This paper presents an updated review of the external corrosion and failure mechanisms of
buried natural gas and oil pipelines. Various forms of external corrosion and failure …

In recent years, pipeline failures attributed to circumferential stress corrosion cracking (C-
SCC) in near-neutral pH environments were reported. The environmental conditions that led …

Circumferential near-neutral pH corrosion fatigue (C-NNpH-CF) occurs when the external
surface of a buried pipeline is simultaneously subjected to both axial residual stresses and …

This chapter presents the latest progress made in modeling and prediction of stress
corrosion cracking (SCC) of pipeline steels. The chapter starts first by defining field …

Circumferential near-neutral pH corrosion fatigue (C-NNpH-CF) is the result of the
simultaneous impact of axial residual and applied stresses along with the near-neutral pH …

This study confirms that" Near-neutral pH Stress Corrosion Cracking" in steel pipelines
propagates by hydrogen-enhanced corrosion fatigue. A critical cyclic loading frequency …

The purpose of this study is to identify the integrity challenges encountered by buried
pipeline steels, specifically to address Circumferential Near-Neutral pH Corrosion Fatigue …

In this investigation, analyses of pressure fluctuations during oil and gas pipeline operations
are performed. The analyses are performed in a way to capture all the variables of pressure …

Stress corrosion cracking (SCC) can cause catastrophic failure of buried pipelines for oil and
gas transmission. The life cycle of pipeline steels experiencing SCC consists of five stages …

This research investigates a methodology for probabilistic life prediction of buried steel
pipelines subjected to external corrosion. A unified methodology is developed considering …
