Abstract ：
The accurate prediction of failure pressures in pipelines containing multiple defects is important for assessing the integrity and reliability of corroded pipelines. First, the effect of the remaining defects on the failure pressure of the pipeline containing triple defects was investigated by developing the finite element (FE) model of pipelines containing triple defects. Then, to integrate machine learning method and finite element models to establish a prediction model for the interaction coefficients corresponding to combined corrosion defects. Subsequently, a framework for predicting the burst pressure of pipelines appliable to the scenario of group corrosion defects was proposed by integrating the interacting coefficient and the failure pressure of single defect. Finally, the accuracy of the model was demonstrated by the evaluation indicators and bursting experimental data of corroded pipeline containing cluster defects. The framework is expected to provide a maintenance foundation for the integrity assessment of pipelines with clustered corrosion defects.

Abstract ：
In this work, the effects of different nutrient contents in simulated soil solution containing sulfate-reducing bacteria (SRB) on the corrosion of X80 pipeline steel were studied. The highest amount of sessile SRB was found in the initial medium concentration of 1/3, followed by the concentration of 10%, and the lowest in the simulated soil solution without culture medium. However, the biofilm formed in the simulated soil solution without culture medium had the strongest adhesion and corrosiveness, with X80 steel having the highest corrosion rate, which was approximately 7.2 times of the initial medium concentration of 1/3. The research results have a positive role in promoting the development of SRB corrosion prevention technology for buried pipeline.

Abstract ：
[目的]文中旨在研究不同温度下焊接残余应力对含裂纹P91 钢蒸汽管道断裂行为的影响机制,通过数值模拟和试验验证,评估焊接残余应力对管道完整性和安全运行的潜在威胁.[方法]通过CT试样试验验证了有限元模型的可靠性,建立了P91 钢蒸汽管道的含裂纹焊接模型,并采用生死单元技术模拟焊接过程,运用热传递模块计算焊接过程温度场,通过热力耦合得出了焊接应力场的分布模式.[结果]焊接残余应力在焊接完成后沿焊缝中心对称分布,沿轴向方向朝两端递减,在管道厚度方向上,从内层到外层呈现波浪状的增减的分布规律,其中周向应力的数值最大.当管道中引入初始裂纹后,裂纹尖端区域产生了明显的应力集中现象,其中裂纹中心部分呈现拉应力,而裂纹两端呈现压应力.远离裂纹尖端韧带部分,焊接残余应力几乎不受裂纹引入的影响.随着温度的升高,焊接残余应力逐渐降低,并且不同温度下的焊接残余应力的分布规律保持相似.焊接残余应力显著降低了P91 管道的启裂内压,并且随着温度的升高,降低比例逐渐增大,在 800℃时,焊接残余应力单独作用即可导致裂纹启裂.焊接残余应力对管道启裂过程中的应力分布具有重要影响,沿管道厚度方向,周向应力在裂纹尖端位置迅速上升,并在一段距离达到最大值,沿管道裂纹尖端方向,裂纹中心附近应力均趋于稳定,然后迅速下降,在裂纹末端趋于平稳,并且在较高温度时裂纹末端可能会转变为压应力.[结论]焊接残余应力降低了P91 钢管道的启裂内压,随着温度升高降低比例越大,焊接残余应力促进了裂纹中心的启裂,抑制了裂纹两端的启裂,焊接残余应力还降低了启裂时裂尖所需应力,增大了裂纹区域的应力梯度,导致不同温度下裂纹区域的应力分布和启裂位置有所不同.

Abstract ：
The influence of temperature on hydrogen diffusion and hydrogen embrittlement of X80 steel was studied using electrochemical hydrogen charging. The hydrogen diffusion and subsurface hydrogen concentration in the steel increased with increasing the temperature. Macro slow strain rate tensile tests and microstructural analysis were performed to unveil the dependence of hydrogen-induced embrittlement susceptibility on temperature, which suggested a temperature threshold THE, max of 315 K. The demonstration of THE, max would be crucial for determining test temperatures of hydrogen-related engineering material applications.

Abstract ：
The corrosion mechanism of X80 steel in simulated solutions of acid red soil and product oil sediment under mechano‐electrochemical interaction (MEI) was researched to build a new finite element model through multi‐physical field coupling simulation technology. Based on the new model, the effect of external wall defect growth on the internal wall corrosion of oil pipelines was analyzed in detail. The results showed that the distributions of stress and corrosion of the internal wall were extremely affected by the external wall defect depth, and the corrosion rate of the internal wall was enlarged remarkably by the external wall defect growth. Moreover, attributing to the local galvanic cell effect under MEI, the growth rates of corrosion defects in the depth and length directions of the external defect were accelerated because these directions were associated with larger stress and equivalent to the anode, but the corrosion rate in the width direction of the external defect was inhibited because this direction was associated with smaller stress and equivalent to the cathode.

Abstract ：
Serious crevice corrosion was detected at wear ring and pump casing of an S32760 duplex stainless steel fire pump assembled on an offshore platform, which resulted in broken of the wear ring. The failure mechanism of the cracked wear ring was analyzed, and results showed that the chemical composition of the wear ring corresponds to the standard S32760. However, metallographic test results showed that the wear ring has many harmful sigma-phases and inclusions in the matrix, which led to the decrease of corrosion resistance of the material and induced crevice corrosion at the bolt joint and the wear ring. Besides, Chloride, sulfide, sodium and potassium have been found at corrosion products and pump casing fragments through energy dispersive X-ray spectrometry. Thus, to extend the service life of the fire pump, better sealing measures are needed to prevent crevice corrosion.

Abstract ：
通过平面断裂韧度实验对紧凑拉伸(CT)试样的力学性能进行研究,分析了尖裂纹和钝裂纹试样的断裂形貌特征,并定量分析了裂纹尖端钝化对力学性能的影响.实验结果表明,尖裂纹计算得出的断裂韧度值、最大断裂值、塑性分量和最大位移量都小于钝裂纹对应的数值,裂纹尖端形成的钝化区有利于抑制裂纹扩展,提高了抵抗断裂的能力,能够达到止裂的目的.随着裂纹尖端曲率半径的不断增加,存在最佳钝裂纹曲率半径.当曲率半径超过其值,刚度出现轻微退化,塑性分量在外加载荷输入能量中所占的比重越来越大,断裂韧度提升明显,增强了试样的承载能力.研究结果可为定量评价裂纹尖端钝化对力学性能的影响提供科学依据.

Abstract ：
A 3-dimensional finite element model was built to determine the effect of inclination angle of a corrosion defect on local mechano-electrochemical (M-E) effect in a simulated soil solution. Because of the high effect of the defect inclination angle on the M-E effect, when the inclination angle is 0 degrees (i.e., the primary axis of the defect parallel to the longitudinal direction of the pipe), the greatest stress concentration level at the defect can be observed, which is associated with the lowest corrosion potential, the greatest anodic current density and the most serious accelerated localized corrosion. When the inclination angle is 90 degrees, the stress concentration level reduces and the corrosion potential becomes less negative, accompanying with the decreased anodic/cathodic current densities. Besides, when the ratio (r(ca)) of the primary axial length of the defect to its secondary axial length is 1, the defect inclination does not affect the stress and the electrochemical corrosion rate at the defect. With the increase of r(ca), the effect of the defect inclination angle is more apparent. (C) 2021 The Authors. Publishing services by Elsevier B.V. on behalf of KeAi Communications Co. Ltd.

Abstract ：
Local corrosion at a defect on a pipeline was assessed using both 2-dimensional (2D) and 3-dimensional (3D) finite element models under mechano-electrochemical (M-E) interaction. While the M-E interaction increases corrosion activity at the defect, the assessment of M-E interaction would have different results using 2D and 3D models. Compared with the 3D model, the 2D model produces a greater local stress, a higher local plastic strain, a more negative corrosion potential and a higher anodic current density at the defect, and thus, a lower threshold internal pressure causing local yielding. The 3D model is more conservative for corrosion rate prediction of corroded pipelines. A new concept, rAZ (the ratio of the anodic zone length to defect length in the 2D model, or the ratio of the anodic zone area to the defect area in the 3D model), is proposed to define growth mode of the corrosion defect. There is a smaller rAZ produced in 2D model. At specific internal pressures, the 2D model predicts an ellipsoidal defect center area experiencing accelerated corrosion and potentially resulting in pipeline leaking.
