The author of the article consider the issues of designing a distribution network for incoming crude oil to separate oil refineries that have their own pipelines for transporting oil from the terminal, the throughput of which corresponds to the production capacities of these enterprises located at different distances from the terminal. It is assumed that pipe diagnostics will be performed based on the presence of a leak using the negative pressure wave method. It is determined that the problem of optimal distribution of crude oil coming to the terminal by the cluster of oil refineries should be solved separately, taking into account the following conditions: one or several types of oil come from the terminal (the specific heat capacity of crude oil C is different); the pipelines of these enterprises differ in diameter D and distance x to the terminal. Three problems of optimization of pairwise connections among the showings of the triad elements (C, D, x) are formulated and solved, which made it possible to determine those undesirable connections of the selected elements of the pairs, at which the oil in the pipelines can be cooled maximally. A significant change of temperature, in turn, causes unacceptable changes of speed of negative pressure wave propagation. As a result, the error of locating leaks using the negative pressure wave method can reach an unacceptable level.
