Mechanical Properties and Fracture Analysis of a Plant Oil Storage Tank Accident

Article Preview

Abstract:

The collapse mechanism of plant oil storage tank was discussed in the paper. Observation made on the site indicated that No. 804 tank collapsed with disintegration. The incomplete penetration area was found by weld macro analysis. Stress intensity factor of crack in the tank which is calculated using the classical theory showed that the main reason for the accident was not the incomplete penetration weld. The hexane vapor explosion is presumably the dominant factor leading to the accident by calculation and analysis. The count measures are also proposed to prevent the similar accidents.
