THE EFFECT OF DENT UNDER FATIGUE LOADING IN PRESSURIZED PIPELINE: A REVIEW
Keywords:Pipeline integrity, dent in pipes, fatigue strength, Stress-life, strain-life, cyclic load
Pipeline integrity is the cornerstone of many industrial and engineering systems. This paper provides a review of all aspects
related to pipeline integrity. Assessment of the fatigue strength and burst strength of steel pipeline is essential consideration in the
components which are subjected to cyclic loads in service. This paper also presents a fatigue life assessment review of failure of steel
pipeline. Failure or deterioration of pipelines takes place by corrosion and fatigue, which later leads to rupture. Stress-life, strain-life, and
linear elastic fracture mechanics crack propagation method has shown to be well accepted as a benchmark model of fatigue assessment.
It shows that choosing an appropriate and accurate method is important; particularly for quantifying the extent to which the fatigue life is
reduced. Good predictions subsequently offer successful designs of pipelines and therefore, any unwanted damage can then be avoided.
