The gas pipeline is an important element of the gas supply system, as 70-80% of all capital investments are spent on its construction. At the same time, 80% of the total length of gas distribution networks is accounted for by low-pressure gas pipelines and 20% by medium and high-pressure gas pipelines. Low-pressure gas pipelines are used to supply gas to residential buildings, public buildings and municipal enterprises Medium-pressure gas pipelines through gas control points (hydraulic fracturing) supply gas to low-pressure gas pipelines, as well as industrial and municipal enterprises. Through high-pressure gas pipelines, gas flows through gas distribution units (GRU) to industrial enterprises and medium-pressure gas pipelines. Communication between consumers and gas pipelines of various pressures is carried out through hydraulic fracturing and GRU and GRPSH.
