“…the results obtained in the study are in good agreement with the works [23][24][25]. Similar mechanisms of fatigue and corrosion-fatigue fracture are observed in tubular steels of such chemical composition [26][27][28][29][30] under difficult operating conditions [31][32]. It can be concluded that the detection of the boundaries of the perlite plates became possible only because of the influence of the aggressive components of the investigated media for the reason that such destruction was not observed in the air.…”

The processes of corrosion-fatigue failure of materials in contact with mineral fertilizers are insufficiently studied. As a result of joint influence of atmospheric corrosion and mechanical loads, about 70 to 80 % of machine parts get out of order, 20 to 25 % of which are failures caused by operating overload due to the strength loss because of atmospheric corrosion. A large part of metal structures of agricultural vehicles used to transport mineral fertilizers is under the direct influence of aggressive environments and dynamic loads that occur during the motion by field roads. Saturated solutions of the most aggressive working environments used in agricultural production, in particular ammonium sulphate and nitrophosphate are investigated to reduce fatigue resistance of ordinary steels groups – St3 and St5 and quality steels – 10 Steel, 15 Steel, 20 Steel, 25 Steel when loaded at all levels. The fatigue endurance limit decreases in comparison with air up to 2.02 times in a solution of ammonium sulphate, and to 2.32 times in a solution of nitrophosphate. In organic fertilizer environments, compared to distilled water, the conditional fatigue endurance limit increased to 9 %. The properties of the given materials as an inhibitor of corrosion-fatigue failure were discovered and proved.

“…The steady-state equations are generally contained in the non steady-state equations and can be obtained by zeroing all the derivatives in time. The main advantage of experimental research is the elimination of sources of errors related to the lack of a priori information when drawing up an analytical model of the elements of the gas supply system [8,9,12,17,19]. However, the possibilities of the experimental methods are limited by the narrow range of initial data and, most importantly, the practical impossibility in some cases of reproduction of the results of the experiment in operational conditions or close to them due to the big economic losses or the duration of the experiment.…”

“…On the other hand, gas losses associated with technological transportation costs are increasing, in particular, caused by the unsteady flow of gas and frequent changes in the modes of operation of the gas transmission network [22,23]. Іt is known that losses from gas shortages to consumers far outweigh the losses associated with technological costs of gas transportation [6,8,9,16,17]. Therefore, the problem of choosing the optimal ratio between the cost and reliability of gas pumping is considered here.…”

In the period of shortage of gas supply, special attention is given to reducing the supply of gas to its consumers, that is, their complete and uninterrupted gas supply. Increasing gas losses associated with technological transportation costs, in particular caused by gas flow instability and frequent changes in gas transmission network operating modes. Considering losses due to unreliability of gas pumping is one of the important tasks of gas supply optimization. The purpose of the study is to develop an optimization mathematical model that will simultaneously take into account the factors of reliability and minimum lossesIn the general case, the optimization calculations of the modes of operation of the main gas pipelines are intended to solve three main problems: determining the maximum productivity, calculating the optimal mode with a given productivity and choosing the optimal strategy, the development of the pipeline. On the basis of approaches of simulation modeling of complex systems, a multi-parameter mathematical model of gas supply process optimization was developed. It is shown that a comparative analysis of the forecast and actual indicators of the operating modes of the plunger gas pumping unit shows their satisfactory convergence. The performance of the compressor operation period in the process of injection according to the forecast deviates from the actual value for the whole period of operation of the plunger gas pumping unit in 2016 by 2.98%. The optimization problem of gas pumping planning is considered, taking into account the expected losses, on the basis of which the transfer of the controlled system from the initial state to the final one is carried out by such a sequence of states that minimizes the total cost of the system evolution.

“…[4] Moreover, the accumulation of liquid contaminants within the internal cavities of gas pipelines can lead to erosive wear of fittings [5], internal corrosion processes, that prolonged operation reduces the parameters of resistance to fatigue and prolonged static loading in corrosive environments [6]. Corrosion processes are accompanied by significant losses of the transported product [7]. During the autumn-winter period, the presence of liquid in the gas causes the formation of hydrates.…”

Experimental setups using steel and transparent glass pipes, along with equally spaced steel stamped and transparent plastic tees, were designed for testing. The experimental results provided insights into the influence of flow directions, pig length, material properties, and air consumption on the dynamics and strength of the pigs within the tees. Furthermore, the study identified the causes of temporary halting, jamming, and the mechanisms of damage to cylindrical pigs made of hyperelastic materials within pipeline tees.
