Introduction

The gas industry is one of the most rapidly developing sectors of the national economy. A highly efficient fuel and energy complex has been created in our country. The Russian Federation is the only major industrialized country that fully provides itself with fuel and energy from its own natural resources and at the same time exports fuel and electricity.

At the moment, in many parts of public production, natural gas is widely used as an energy carrier, which has become a significant factor in technological progress - an increase in industrial and agricultural output, an increase in public labor productivity and a decrease in specific fuel costs.

Currently, gas has become the main type of fuel in everyday life and public utilities. The Unified Gas Supply System (ESG) of Russia is the largest in the world, created at one time in the Soviet Union, with unique properties due to centralized management, great branching and the presence of parallel routes.

Public utilities are considered in our country as priority gasification facilities. Significant work has been done on the serial production of high-quality plates, automated water heaters, heating devices, special equipment for the effective use of gas in agriculture, equipment for mechanization and automation of technological processes at gas distribution stations. In recent years, telemechanization of urban gas farms has been carried out.

The gas supply system of cities and settlements consists of gas supply sources, gas distribution network and internal equipment.

Sources - main gas pipelines and branches from them, underground gas storage stations (SPHG) and liquefied gas distribution stations.

The gas distribution network is a system of gas pipelines and equipment serving for transport and distribution within the city (settlement, industrial facility).

The internal gas equipment of residential buildings, utilities and industrial enterprises includes internal and industrial gas pipelines, as well as gas devices and gas liquefaction plants.

Modern gas distribution systems are (depending on the facility) a complex complex of structures consisting of the following main elements (1):

1. high, medium and low pressure gas networks;

2. gas distribution stations (GRS);

3. gas control stations (GRP) and units (GRU).
