Pipeline systems are used in almost all industries and are rightfully considered one of the safest and most economical ways of transporting various media. Nevertheless, the consequences of failure and violating the integrity of this class of equipment lead to significant technological disasters. Pipeline valves are integral elements of pipeline systems, including those responsible for operational safety. To confirm the main characteristics, such as strength and tightness, pipeline valves must pass a set of tests. However, the problem of equipping production facilities with test equipment is relevant now because a significant part of the equipment fleet no longer fully complies with current operating conditions. Therefore, this study develops equipment for in-plant pneumatic testing of swing check valves for pipeline systems of hazardous production facilities with ultra-high parameters of the working media. Keywords —finite-element method, mathematical simulation, pipeline system, pipeline valves, pneumatic testing, strength analysis, stress-strain state, swing check valve, technological hydraulic installation

Accidents on gas pipelines cause significant damage to the national economy and the economy of the state. Thus, it is necessary to always be prepared for such situations in order to restore the normal operation of the gas pipeline as soon as possible. An important role is played by the execution time of the control actions to localize the accident, pump out the gas, and change the operating modes. It is essential that such control be undertaken, especially if such a situation occurs near a gas-measuring installation for measuring the amount of vented gas. Therefore, the control actions must be error-free in order to quickly stop the non-stationary process, which can lead to undesirable consequences. The paper presents a mathematical model of the operation of the pipeline, developed for the management of the pipeline in an emergency. The analysis of the problem of the occurrence of accidents was carried out, and the effect of liquid on its walls was modeled when the operating mode of the pipeline changed. An example is presented using a numerical model carried out in ANSYS, as well as being analyzed analytically. The results of the calculations are presented, and special attention is paid to the parameters influencing the change in the operating mode of the pipeline.
