This paper demonstrates the problem of calculating a rational piezometric pressure distribution graph in high-and medium-pressure gas distribution networks. These issues are particularly relevant in the design of gas distribution networks. In addition to the often used in practice design opportunities to reduce the cost of building gas distribution networks, rational choice of the optimal configuration of gas pipelines, which gives us the opportunity to get a large economic, as well as the effect of preserving the environment, it is also possible to use the pressure drop in the network. In total, with a rational choice of the scheme of organizing gas supply to consumers in localities, it is possible to get the maximum economic effect. It is important that modern equipment of this type allows to implement a single-stage scheme of gas distribution networks. Construction of natural gas pipelines we can use the available pressure drop in various technical solutions, but the reasonable distribution of the pressure drop between the network sections allows us to obtain a positive economic effect. The algorithm shown is proposed for use in the design of gas distribution networks of settlements of all types, and in the supply of natural gas to industrial enterprises.

The economic effect of the implementation of the differential pressure in the gas distribution
