Моніторинг внутрішньої поверхні трубопровідних систем за наявності потенційних дефектів різної форми

Abstract

The prognoses assessments of potential defects on the internal surface of the pipeline systems based on the developed experimental-numerical method for assessment of localized corrosion damaging of welded joints of dissimilar pipes which is based on the electrochemical characteristics of its components and analytical model for determination of corrosion current density on the internal surface of pipe and according to the fracture mechanics approaches were made. At the same time studied the stress state near the top of the simulated defect.
