Effect of temperature fields and bottom sediments of oil products on the stress-strain state of the design of a vertical steel tank
Tanks for storing oil and oil products during operation are exposed to a combination of external, static, low-cycle, temperature, snow and wind loads, bottom sediments, etc., which leads to a decrease in operational reliability and a decrease in the durability of tank structures. Numerical modeling methods, in contrast to standard methods for calculating strength and stability, allow us to create an adequate finite element model at the stage of development of a geometric model. This article describes the analysis of the stress-strain state of the tank taking into account bottom sediments of oil products and the influence of the temperature of the oil product and the environment using the Ansys software package. Based on the analysis of the stress-strain state using finite element modeling on the example of a vertical steel tank, it was shown that the stresses in the zone of the miter weld, as well as in the places of installation of the receiving-distributing branch pipe and the manhole, are maximum. It is in these zones that the influence of bottom sediment and temperature is significant, since they form local elevated stress zones, which increase significantly when the walls are thinned.
