FIELD: testing equipment.
SUBSTANCE: according to solution, it involves sampling of a base test section of the pipeline using non-destructive control methods in the re-insulation process of the pipe, blowing of the test medium to critical pressure, determination of indices of mechanical properties of the pipe metal, change of the defect pipe with retesting of the pipe base section for strength and water or air tightness with consequent increment of pressure and rehabilitation of the trunk pipeline. The trunk pipeline is rehabilitated using parameters, initially obtained from the test results of the base section test, while the operational resource of the trunk pipeline is calculated from design.
EFFECT: increasing the effectiveness of rehabilitation of trunk pipeline; accuracy in determining operational resource.
