Analysis of the tensile strength and elastic modulus of the insulation coating of the pipeline depending on the operating temperature

Corrosion processes occurring in pipelines were researched to improve existing methods for determining the degree of corrosion and clarify existing models on the topic of research. The causes of corrosion in pipelines, corrosion inhibitors are considered. Recalculation was carried out using experimental data from literary sources using Wolfram Mathematica. Graphs were built and approximating functions were selected for each data sample. The adhesion properties of various coatings of pipelines have been investigated, the influence of various factors on the course of corrosion processes has been simulated and the models found in the literature on the research topic have been refined. The correlation between the corrosion intensity and the reliability and durability of the operation of oil pipelines is determined, the influence of adhesion and thermal expansion is considered.
