Overloading Effect on the Carrying Capacity of Cylindrical Tank with Torispherical Heads for the Underground Storage of Petrol

Horizontal cylindrical double skin steel tank with torispherical heads for the underground storage of petrol has been manufactured in the workshop (diameter of the vessel was 2, 5 m and the shell thickness 6 mm). Before exploitation it has to be tested with pressure of 2 bars according EN 12285-1 norm. During the pressurization uncontrolled pressure increasing happens. Effects on this overloading have been analysed by using of finite element method. It is numerically proven that plastic collapse of internal head occurred in range between 5 and 6 bars.
