| Summary: | Introduction/purpose: There is a growing interest in pipeline integrity and its
effects on economic and safety aspects. This study examines the process
of corrosion evaluation in order to identify the remaining structural integrity
of thin-walled pipelines with corrosion problems.
Methods: This work aims to create a corrosion evaluation model that can
analyse the deterioration of steel pipes caused by internal pressure. A study
utilised the finite element approach to build models for predicting the burst
pressure of defect-free straight pipes. The study involved analytical and
numerical analysis and used the mathematical extrapolation method.
Results: This paper discusses the impact of several factors on the integrity
of a pipe, including the depth of defects, the thickness of the pipe, the shape,
the size, and the position of faults, as well as the interaction between
internal and external defects. Additionally, the influence of external defects
on the overall integrity is discussed.
Conclusion: It is concluded that the pipeline corrosion failure criterion
(PCORRC) model and the presented model align with the analytical
solution documented in the literature. This holds immense importance in the
field of structural design and safety evaluation. |
