Pulsed Eddy Current (PEC) has been successfully deployed over the last decades for a variety of corrosionrelated applications, most notably for Corrosion Under Insulation (CUI) inspections, Corrosion Under Fireproofing (CUF) and Flow Accelerated Corrosion (FAC). This technology has proven to be an efficient inspection tool, allowing for the detection of corrosion without having to remove coating or insulating material over typical pipes, tanks and vessels. Despite the success of the technique, one limitation of the conventional PEC systems is that achievable productivity is relatively low, especially on thick walls and when an inspection with high spatial resolution is required. Recently, we developed a Pulsed Eddy Current Array (PECA) solution which greatly increase the productivity of the technique. The system is based on a novel pulsed eddy current probe featuring a linear array topology. The proposed probe design offers 46 cm of coverage in one single pass, improving the productivity of a pulsed eddy current inspection by a factor 4 to 10 compared to non-array solutions. The probe can be used on flat and curved surfaces with a diameter down to 15 cm. This is made possible by the non-rigid mechanical design of the probe, so that its main axis can be wrapped around a pipe or otherwise bent to follow the curvature of the inspected surface. Proper analysis of the array raw data requires an adapted analysis algorithm, whose sizing performance on insulated components is presented in this paper along with examples of defect sizing maps of a typical insulated pipe. After more than a half year on the market, significant field experience has been gathered with this technology making it now possible to show results acquired on real-life components. Some of these will be presented, analyzed and discussed. The sizing and productivity performance of the latest improvements of PEC technique are compared to prior art technology, and benefits are discussed.

Detection of Trans-Granular Stress Corrosion Cracking in Complex Line Geometry using Eddy Current Array s. Parmentier1 3, O. Marcotte2 3 1Eddyfi 57, Quebec, Canada 2Nucleom inc. 7, Québec, Canada
Close
Trans-granular stress corrosion cracking (TGSCC) commonly affects nuclear infrastructure integrity due to the chemically induced stress into material surfaces. Although eddy current testing has been successfully used to detect such flaws in non-ferromagnetic material, the complex geometry of a vent line in a hard-to-reach area prevented inspection until now. The need to inspect a 50 mm, 4 mm wall thickness 304 stainless steel vent line in a North American nuclear power plant represented a challenge due to the complex geometry caused by several tight 1.5D, 90° bends, the presence of circumferential welds, a radioactive environment, the deployment in a hard-to-reach location and the aim of full volumetric inspection, thus calling for the best of modern multiplexed eddy current array technique combined to a clever and adaptive mechanical probe design. This paper presents the application of an eddy current array sensor offering full coverage over 360° and sensitivity to both axial and circumferential TGSCC, and unveils the custom collapsible and flexible probe design developed to comply with complex line geometry and to sustain eddy current array (ECA) performance. Numerous tests were conducted as part of the technique qualification process on a line replica including TGCSS inserts and results showed adequate detection of 0.4 mm deep TGSCC in the straight sections and 1 mm deep in the bends.

Pulsed Eddy Current (PEC) has been successfully deployed over the last decades for a variety of corrosion-related applications, most notably for Corrosion Under Insulation (CUI) inspections, Corrosion Under Fireproofing (CUF) and Flow Accelerated Corrosion (FAC).
This technology has proven to be an efficient screening tool, allowing for detection of corrosion without having to remove coating or insulating material over typical pipes, tanks and vessels. However, the use of this technique has been severely limited for components wrapped in galvanized steel weather jacket, which abound in some geographic markets.
This paper discusses the challenges of working with galvanized steel as well as some of the solutions that allow quality PEC inspection of such components. We present the most recent improvements in PEC technology, that greatly enhance signal quality and defect sizing accuracy when measuring through ferromagnetic weather jacket materials. Laboratory and field results will be presented and analyzed. We present a clear picture of the possibilities and limitations of the current technology, and key improvements over conventional PEC techniques are discussed.

Recent advances in Pulsed Eddy Current signals analysis for compensation of mass effects V. Demers-Carpentier 6 Eddyfi 57, Quebec, Canada
Close
Pulsed Eddy Current (PEC) has been successfully deployed over the last decades for a variety of corrosion-related applications, most notably for Corrosion Under Insulation (CUI) inspections, Corrosion Under Fireproofing (CUF) and Flow Accelerated Corrosion (FAC). This technology has proven to be an efficient screening tool, allowing for detection of corrosion without having to remove coating or insulating material over typical pipes and tanks.
Conventional PEC signal analysis has known limitations: defects smaller than the sensing area of a PEC probe are typically undersized. Also, conventional PEC techniques cannot be applied reliably in the critical pipe regions surrounding flanges, joints, supports, nozzles, valves, etc. Unfortunately, on insulated pipes and tubes, corrosion is often found near flanges, joints and valves where insulation waterproofing is more difficult. The mass effect associated to these metallic elements is well known to affect the PEC signals and to impair the detection of defects.
In this communication, we will present the latest advances in the modeling and analysis of the PEC signal, showing improvements in repeatability and accuracy. In particular, we present a novel PEC signal analysis algorithm that largely improves the sizing of small defects. A further improvement of the same technique extends the applicability of PEC to CUI/CUI inspection of pipe regions surrounding flanges and other metallic masses. Laboratory results of tests conducted on carbon steel reference specimens are presented. The performance of these improved PEC analysis techniques is compared to prior art technology, and key benefits are discussed.

Near Field Array for Complete Inspection of Ferromagnetic Stainless Steel Tubing J. Renaud 6 Eddyfi 57, Quebec, Canada
Close
Eddy current inspection of ferritic/ferromagnetic stainless steels such as 400 series stainless, Seacure and Monel has always been challenging. The typical inspection method used for these materials has been full saturation eddy current where powerful and carefully arranged magnet assemblies magnetically saturate the tube wall allowing the eddy current to flow as though the material were non ferromagnetic. In addition to mechanical challenges associated with magnet probes, full saturation eddy current is effectively blind below ferromagnetic support structures.
A new eddy current technique has been developed that does not require the use of magnets. Near field array for ferritic/ferromagnetic stainless steel (NFA FS) is an ET array solution for thorough inspection of thin walled ferritic/mildly ferromagnetic tubing capable of detecting and characterizing ID and OD defects both in the freespan and below ferromagnetic structures. The NFA FS contains no magnets and uses near field eddy current (a combination of field and eddy current). This paper will review the operating principles of the probe and present laboratory and field experiences from the last two years.

Heat Exchanger Tubing: Extending The Reach Of IRIS Inspections O. Lavoie Eddyfi 57, Quebec, Canada
Close
The internal rotary inspection system (IRIS) is a UT technique commonly used to inspect a wide range of ferrous and non-ferrous tubing materials in heat exchangers. The technique has proven efficient and reliable in detecting and sizing general wall loss and localized corrosion from the inside (ID) and outside (OD) diameters. IRIS is the most popular inspection technique worldwide for its sizing capability. The most common IRIS systems are, however, only suitable for the typical 1.0 in (25.4 mm) and 0.750 in (19.05 mm) tubing and offer a relatively low pulling speed.
This paper discusses the development and the extension of IRIS technology, including laboratory and field-testing results on typical heat exchanger tubing.
A micro turbine, combined with a dedicated centering device equipped with spring-loaded arms, offers a unique alternative when inspecting small diameter tubes 0.500 in (12.7 mm) at faster pulling speeds. This new centering device concept is highly durable and offers straight C-scan imaging results, which are easier to analyze than conventional IRIS imaging results. At the other end of the spectrum, extra-large centering devices support tube diameters ranging from 3.0 in to 6.6 in (76.22mm to 167.64 mm) at reasonable pulling speeds.
To further extend the applicability of IRIS, a custom single-part flexible turbine and centering device now allows users to easily manage tube bends and elbows by increasing the bend areas inspection zone that can be scanned in a single pass.
The development of these new advances in IRIS technology proved to be challenging, but results in a wider range of applications for the IRIS technique for the industry.

2017-08 Cofrend 2017 Méthodes alternatives à la magnetoscopie et au ressuage Courants de Foucault Multiéléments : Une alternative aux méthodes conventionnelles de contrôle non destructif de surface A. Raude 4, H. Lemieux 2, M. Sirois 3 Eddyfi 57, Quebec, Canada Méthodes alternatives à la magnetoscopie et au ressuage
Close
Un grand nombre de techniques non destructives (CND) ont été mises au point et utilisées avec succès au cours des dernières décennies sur divers matériaux, notamment pour la détection de défauts surfaciques tels que : fissures, piqûres, corrosion, etc. Celles-ci sont plus ou moins sophistiquées, mais fournissent toutes des informations précieuses sur l'intégrité des structures inspectées, et présentent des avantages et des limites qui leurs sont propres.
Des méthodes établies telles que le ressuage et la magnétoscopie sont efficaces, mais peuvent manquer de praticité dans certaines applications. D'autres, comme les courants de Foucault conventionnels (CF), déploient principalement des sondes mono-élément, impliquant des temps d'inspection importants. Les résultats obtenus grâce à ces techniques sont aussi dépendantes des compétences de l'opérateur, des propriétés des matériaux et de la géométrie des structures inspectées.
Les avancées de l'électronique ont permis le développement de techniques d'inspection plus modernes telles que les courants de Foucault multiéléments (CFM), ce qui permet d’augmenter la fiabilité et la répétabilité des inspections de surface par rapport aux méthodes plus traditionnelles. En effet, la possibilité d'adapter les configurations de bobines et les modèles de séquençage permet aux utilisateurs d'optimiser la chaîne d'acquisition à leur application. De plus, en multipliant les éléments actifs et en exploitant les capacités avancées de traitement de données, les solutions CFM permettent d'effectuer des inspections plus rapidement, souvent avec moins de préparation de surface. Ils offrent également des avantages supplémentaires tels que l'imagerie de type cartographie (par exemple, les affichages C-Scan 2D et 3D), une meilleure couverture de surface, une facilité de déploiement et l'archivage des données. Enfin, en plus de la détection des défauts, la technologie CFM peut également parfois fournir un dimensionnement quantitatif.
Cet article décrit la méthode par courants de Foucault multiéléments ainsi que ses variations, y compris ses avantages et limites. Le déploiement des CFM sur des structures soumises à des conditions environnementales représentatives, est également discuté. Des applications typiques sont présentées, fournissant des informations précieuses sur l'utilisation de cette technique en remplacement de techniques plus classiques.
