“…Yet the results showed great improvement when compared to the work of Reber [6], which detected the pits of at least 10 in diameter, or 20 when is desired the measure the pit depth, and also the work of Okamoto [7], which detected pits of 10 diameter with 1 depth, against the pits of 3 in diameter detected in this work. Finally, it is worth mentioning that the results achieved by the author in earlier studies [8] using a threshold detection, or even the peak detection, showed larger errors in the detection of the first wall, where neither visually was possible to see a good correlation between the results of the ultrasonic inspection and the tridimensional measurement.…”

This work describes the development of an algorithm that uses ultrasound to evaluate the degree of corrosion in pipeline walls. The developed algorithm was implemented in a dedicated digital circuit that can be embedded in ultrasonic pigs for pipeline corrosion inspection. The algorithm is based on the mathematic model known as matched filter. It also incorporates a peak detection method for the localization of ultrasound echoes, originated from the signal reflections in the pipeline walls. One of the problems is the determination of the signal (and filter) that should be used, but using a signal design approach, a large number of possibilities could be analyzed so that only a few had to be tested in experiments. Finally, the best signals were used to inspect a sample made of a corroded pipeline section, and the results were analyzed. The detection of the first wall showed promising results when compared to the results of a tridimensional inspection of the same walls. It was possible to reconstruct the profile of the internal wall with good likelihood, even in badly corroded areas. The detection of the second wall showed some satisfactory results on low corrosion levels, but showed some problems with high corrosion levels, compromising the direct measurement of the pipeline wall thickness.

“…As conventional MFL (Magnetic Flux Leakage) is universally used in the industry and qualitatively known to be sensitive to volumetric metal loss [4][5][6], ultrasonic crack detection is a superior method for cracks and crack-like defects, because it is more sensitive to defect edges that are close to each other [7][8][9][10]. The objective of this test was to evaluate and quantify the performance for UltraScan The electronics vehicle contains the ultrasound instrumentation units.…”

Globally, more and more attention has been paid to the integrity of Girth Welds (GW) of oil and gas pipelines due to their failures with high consequences. A primary concern is that defects originate during field construction but over time may be subject to external loads due to earth movement. GW defects in newly built pipelines are also assumed to exist but would be much smaller in size, and more difficult to detect, which motivated the investigation into minimum defect detection capabilities of the inspection technologies. This study presents the evaluation results of UltraScan™ Circumferential Crack-Like Detection (USCCD) technology for oil pipeline GW inspection, based upon the pull test and in field data from Inline Inspection (ILI) of pipeline by PetroChina Pipeline Company (PPC) using GE PII (General Electric Company, Pipeline Integrity Inspection) 32" UltraScan™ CCD Tool. The performance of USCCD is given according to the ILI data, pull test results and dig NDE (Non-Destructive Examination). It can be concluded that crack-like defects with clear edges can be detected during ultrasonic propagation; however, the irregular shape of weld makes the inspection more difficult. It is still a challenge to identify the type of defects, and depth sizing can only be classified not quantified, which would require more excavations. However, this technology is feasible for the alternative technology of GW defect inspection.

“…However, because of some practical limitation, such techniques are not efficient for detecting micro cracks in welded parts. Reber et al [ 8 ] have shown an ultrasonic configuration for crack detection in carbon steel pipeline girth welds, and presented relevant experimental results demonstrating the technique capability. Nevertheless, the authors highlighted, in their conclusions, that the application of such a technique in in-line inspection tools is still a challenge.…”

Eddy current transducer with sensing coils placed orthogonally and connected in differential mode was introduced to evaluate fatigue cracks in clad pipeline circumferential welds. A dedicated embedded electronic hardware was developed to drive the transducer and measure the electrical complex impedance of the coils, and was specifically designed for operation under autonomous in-line inspection tool. In the laboratory experiments, an automated inspection was performed with the goal to evaluate transducer’s detectability, and different scanning speed was tested to reproduce in service situation. The results have confirmed that the introduced eddy current transducer is a potential solution for fatigue crack detection in clad circumferential weld root, while the hardware developed presented a reasonable SNR reaching the data rate required to be incorporated in an autonomous in-line inspection tool.
