Horizontal tank strength analysis considering nozzle loads and horizontal deviations

Abstract

When assessing the reliable and safe operation of technological equipment, and in particular, capacitive-type equipment, a fairly diverse number of methods are used. However, all current procedures do not sufficiently take into account the impact of certain factors on the forming stressed-deformed state of the object. Usually, when assessing the actual technical condition of an object, the level of defect of the object is determined, and appropriate calculations are carried out according to the criterion of the dominant damage mechanism. A significant impact on the stressed-deformed state of the shell structure can be exerted by the level of loads on process nozzles from the connection of process pipelines, as well as possible deviations during installation work. One of these deviations may be a deviation from the horizontal of the housing when installing supports on the foundation. Moreover, the combination of the action of the above factors can have a determining negative effect on the strength, and, accordingly, the operational reliability of the technical device. In the modern world, technological progress does not stand still and the consequence of this is the development of a fairly extensive number of software products that allow you to simulate possible individual scenarios for the development of unfavorable processes and predict the behavior of the object under the conditions under consideration. In this work, studies are carried out on the strength analysis of the horizontal tank, taking into account various values of loads on the nozzle of the body diameter, as well as taking into account the deviation of the tank body from horizontal.
