FIELD: gas industry.
SUBSTANCE: invention relates to methods used in gas industry during installation of pulse lines on sections of gas pipeline laid in conditions of moving soil, wetlands in the presence of dynamics of ground motions and, as a result, deviation (from project marks) of risers of pulse gas extraction with possible occurrence of breaks of metal tubes (threaded joints) and formation of gas leaks.
EFFECT: essence of invention consists in fact, that supply of pulsed gas to required points of gas supply is made with not steel tubes, and by means of flexible high-pressure hoses from multilayer thermoplastic hose and is mounted taking into account presence of additional margin along length (sag) with possibility of free stroke in three directions.
