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...
Abstract The pipeline inspection gauge (PIG) is one of the most popular pigging equipment. In recent years, blocking and stagnation accidents during PIG’s operation process seriously affect safe energy pipelines. order to investigate sealing performance rubber cup, a four cup drain movement in elbow was considered as prototype this study. Based on validated finite element model, contact stress between cups pipe wall pressure relief area are obtained. results indicate that when PIG operated...
Abstract Permafrost thawing caused by the hot crude pipeline is a major threat to safe operation of buried pipelines in permafrost zone. In this paper, process and consolidation frozen soil considered, three-dimensional (3D) finite element model zone established using ABAQUS. The calculation thaw settlement displacement based on moisture-heat-stress coupled was carried out, deformation stress were analyzed. effects ground temperature, oil thermal conductivity insulation material distribution...
With the rapid increasing mileage of China’s long-distance oil and gas pipelines, intersection construction with other civil engineering, encroachment by invading pipeline route, third-part problems occurred occasionally. Heavy vehicles rolling serving have become one inevitable safety risks. The field test method three in-service long pipelines under heavy vehicle is elaborated. stress soil pressure during tests are monitored analyzed. parametric model pipe mechanical response stacking load...
Thawing landslide is a common geological disaster in permafrost regions, which seriously threatens the structural safety of oil and gas pipelines crossing regions. Most analytical methods have been used to calculate longitudinal stress buried pipelines. These are subjected slope-thaw slumping load, elastic characteristic soil nonlinear interaction behavior ignored. Also, these not considered real boundary at both ends slope. This study set out introduce an improved method accurately analyze...
Abstract Differential settlement has a significant effect on the safe operation of tanks. In order to investigate stress response crude oil storage tank subjected harmonic settlement. A numerical simulation model steel was developed in this study. Based validated finite element model, parametric analysis conducted based main factors. The results show that at top wall is symmetrically distributed along circumference tank. result increases linearly with increasing amplitude. axial firstly, and...
Abstract Corrosion defects are dreadfully damaging to the stability of pipelines. Using finite element (FE) simulation method, a model API 5L X65 steel pipeline is established in this work study its buckling behavior subjected axial compressive loading. The local state pipe at ultimate capacity was captured. Compared with global strain (CSCglobal), (CSClocal) more conservative. Extensive parametric analysis, including approximately 115 FE cases, conducted influence corrosion defect sizes and...
Large crude oil tanks may face huge risk during operation due to the effect of dangerous and harmful factors. The leakage fire accidents are easy happen which causes serious environmental pollution even casualties. In order ensure safe storage tanks, analysis tank was conducted failure database established based on field survey results. statistical results revealed that explosion main cause failure. evaluation index system derived by accidents. assessment large fuzzy comprehensive method...
