During the last years, PETROBRAS has trying to use acoustic emission technique as a inspection tool. In
this period, acoustic emission concept was changed from a revolutionary technique to a global inspection
technique with the aim of indicate areas to complimentary inspection.
In the last years more than 600 acoustic emission exams was done in equipments like pressure vessels,
reactors, tanks, spheres and etc. In 2002 the results of acoustic emission exams and nondestructive tests done
in this equipments was collected to build a database of PETROBRAS environment.
This paper shows the analysis done to obtain a relationship between acoustic emission and life assessment of
industrial equipments.
