Abstract
On the basis of the mathematical model of electrochemical corrosion of the pipeline in the fracture of the insulating coating under the action of an aggressive metal electrolytic pipeline, a dependence was obtained which allows us to calculate the relative loss of the cross-sectional area of the pipeline wall in the work of the macroscopic corrosion pairs under the conditions of stable presence of the aggressive solution in the damaged zone. The advantage of this model is the ability to predict the development of corrosion in time, regardless of the chemical composition of the aggressive electrolyte, the possibility of obtaining the required calculation parameters on the structures, operated, in a non-destructive way. The developed dependence of the losses of the sectional area of the pipeline allows us to rationally plan repair work, to predict the real terms of the work of the structure, to review the operation mode, etc. The obtained results allow us to more reliably estimate the bearing capacity of structures working under aggressive environment with cracks and provide environmental safety.
