First, a pair of inspections is aligned at the boundaries between pipe joints. Pattern matching is then used to match individual defects on paired joints. Joint-boundary matching is a correspondence problem that can be described in terms of “drift”, which is the difference in odometry values at corresponding joint boundaries. Here, drift is formalized and characterized. It is used to describe current joint-boundary matching methods — interpolation, zippering, and direct odometry comparison. We use the drift formulation to illustrate why existing methods produce false matches (1) in the presence of poorly documented reroutes, (2) when there are nonlinearities in the odometry from pig speed changes, and (3) from other inspection problems. We develop a new evidence-based intuition for drift as the systematic bias of position-estimating state machines on inspecting pigs. This is followed by deriving a position-specific drift differencing distance metric using the first-order differencing of the drift. We show this value to be trend stationary. The results section compares the four metrics’ abilities to identify common joint-boundary matching challenges. We found that direct matching and interpolation are unreliable. These methods generate difficult-to-detect mistakes because they rely on a nearest-neighbor matching criterion. Zippering and drift differencing work much better. Both rely on pups in the vicinity of pipeline reconfigurations. They both fail when there are no pups or when a reconfiguration is large. Because zippering uses naive pattern-matching, it is subject to aliasing mistakes when non-corresponding joints are in analogous positions. In contrast, drift differencing, which is position-specific, is immune to this type of error. Finally, we show that the assumptions behind the derivation are valid for an example dataset.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"213 ","pages":"Article 105351"},"PeriodicalIF":3.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For enhancing the creep lifetime of P91 steel weldments, the present work proposes a novel post-weld heat treatment strategy to stabilize the tempered martensite structure and avoid Type IV creep cracking. Compared to conventional post-weld tempered treatment weldments, the creep lifetime of as-welded weldment is improved by 1.7 times, while the creep lifetime of weldment subjected to post-weld normalizing followed by tempering is enhanced by 4.6 times, effectively preventing Type IV cracking. It has been revealed that creep weakness zones, that is, soft zones, occur in as-welded weldment and post-welded tempering treatment weldment, where the microstructure is predominantly recrystallized ferrites. Creep fracture always occurs in the region of the highest fraction of recrystallized grains. Post-weld normalizing and subsequent tempering can enhance prior austenite grain size and stabilize tempered martensite structure. For as-welded weldment and post-welded tempering treatment weldment, creep cavities preferentially grow along ferrite grain boundaries as compared to prior austenite grain boundaries, which could easily lead to intergranular premature cracking. For post-weld normalizing and subsequent tempering weldment, cavities form along prior austenite grain boundaries of base metal and are elongated together with martensitic packets/blocks under stress. Finally, the final fracture is caused by the rupture of elongated grains.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"212 ","pages":"Article 105361"},"PeriodicalIF":3.0,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through an analysis of the interaction between slips and tubing, a mathematical model to predict slip-tubing interaction and slip crushing load is formulated, accounting for external pressure, internal pressure, and axial forces. On this basis, the influence factors and influence rules of slip crushing load are studied, and three-dimensional yield surface and tri-axial stress ellipse of tubing are investigated, considering different transverse load factors and design factors. To accurately forecast the fatigue life of tubing subjected to slip indentation, two models are established: one for fatigue life prediction and the other for tubing string vibration. In order to quantitatively assess the stress concentration arising from slip indentation, a finite element model of tubing featuring slip indentation is established. Finite element analysis reveals that stress concentration and non-uniformity are evident in the vicinity of slip indentation, with their severity intensifying as the indentation depth grows. The initial step in assessing fatigue life involves fatigue life tests on tubing material subjected to varying stress levels. Subsequently, a case study is conducted and the variations of wellhead pressure and axial stress are evaluated. Fatigue life analysis reveals that the fatigue life is notably sensitive to variations in stress amplitude and slip indentation depth. An increase in the magnitude of alternating stress and the depth of slip indentation will result in a significant reduction in the fatigue lifespan. The methodologies employed in this research, along with the resulting findings, offer a robust theoretical framework and a solid practical basis for forecasting and managing stress concentration and fatigue durability in tubing affected by slip indentation.</div></div>","PeriodicalId":54946,"journal":{"name":"International Journal of Pressure Vessels and Piping","volume":"212 ","pages":"Article 105360"},"PeriodicalIF":3.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a novel fusion-reinforced joint for RTPs and analyzes its tensile failure mechanism. Two user-defined material (VUMAT) subroutines were developed for unidirectional fiber composites and plain fabric composites to analyze the damage of RTPs and joints. The tensile damage mechanisms were evaluated using the 3D Hashin failure criterion, the maximum strain failure criterion, the residual stiffness model, and the cohesive zone model (CZM). To validate the numerical model, fusion-reinforced joints were designed, machined, and subjected to uniaxial tensile tests. Findings suggest that matrix damage in RTPs is the primary factor contributing to stiffness degradation. The shear stress in the adhesive layer at both ends of the joint reaches the shear strength, resulting in the failure of the adhesive. The tensile process can be divided into four distinct stages: the no-damage stage, the bonding damage stage, the matrix damage stage, and the failure stage. Initially, damage in the adhesive layer leads to a minor decrease in tensile stiffness, followed by significant matrix damage in the RTPs. Failure of the adhesive layer at both ends of the joint gradually propagates to the middle, culminating in the failure of the fusion zone.
