FIELD: gas transportation; gas pipe lines not equipped with stationary chambers for injection and reception of inter-tube diagnostic and cleaning tools. SUBSTANCE: proposed method includes selection of pipe line section to be subjected to inter-tube inspection and passing inter-tube inspection tools through this section via injection and reception chambers made in form of tubes; their connecting diameter corresponds to diameter of gas pipe line; they are provided with cutoff cocks and gate and are temporarily connected to operating gas line through vent fittings of line cocks located near section to be inspected. Proposed method may be used for performing random major repair of pipe line sections not equipped with stationary injection and reception chambers of inspection tools. EFFECT: enhanced efficiency and reliability. 2 dwg
