Annotation: This article examines the reliability of steel pipes at a random rate of corrosion. A functional exponent relationship of mathematical models of corrosion has been used. It allows to assess the reliability of the element in terms of uniform corrosion under normal law of distribution of the random variable of the initial rate of corrosion. Using this model a diagram of change of the level of reliability during the time for the pipeline diameter of 820, 1 020 and 1 220 mm with a wall thickness of 8 mm is done. The dependence obtained showed that the smaller diameter pipes retain higher levels of reliability than with a large diameter pipelines for over 50 years of operation.
Keywords: steel pipe, corrosion damage, the reliability.
