Determining the failure pressure of defective pipelines is an important part in pipeline
reliability engineering, which affects the assessment of pipelines residual service life. In this …

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 …

Pipeline corrosion defects mostly appear in a colony such that they interact to reduce the
failure pressure, which is not defined by features of a single corrosion defect. The huge …

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 …

The research on the failure pressure of perfect pipeline is the basis of evaluating the bearing
capacity of defective pipeline. The applicability of impact factor of theoretical and empirical …
