FIELD: pipeline transport.
SUBSTANCE: invention can be used in the overhaul of the linear part of the main oil and gas pipelines. The method includes opening a section of an underground pipeline up to the lower generatrix. Then its technical condition, the arrangement of pipelayers and machines is evaluated. The pipeline is lifted taking into account the technical characteristics of the pipelayers in terms of carrying capacity and process parameters of the pipeline lifting in terms of the distance between the pipelayers, the height and force of the pipeline lifting in sections, the length of the curved section. To ensure the strength of the pipeline, the process parameters of the pipeline lifting are determined by the mathematical expressions given in the formula.
EFFECT: exclusion of damage to the pipeline wall due to reduction of mechanical stresses in it and reduction of its lifting efforts by specifying the definition of pipeline lifting process parameters
