Abstract

Finite element modeling of the stress-strain state of the linear section of the pipeline under non-stationary force load was carried out to determine its residual life. Calculations were made for a pipe made of X60 steel of an oil pipeline with an internal surface crack under turbulent oil flow and hydraulic shock. It was established that hydraulic shocks reduce the residual life of the pipe in almost 2 times compared to laminar oil flow. Therefore, they must be taken into account to guarantee the reliable operation of pipeline transport.
