Inspection Case and Its Failure Cause Analysis of Leaked Storage Tank

Abstract

Leakage is a frequently occurred failure mode during the operation of atmospheric storage tanks with large probability of occurrence. According to different design and operation conditions, there are various different causes for the leakage of storage tank. The inspection of a storage tank of certain chemical enterprise before and after leakage is discussed in this paper. Before, the change in operation condition during this period is also introduced and the leakage cause of the storage tank is analyzed. The analysis result shows that related suggestions for leakage inspection of storage tank and preventing leakage accidents to provide guidance for the safe operation of atmospheric storage tank.
