced Non-destructive Evaluation (NDE)
Creep / Service Damage Detection

Finding in-service damage in high temperature piping systems subject to creep requires different skills and procedures than performing a code-acceptance inspection.  SI’s Non-destructive evaluation (NDE) professionals have been trained in advanced NDE techniques specifically designed for finding damage to equipment operating at high temperature and high pressure, including components made from advanced materials such as Grade 91.  Once critical locations are determined, Structural Integrity’s NDE professionals perform high energy piping inspections with the latest in tools, technologies, and techniques.  Inspections for service-induced damage employs time of flight diffraction, linear and annular phased array technologies for girth welds and seam welded pipe. Combined with our expert materials testing and engineering services, SI can provide its customers with reliable component life assessments.

Weld Acceptance Examinations

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. Additionally, SI has developed techniques and procedures for performing UT in lieu of radiography examination in support of waterwall and tubing replacement activities. Since these exams can be conducted concurrent with construction activities (i.e., no radiation source), this allows for higher welding production rates and more timely delivery of results for any repair needs. Once flaws are accurately identified and characterized, SI’s engineers can assist with appropriate mitigation measures, including repair.

Nuclear Non-destructive Evaluation (NDE)

SI has a long history in the development and application of ultrasonic testing in the Nuclear industry, accomplishing a number of industry firsts:

  • First to apply Phased Array UT (PAUT) in lieu of radiography on a ASME Class 1 component, helping to pave the way for a shift in how the industry approaches these examinations (2005).
  • Fiirst to develop and qualify a manual PAUT procedure for the examination of weld overlays, reducing the inspection times by more than a factor of five, at the time. (2006)
  • First to develop and qualify a manual PAUT procedure for the examination of dissimilar metal (DM) welds (2008)
  • First to develop and qualify an automated PAUT procedure capable of examining heavy-wall, full-structural weld overlays installed on main loop RCS piping (2010)
  • First to develop, qualify, and deploy a manual-encoded PAUT procedure for the examination of DM welds, eliminating the need for cumbersome automate scanning equipment and made possible by our development of the LATITUDE™ non-mechanized encoding technology.

Corrosion Mapping

Be it general, flow-accelerated, microbiologically induced, or of another form, internal corrosion of piping and pressure vessels is a significant issue in all the markets served by SI. Often, UT thickness testing is completed manually with the only record of the examination being a report listing the nominal wall thickness and the minimum thickness measured. Adjacent areas that may have less overall wall loss from corrosion can potentially go undocumented. In other applications, UT thickness testing may be completed using a relatively coarse grid over a large area, resulting in a sampling of thickness measurements, though far from a map of the internal topology of the pipe.

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.

Penstock Assessments

Structural Integrity has assessed over 45,000 feet of steel penstocks for various clients.  We have experience in evaluation of degradation mechanisms, development of acceptance criteria, determination of assessment methodologies, inspection equipment & techniques, and flaw evaluation.  We know where and how to look for degradation, as well as how to determine degradation rates.

Penstock failures can be catastrophic.  Proper identification of all the degradation mechanisms is critical.  Overlooking or under-estimating a degradation mechanism can lead to unexpected failures.  Understanding the degradation mechanism aids in better identifying key assessment regions and assessment methodologies. Our talented people, using the latest technology and methods, deliver unmatched value, actionable information, and engineering knowledge for the management of your most critical assets. We provide the following NDE services for our hydro customers:
