Abstract
The consequence of pipeline failure can be economically, socially, and
environmentally devastating, which can cause massive costs for repair, enormous
disruption of daily life, extensive pollution, and even human injuries. This necessitates
a comprehensive procedure to estimate the likelihood of pipe failures and their
remaining safe service life.
Strength of a pipe is affected by corrosion-induced reduction of the pipe wall.
Therefore, it is of paramount importance to incorporate the effect of corrosion pit into
the structural analysis of a pipeline. In this chapter reliability-based methodologies
explained in Chapter 4 will be used for assessment of corroding pipes in four case
studies. To cover a wide range of pipelines, case studies on oil and gas pipelines,
steel water pipes, cast iron water pipes, and concrete sewers will be presented.
