摘要：
Acoustic emission tests are highly relevant among nondestructive tests applied to equipment in the petroleum industry. This paper presents methodologies for the classification of acoustic emission patterns obtained in testing to identify the propagation of discontinuities in pressurized tribes. This work is a continuation of previous research. To estimate the accuracy of tire classification and give greater reliability to previous results, rise is made in this paper of new signals with a greater number of parameters, and some new methodologies not used in previous work are presented here. The new results show tire efficiency of the pattern classification techniques implemented.
