Problems from the View Point of Corrosion Control on Troubles Caused by Localized Corrosion

Abstract

Analysis of localized corrosion failures shows that troubles caused by materials, design and fabrication are a few, while those caused by operation occurr freqently over 50% of the total failures. Some of them probably develop social anxiety and may cause serious disaster such as explosion, fires and death. In this report, a yearly change of number of failures in complex up to 1988 is analyzed and problems associated with the troubles caused by localized corrosion are discussed from the viewpoint of corrosion control.
