“…Visual evidence and the results of chemical and metallurgical analyses conducted in the vicinity were employed to examine failure [11,12]. Taking advantage of the finite element method and neural networks, a considerable amount of literature using numerical simulation has been published on the failure of pipeline transportation systems [13][14][15][16][17][18]. Based on the ability to resist hydrostatic pressure, Alamilla et al [19] took the material strength and wall-thickness loss into account to validate the ductile mechanism of mechanical failure in straight pipes.…”

One of the most significant current discussions in fluid transport industry is how to prolong the service life of a metallic pipeline system under severe physical and chemical conditions. Electrochemical corrosion is a persistent problem, causing material degradation and sometimes resulting in serious consequences. Here more than 150 three-point bending tests were done on 82 corroded carbon steel pipes to examine their remaining strength. The current work proposes an artificial protocol to accelerate the electrochemical corrosion of ferrous tubes in a controllable system and analyzed correlations between removed iron mass, the depth of corroded sites, and the deterioration in the mechanical properties of the sample pipes. Based on these correlations, a rough estimate for the retirement life of pipelines is put forward as a referable option.
