Abstract: In the present paper some results are shown in the application of advanced ultrasonic techniques, on two different industrial systems. These applications are the inspection of several kilometers of pipes of different diameters and the inspection of a liquefied gas storage sphere. The techniques used were Phased Arrays (PA), Time of Flight Diffraction (TOFD) and Guided Waves (GW). The strategies were established and specific procedures were generated for each case. In the present work we explained in a general way what they consisted. In the particular case where the guided wave technique was applied, a strategy was developed that complied with all the established documents despite the fact that not much information was available, especially regarding the methodology to be followed once different types of anomalies with different level of importance were detected.

Keywords: Tofd (39), ultrasonic guided waves (30), storage sphere inspection, ultrasonic phased array technique,
