Environmental justification of the distribution of pressure drop in a dead-end low-pressure gas network

Abstract

The gas supply system is determined by the classes of the elements of the gas transmission network associated with the pressure of the pumped natural gas. Laying gas pipelines in urban areas requires sufficient space around the pipes as a safety zone. The gas pipelines of the first level include gas communications in which the methane pressure is high or medium. To eliminate dead-end sections, gas pipelines are backed up (duplicating individual segments or ringing). The creation of a dead-end network is allowed only in small settlements. Dead-end network is a gas pipeline branching in various directions to gas consumers. Each section of the branched network has a one-way power supply.
