In order to evaluate the actual technical condition of existing main and technological pipelines, cylindrical – rotating objects, the issue of technical resource evaluation is considered taking into account the life of the objects, them odes of action on them of force \u00a0actors of different nature, which cause changes in the bearing capacity of the objects. In doing so,\u00a0\u00a0 statistical approaches that provide additional information about the loading of the investigated object, the presence of periodic loads are used. For this purpose, the components that characterize the change in stresses of the deformed state are studied. To determine the structures durability, it is necessary to determine whether the law of change of stresses obeys the normal law of distribution. This selects those sectors on a cylindrical object where the stress change is maximum. It is potentially possible to control the process of changing voltages a teach point in the grid, but in this case there is a need to deal with large amounts of computation. A calculation scheme is proposed for estimating the durability of technological rotating objects using a statistical criterion, as well as a method for determining the change in the stress-strain state of these objects. The method of testing the hypothesis about the normal law of distribution of random value \u2013 change of the stress state of the object of study is implemented. The directions of further researches are determined, which should include determination of physical and mechanical characteristics of material of technological pipelines; determination of statistical characteristics of modes of vibration or change of loads; implementation of known methods of measuring the displacement of surface points for the purpose of the law of motion; experimental and theoretical determination of the unknown characteristics of the materials from which the elements of the design of technological rotary objects are made.
