Abstract
The main source of energy in the economy is gas fuel. The specific weight of natural gas in the fuel and energy balance is about 50%. †The main requirement for the gas distribution system is to ensure the reliability, safety of this system. One of the ways to improve the reliability of gas supply systems is to use the reliability of automatic equipment to determine the gas contamination of premises. Based on the analysis of calculation formulas, an algorithm for the hydraulic calculation of gas pipelines is compiled. Based on the characteristics of gas distribution systems, it is advisable to apply such a solution, when gas supply of domestic consumers, boiler houses of municipal agricultural enterprises is carried out from the distribution network of high and medium pressure through autonomous combined pressure regulators installed in areas of high-rise buildings.

The history of the Russian gas industry originates in 1899, when the first gas lanterns were lit in St
The pipeline is subjected to additional loads - groundwater recharge, soil punching, backfilling, forces caused by a change in pipeline temperature. These and other external factors are taken into account by the safety factor c = 2.5 when calculating the working pressure in the gas pipeline (MOP) for a period of 50 years [4, 13]
Based on the peculiarities of the system of gas distribution of populated areas, it is advisable to apply such a technical solution, in which gas supply to household consumers, boiler houses, municipal and agricultural enterprises is carried out from the distribution network of high and medium pressure through autonomous combined pressure regulators installed near high-rise buildings
Summary
The history of the Russian gas industry originates in 1899, when the first gas lanterns were lit in St. In Baku, the largest oil-producing region of the Russian Empire, in 1917, 33 million m3 of gas was used. In 1948, the Main Directorate for Natural Gas Production was established. In 1956, it was transformed into the Main Directorate of the Gas Industry, and into the State Committee for the Gas Industry. In the second half of the 1970s, gas production in the USSR increased by 4.8 times, and in 1984 the country came out on top in the world in terms of its production - about 590 billion m3 per year. In 1970-1980 in Western Siberia, the largest natural gas fields: Vyngapurovskoye, Medvezhye, Urengoiskoye, Yamburgskoye, were discovered, huge gas reserves were discovered on the Yamal Peninsula. Super heavy gas mains were laid in the central and western regions of the country
