This study pays attention to the ductile fracture of X80 pipeline steel using both experimental
and numerical approaches. First, nineteen experimental cases are tested, consisting of the …

This paper addresses analytically and numerically the burst strength of ultra-high strength
steel pipelines with corrosion defects based on their elastic-plastic collapse behaviour. First …

The accurate residual strength prediction can support the maintenance planning of
damaged subsea pipeline. Recently, machine learning techniques become a remarkable …

Corrosion defect on pipelines shows a time-dependent growth in service environments.
Prediction of corrosion defect growth and failure pressure of corroded pipelines as a function …

The pipeline is prone to collapse under the combined external pressure and multiple
corrosion defects. Experiments of the full-scale pipelines with longitudinally …

The subsea pipeline is prone to corrosion due to the combined influence of a complex
environment and internal fluid. The corrosion defect results in the local thinning of the wall …

As an efficient and inexpensive tool, pipelines are widely used in the transportation of
hydrogen, carbon dioxide, oil and gas. The subsea pipelines are inevitably corroded …

In the deep-sea environment, pipelines are prone to buckling instability under the coupling
effect of hydrostatic pressure and corrosion defects. This instability phenomenon is affected …

Corrosion is an inevitable issue in oil and gas pipelines, making it critical to accurately
evaluate the remaining bearing capacity of pipelines with corrosion defects. However, the …

Affected by a complex environment, corrosion is a common defect in steel pipelines.
Moreover, steel pipelines are subjected to large axial forces during their installation and …
