Analysis and Experimental Study on Acoustic Emission Source Characteristics of Corrosion Process in Atmospheric Vertical Tank Bottom

摘要

The mechanism of acoustic emission signal from the corrosion in atmosphere vertical storage tank bottom was introduced; and the attenuation law of broken lead's acoustic emission signal within tank water was discussed, including the range of characteristic parameter values of corrosion acoustic emission signals from different mediums and the corrosion regulation, as well as the signal waveform characteristics received by the sensors in the water at different corrosion stages, this provides evidence to corrosion evaluation of the atmosphere vertical tanks.
