Abstract

Distributions of wall thicknesses differing from their nominal values are analyzed, and factors facilitating the formation of thicknesses equal to and exceeding their nominal values are considered. It is shown that the nominal and mean thickness values calculated using the full volume of field examination data have to be used in calculating the rates of erosion-corrosion wear and predicting the service life of pipelines.
