ABSTRACT
In recent years, there has been a tendency to increase the share of high-viscosity and high-setting oils in the total volume of oil production in Russia. Pumping such oil through main oil pipelines creates certain difficulties. One of the ways to transport oils with abnormal properties is to pump them in a mixture. The article considers the development of a mathematical model for the rational mixing of oils with abnormal properties. The mathematical model allows you to determine the required concentration of high-viscosity oil, which will provide a preset viscosity value of the mixed flow to ensure effective pumping modes, and also allows the formation of a mixture with a preset density value for supply to consumers.
KEYWORDS: high-viscosity oil, viscous oil, modified Walter equation, compounding system, variable frequency drive.

Water is often present in oil and oil products due to poor preparation or incomplete removal of water after hydrotesting. Due to its higher density, water accumulates at the lower points of the pipeline section. One of the most difficult parts in this context are vertical 90-degree bends, where the flow direction changes to vertical, which is the limiting case of the problem considered. However, a separate analysis of bends from vertical sections is important for the following reasons: these connecting parts of pipelines are subjected to increased loads and, if the product is not completely cleaned, are also exposed to mechanical particles due to centrifugal forces. Together, these factors cause accelerated corrosion processes and, as a result, a high risk of emergency situations. The presence of water accumulation not only affects the complex mechanism of corrosion processes, but also significantly increases the hydraulic resistance of the system due to local constriction of the pipeline cross-section. In the work, the modelling of the processes of water accumulation removal from the vertically oriented 90-degree outlet is completed using the methods of computational hydrodynamics in the ANSYS Fluent software package, and the results are processed using the methods of mathematical statistics in the Statistica software. On the basis of the data from the computational experiments, the critical equation describing the dependence of the critical velocity on the dimensionless Bond and Archimedes numbers was obtained.

ABSTRACT
This paper presents the rationale for transitioning from traditional linear field main oil pipelines to networked pipeline structures capable of ensuring functional redundancy under modern combat conditions characterized by the use of precision-guided weapons capable of destroying critical fuel supply infrastructure deep in the rear. The use of linear pipeline systems entails strategic risks, as damage to a single section can paralyze the entire fuel supply system, a fact confirmed by recent military conflicts. Alternative delivery methods, such as road or air transport, lack the required throughput capacity and are themselves vulnerable to enemy attacks. As a solution, the authors propose a networked pipeline architecture similar to the internet, featuring multiple nodes, closed loops, and alternative (redundant) routes that allow rerouting of fuel flow in case of damage. To further enhance reliability, the paper suggests using field fuel depots with elastic (soft) tanks for temporary fuel storage during pipeline repairs. The key advantage of the proposed concept is high survivability (resilience): the system maintains functionality even under multiple damages. The paper provides an assessment of improved pipeline system survivability through network-based functional redundancy. Although networked structures require higher capital investment due to increased total pipeline length, the authors prioritize survivability over cost, drawing a historical analogy with the adoption of automatic weapons. Networked redundancy transforms a vulnerable «artery» into an adaptive «capillary system», which is essential for ensuring uninterrupted fuel supply and maintaining the combat readiness of Armed Forces in future warfare.
KEYWORDS: field main pipeline, functional redundancy, pipeline system resilience, petroleum supply; pipeline network.

ABSTRACT
The study of the movement of real liquid and gas through pipes is of direct importance for the design of gas and oil pipelines and other hydraulic structures. Mathematical modeling of unsteady movement of liquid and gas in pipelines is also necessary for solving problems that arise during their operation. The high pressure at which oil and gas pipelines operate is the main force factor affecting the linear part of the transport system. The purpose of this work is to study the unsteady pressure in a gas pipeline having sampling points in a given section. Based on the work of I. A. Charnyy and using the Heaviside function, the problem is formulated as a single partial differential equation and solved under boundary conditions of the first kind using the sine Fourier transform method. Working formulas of pressure dynamics are obtained for both unstable (unsteady) and stationary periods. Special cases are formulas for a simple section of the pipeline, i.e. in the absence of transit sampling.
KEYWORDS: gas pipeline, non-stationary mode, Heaviside function, Fourier transform, sampling.

ABSTRACT
Gas condensate is one of the most valuable resources for the oil refining industry. It could be obtained when processing natural and hydrocarbon gas for pipeline transportation. The paper proposed to consider the possibility of adapting a vortex tube as an additional source of cold at the intermediate separation stage, whichmay increase the efficiency of the throttling valve when used together. The paper considered the formation of a modern and most realistic concept of vortex interaction proposed by A.P. Merkulov in 1964. In addition, various design elements were analized for vortex tubes that were used in experimental studies of the process. The paper illustrates the vortex tube model created in the ANSYS Fluent that were validated with the existing open-access results of experimental studies of the vortex tube design. Based on the results of the numerical model the potential for using a vortex tube as a process element at the intermediate separation stage is shown.

ABSTRACT
When detecting leaks in main pipelines using the pressure drop wave method, it is necessary to distinguish between external and internal waves, determine their velocities and coordinates of sources. The article suggests ways to solve these three problems. It is based on the synchronization of pressures on neighboring sensors by taking into account the pressure drop in the area and the pressure shift during the wave travel between the sensors. The application is shown in the modes of the main oil pipeline with real sampling.
KEYWORDS: oil pipeline leak detection system, pressure drop wave, amplitude-phase synchronization method, wave speed estimation, external waves, leak localization.

ABSTRACT
Main gas pipelines laid in the ground are exposed to various loads. In addition, pipelines are affected by soil corrosion. Defects in the process of operation of pipelines are identified during the in-pipe diagnostics. The article presents the results of studies of the stress-strain state of the sections of elastic-plastic bending of pipelines, which showed that the longitudinal and bending stresses are close in value, which indicates that the temperature stresses are mainly transformed into bending radii. It has been established that the bending stresses, which are based on the bending radii determined according to in-pipe diagnostics (VTD) data, can serve as a criterion for assessing the stress-strain state of main gas pipelines in areas of elastic-plastic bending. It has been proposed that gas transportation companies maintain the minimum temperature of the transported gas to ensure the required bending stresses.
KEYWORDS: main gas pipeline, operability, in-pipe technical diagnostics, elastic-plastic bending, pipeline fixation.

ABSTRACT
The work is devoted to the development of a methodology for assessing the performance of tanks of the RVS type with butt welded joints with edge displacement. V-shaped stress concentrator is formed in butt welded joint with displacement of edges. To assess the danger of this defect, there are calculation formulas and criteria based on fracture mechanics. In a symmetrical plane stress state, the load of the «normal separation» type has a significant contribution. Formula for calculation of coefficient K1 at load of «normal separation» type is proposed. Tensile tests were carried out on flat samples made of 09G2S steel to determine the limiting coefficient of stress intensity.
KEYWORDS: tank, defect, edge displacement, stresses, welded joint, stress intensity factor, strength.

ABSTRACT
Away for improving the accuracy of leak location detection in oil pipelines using the Negative Pressure Wave (NPW) method is considered. It is taken into account that during the transportation of crude oil with a high paraffin content, paraffin deposits form on the inner walls of the pipeline when the oil cools below a certain temperature, which negatively affects the functional performance of the oil transportation system. It is shown that heating the pipeline can also be used to reduce the temperature error of the NPW method. An optimization problem is formulated and solved for continuous external pipeline heating using the method of direct electric heating. It is demonstrated that with decreasing external wall temperature T0, the newly introduced function x(T0) must also decrease. That is, during heating, lower temperatures on the external surface of the pipeline should be provided at the beginning of the route, and higher ones at the end. This heating sequence can reduce the temperature-related error of the NPW method used for leak detection in pipelines.
KEYWORDS: negative pressure wave method, optimization, pipeline, direct electric heating, oil transportation, temperature error.

ABSTRACT
Operational monitoring of residual mechanical stresses is a pressing issue during the construction and operation of vertical steel oil storage tanks.In this case, the choice of the control method should be based on reliable data. Among non-destructive methods, the magnetoanisotropic control method is widely used, among destructive methods – the hole method. Destructive methods provide a quantitative assessment of the stress state, but are associated with mandatory destruction. Non-destructive methods are considered indirect and therefore inaccurate. However, these methods do not require destruction of the structure and provide operational data on stresses, which is especially important in reservoir engineering. The purpose of this work is a comparative analysis of stresses obtained by destructive (hole method) and non-destructive (magnetoanisotropic method) methods.
KEYWORDS: residual stresses, magnetoanisotropic method, destructive testing, hole method, difference in principal mechanical stresses, stress-strain state, non-destructive testing, testing methods
