Abstract:

The overall objective this research program was to enhance detection and sizing accuracy of crack-like and planar imperfections created during pipeline fabrication and service using matrix phased array (MPA) ultrasonics tools with the goal of improving the predicted reliability of pipelines during early design stage and service life. The technical objectives of the program were to: develop concepts for MPA ultrasonic probe modules for outside diameter (OD) or inside diameter (ID) pipe inspection; define and optimize detection and sizing capabilities of the MPA modules via modeling and simulation; design and fabricate two probes modules (one for OD and one for ID inspection); and to determine and demonstrate the detection and sizing performance of the MPA probe modules. The following four MPA probe concepts were developed:
