Abstract With continued increasing construction of both electrified facilities and buried high‐strength pipelines in China, stray current corrosion defects have become an nonignorable threat for these pipelines. A comprehensive investigation on a new failure pressure prediction model pipes with was conducted this study. The mechanism steel firstly elaborated brief. After that, parameterized finite element stress analysis external programmed by APDL code developed general software ANSYS. By...
Anomalies as misalignment, microcrack are inevitable for large diameter high strength steel pipelines. To ensure the strain capacity of mismatched welding joint with misalignments D 1,422 mm X80 pipeline, a comprehensive study via wide plate experiments and finite element model simulations was conducted. The full-scale tensile experiment pipe weld Strain distributions on derived by DIC technic. Trends CMOD at precrack in strains monitored. A FE established to inverse prove accuracy numerical...
In recent years, the safety of oil and gas pipelines has become a primary concern for pipeline industry. This paper presents comprehensive study vulnerability concepts that may be used to measure status systems. The origins are identified, development evolution described, main connotations four levels applied in different fields at this stage summarized. Qualitative quantitative methods assessment comprehensively investigated, advantages disadvantages, scope application key issues faced...
The rapid development of offshore oil and gas resources in recent years has led to a steadily growing importance the safety pipelines. Active faults are some main geological hazards which onshore pipelines may be subjected. In this study, an improved analytical method for estimating strains subjected strike-slip fault displacement was proposed. pipe steel considered as linear strain hardening material soil constraint on series elastic–plastic nonlinear springs. Explicit solutions elongation...
Crack-like defects frequently form in pipes exposed to aggressive environments or during welding fabrication. Appropriate strength matching factors should be determined for process evaluation based on the reliability aspect. In this paper, current research status of codes and standards related requirement weld metals pipeline industry were reviewed. The results showed that almost all considered lower limit pipe tensile as a specimens cross-weld test breaking at position. This was...
Abstract A pipeline inspection gauge (PIG) is routinely passed throughout the long‐distance oil and gas pipelines by operators to clean pipeline. Sealing performance a significant evaluation index for PIG's safety operation. To comprehensively evaluate seal performance, nonlinear finite element models were developed, parametric analysis was conducted in this study. The accuracy of simulation model validated from numerical experimental results reported literature. show that comparing with...
The reverse fault is a dangerous geological hazard faced by buried steel pipelines. Permanent ground deformation along the trace will induce large compressive strain leading to buckling failure of pipe. A hybrid pipe-shell element based numerical model programed INP code supported ABAQUS solver was proposed in this study explore performance X80 pipeline under displacement. Accuracy validated previous full scale experimental results. Based on model, parametric analysis conducted effects four...
