“…For example, recently Zhu and Leis [5] examined the burst pressure prediction of over 100 uncracked pipes while Bedairi et al [6] examined the influence of corrosion defects on fracture. Another study involved a large number of large-scale tests on straight pipes and elbows of various pipe sizes and crack configurations subjected to different loading conditions, as summarised by Chattopadhyay et al [7,8] and assessed recently in [9].…”

This paper reports fracture assessments of large-scale straight pipes and elbows of various pipe diameters and crack sizes. The assessments estimate the load for ductile fracture initiation using the failure assessment diagram method. Recent solutions in the literature for stress intensity factor and limit load provide the analysis inputs. An assessment of constraint effects is also performed using recent solutions for elastic T-stress. It is found that predictions of initiation load are close to the experimental values for straight pipes under pure bending. For elbows, there is generally increased conservatism in the sense that the experimental loads are greater than those predicted. The effects of constraint are found not to be a major contributor to the initiation fracture assessments but may have some influence on the ductile crack extension.

“…Underground pipelines are subject to tension and compression stresses from the surrounding soil and their internal pressure, which make the hoop stress to be the maximum principal stress and the radial stress to be negligible. For a yield failure and a posterior plastic collapse evaluation, different criteria like the Tresca (Maximum Shear Stress Theory), Von Mises (Maximum Distortion Energy), or ASSY (Average Shear Stress Yield) are commonly implemented for corroded pipelines [24,25].…”

“…Maes et al [35] considered the combined effect of burst pressure with tension or bending. Law & Bowie [37] and Zhu & Leis [25] reported other models that can predict the burst pressure of intact pipelines. From these models, it is highlighted the use of the Barlow equation with the ultimate strength as hoop stress, and the approaches from Fletcher, Maximum Shear Stress, Turner, ASME boiler code, and Bailey-Nadai.…”

Corrosion is one of the most significant threats for onshore pipelines that may lead to a Loss of Containment (LOC). A LOC poses significant consequences over the surrounding people and environment because of the hazardousness of the transporting fluids, so different efforts have been raised to predict pipe failures, which are commonly based on reliability assessments with limit state functions. These functions are gathered in serviceability, leakage, and ultimate conditions, out of which the last two approaches contemplate a LOC. This paper reviews recognized limit state functions for corroded pipelines, and it discusses their assumptions and applicability. Specifically, this paper focuses on burst limit pressures considering the relevance in the academic literature and Oil & Gas standards. Therefore, a thorough comparison is presented based on failure criteria, acceptable defect dimensions, failure probability, and error prediction based on experimental and numerical burst tests. The objective is to evaluate the level of conservatism of each simplified model depending on the material toughness and the corrosion rate. This review aims to support a reliability model selection in corroded pipelines for future intervention strategies.

“…DNV and BG have then developed a uniform DNV RP F101 [12] guideline to test corroded pipelines, based on finite element analysis and experimental studies. Several significant experimental and numerical studies were recently conducted by Cronin [13], Choi et al [14], Netto et al [15], Cosham et al [16], Chiodo and Ruggieri [17], Majid et al [18], Huang and Zhou [19], Zhu and Leis [20], Ma et al [21], Fekete and Varga [22], Alamilla et al [23], Abdalla Filho et al [24]. Though, their contributions are important, but focalized only on pipelines simple corrosion.…”

This work focuses on a development of a finite element model that simulates corrosion phenomenon and its influence on structure rupture (pipelines). Subsequently, the pitting effect on reliability and pipelines lifetime is studied. In this paper, the investigated structure material is characterized experimentally, in order to determine the maximum strength and stress resistance. Therefore, a numerical model was developed under ANSYS code to simulate different loads to obtain the stress concentration factor as the stresses could surpass the yielding limit in the corrosion impact, and to determine the Von Mises stress. A corrosion model and residual stresses used in the literature are coupled with the probabilistic model to find the limit state function. Thus, failure probability and structure reliability index under the effect of pitting corrosion phenomena are calculated and the obtained results are discussed and analyzed.
