FIELD: pipeline transportation.
SUBSTANCE: invention relates to pipeline transportation and can be used in operation and repair mainlines. A location is marked on the terrain considered to be predisposed to cause the pipe part corrosion cracking under loads (CCL). The said pipe part is disclosed by determining the intersection of the said pipe part with the watercourse. The pipeline is opened by making a prospect-hole through which the CCL origin is decided upon, the said pipe part boundaries are set. The said pipe part is disassembled, a new pipe part is assembled to make an overhead crossing.
EFFECT: elimination of CCL by ruling out the effects of intermittent water flows on the pipeline.
