Abstract:

Reliability analysis of corroded pipelines is critical to the integrity and safe working of pipeline infrastructure. Aiming at less probability information is obtained for corrosion pipeline engineering, and the mechanical properties of pipeline with corrosion defects deteriorate caused by the accumulative effect of corrosion growth. Based on the quasi-static analysis method and non-probability theory, this paper presents a reliability model for assessing corroded pipelines with corrosion growth. In fact, reliability analysis of corroded pipelines needs to consider the interaction of multiple

Abstract:

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 operation. Corroded deep-sea steel pipelines are prone to local buckling under complex loads. Therefore, in view of this problem, the collapse response of corroded steel pipelines under the combined axial force and external pressure is analyzed in detail. First, a formula for evaluating the collapse pressure of corroded steel pipelines under external pressure and axial force is proposed. Then, the factors affecting the c

Abstract:

Abstract Corrosion is accountable for numerous malfunctions and leakages in gas pipelines. In instances of external corrosion, due to the internal pressure within the pipes, stress concentrations can occur around the corroded areas. These, in the presence of cavities or cracks resulting from corrosion, may amplify the risk of pipeline failure. Consequently, as the wall thickness diminishes due to corrosion, the pipeline’s ability to withstand internal pressure declines. In the case of corrosion, the pressure at which a corroded pipe might collapse is significantly lower than that of an uncorro

As corrosion reduces the wall thickness of the pipe, its ability to withstand internal pressures decreases significantly.

The paper introduces a computer vision methodology for detecting pitting corrosion in gas pipelines. To achieve this, a dataset comprising 576,000 images of pipelines with and without pitting corrosion was curated. A custom-designed and optimized convolutional neural network (CNN) was employed for binary classification, distinguishing between corroded and non-corroded images. This CNN architecture, despite having relatively few parameters compared to existing CNN classifiers, achieved a notably high classification accuracy of 98.44%. The proposed CNN outperformed many contemporary classifiers

Abstract:

Sensitivity analysis aids in determining important factors affecting pipeline safety. Sensitivity analysis of stress inside gas pipelines with corrosion defects in a landslide region can provide a theoretical basis for the safe operation of pipelines. This study considered an X80 high-grade steel gas pipeline model with corrosion defects using finite element analysis (ABAQUS software) under lateral landslide conditions. Particularly, we studied the six major engineering elements of soil cohesion to understand the stress variations in buried gas pipelines and performed a sensitivity analysis of

Abstract:

The evaluation of the failure probability of corroded pipelines is an important calculation to quantify the risk assessment and integrity of pipelines. Traditional Monte Carlo simulation method has been widely used to solve this type of problems, where it generates a very large number of simulations and takes longer time in computing. In this study, enhanced computational method called Separable Monte Carlo is employed to evaluate the time-dependent reliability of pipeline segments containing active corrosion defects, where a practical example was used. The results show that the Separable Mont

Abstract:

The significance of oil and gas pipelines in the exploration and production of oil and gas resources is well-documented. However, these pipelines are subject to a number of challenges that can compromise their integrity and operational efficiency. These challenges include structural defects, geological disasters such as earthquakes, landslides, debris flows, and land subsidence, as well as external forces such as dynamic impact forces, shear forces, extrusion forces, and uneven settlement forces. These defects can be exacerbated, thereby increasing the risk of pipeline failure. To accurately e

Abstract:

Abstract The residual strength of corroded defective pipelines is an important manifestation of pipeline-bearing capacity. The change of residual strength of Q235 steel and B10 Cu-Ni alloy pipeline caused by the change of defect depth, length, and width in the case of grooved corrosion defect was analyzed and studied by the finite element method. The results show that the effect of corrosion defect depth on the residual strength is greater than the defect length and width. At the same time, Q235 steel has better pressure-bearing performance than B10 Cu-Ni alloy.

Maintenance and integrity management of hydrocarbons pipelines face the challenges from uncertainties in the data available. This paper demonstrates a way for pipeline remaining service life prediction that integrates structural reliability analysis, accumulated corrosion knowledge, and inspection data on a sound mathematical foundation. Pipeline defects depth grows with time according to an empirical corrosion power law, and this is checked for leakage and rupture probability. The pipeline operating pressure is checked with the degraded failure pressure given by ASME B31G code for rupture lik

None could grow at temperatures higher than 40 °C. All the isolates grew at 1% (w/v) NaCl while none could grow at 8% (w/v) NaCl. All the isolates grew at pH 7 .0 -7 .5 .

Recently, corrosion perforation has been frequently seen in surface pipelines in the oil and gas industry, resulting in operational and environmental challenges. Due to the complex characteristics and mechanisms of such corrosion, a new and pragmatic method has been designed to identify and evaluate the corrosion phenomenon via a hanging ring installed in a surface pipeline. In addition to respectively analyzing the ions of water samples with chemical titration, ion chromatography, and mass spectrometry, the micro-surface morphology of the corroded hanging rings was observed and evaluated by u

Abstract:

Currently, corrosion of the pipeline wall of main oil and gas pipelines is one of the main reasons for their failures and accidents. A decrease in the pipeline wall thickness due to corrosion leads to a significant decrease in the load-bearing capacity (strength) of the pipes and an increase of mechanical stress in their wall. As a result, the probability of a pipe wall rupture increases. In some cases, a pipe wall rupture leads to ignition of the pumped product. This is especially typical for gas pipeline damage. In order to eliminate the possibility of a fire, it is necessary to promptly det

This paper presents a method for assessing the reliability of a corroded pipeline placed in series, with special consideration given to the effect of the length scale imposed by each segment of the pipe. The features of corrosion in different pipe segments are statistically correlated; thus, a failure in one section may impact the adjacent sections. Herein, using a correlation distance parameter, such statistical correlation is described considering the length-scale effects. The reliability of the corroded pipeline is presented in the form of a failure probability. The results show that analys

This study aimed to present a numerical analysis to assess the corrosion factor influencing the residual burst pressure and stress behaviour of Malaysian coastal subsea pipelines. Statistical analyses were carried out to investigate the correlation of point damage location and position of defect area to the burst pressure which was determined using DNV RP F101 codes. Eight critical models were analysed by using finite element method to access the stress behaviour. Based on the results, it was observed that critical frequency of corrosion happened at three locations (i.e. 50 m, 900 m and 1500 m

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.
