The finite element models of corroded pipelines with colony of defects composed of two
longitudinal or circumferential aligned defects, and four defects arranged in rhombus shape …

This study investigates the burst capacities of corroded pipelines using three-dimensional
elasto-plastic finite element analyses validated by full-scale burst tests of corroded pipe …

Corrosion defects, also called metal loss due to corrosion, are frequently found in carbon
steel pipelines. Corrosion defects may occur singly or in colonies. Usually the failure …

Burst pressure prediction of pipelines with interacting defects is essential in the integrity
assessment of steel pipelines. A series of evaluation criteria have been proposed to predict …

The relation between the failure pressure of pipeline with irregular-shaped defect and the
characteristic geometric parameters is more complex than regular-shaped defect. Therefore …

The present study proposes a new burst capacity model for corroded oil and gas pipelines
based on extensive parametric three-dimensional (3D) elasto-plastic FEA validated by full …

This paper presents a new methodology for the prediction of pipelines failure pressure that
uses axisymmetric modeling of pipelines which uses the River Bottom Profile (RBP) of the …

Extensive parametric three-dimensional elasto-plastic finite element analyses are carried
out to investigate the interaction effect on the burst capacity of oil and gas pipelines …

The interaction between axially adjacent defects is more significant than that between
circumferentially aligned defects. However, the existing failure pressure assessment …

The accurate prediction of failure pressures in pipelines containing multiple defects is
important for assessing the integrity and reliability of corroded pipelines. First, the effect of …
