CORROSION FAILURE ANALYSIS OF OIL TANKS BY MEANS OF FAULT TREE ANALYSIS
原油储罐腐蚀机理及致因事故树分析

Corrosion failure of tanks was analyzed in this paper using Fault Tree Analysis.Fault Tree was set up based on two corrosion types:internal corrosion and exterior corrosion.Then 30 minimal cut sets of tank corrosion were gained by qualitative analysis of the fault tree.Correspondingly protective measures including use of antistatic coating,cathodic protection combined with coating,thermal spraying aluminum technology,and adding corrosion inhibitor are adopted to improve the security of tanks according to analysis results.
