Ultimately, lifetime prediction models assess the amount of damage a material undergoes during a typical service cycle and the cumulative damage a material can withstand prior to failure. However, not all damage processes are equal, and neither is the manner in which mechanical loading translates to damage the same when materials are in inert environments compared to in hydrogen environments. For example, in the three leading proposed mechanisms of hydrogen embrittlement (Hydrogen-Enhanced Decohesion (HEDE), the Hydrogen-Enhanced Localized Plasticity (HELP), and the Nano-Void Coalescence (NVC)), hydrogen is proposed to enhance the manifestation of grain separation, dislocation generation/movement, and void coalescence, respectively. A full understanding of the damage modes requires a measurement capable of probing all three mechanisms at once. Here we present simultaneous High Energy X-ray Diffraction (HEXRD) and Small-Angle X-ray Scattering (SAXS) during fatiguing of steel in hydrogen. HEXRD measurements probe strain and dislocation density; SAXS measurements probe nano-pore generation and coalescence.

Several factors may contribute to minimum weld spacing requirements, including metallurgical, geometrical, residual stresses, and even aesthetics. It is not uncommon to hear concerns expressed about the metallurgical interaction of adjacent welds, in terms of overlapping heat-affected zones (HAZs). However, overlapping or interacting HAZs do not become a concern unless welds are spaced very closely, as HAZ widths for typical pipeline welds are generally less than 0.25 in. (6.4 mm). Often, minimum weld spacing requirements are based upon geometrical reasons, such as avoiding overlapping stress concentrations at the weld toes or allowing adequate access for inspection equipment following welding. Or, they may be based upon residual stresses, and the avoidance of overlapping residual stress fields and distortion, which are influenced by pipe dimensions and the welding procedure and could approach a few inches in distance. Finally, weld spacing requirements, especially for new construction applications, may simply be based upon aesthetics, where the flexibility exists to separate welds by a distance that makes sense from a visual perspective. Examples of company-imposed and code-based minimum requirements are provided that can used to perform a critical assessment of current company requirements or develop new requirements.</p></div>","PeriodicalId":100824,"journal":{"name":"Journal of Pipeline Science and Engineering","volume":"2 3","pages":"Article 100073"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667143322000452/pdfft?md5=85f9ec7b183fe638be0c3557bb006df3&pid=1-s2.0-S2667143322000452-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75670981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of particle size, various backfill material properties, and backfill depth on the fracture velocity were examined. It was found that the particle size had a minor effect on the fracture velocity and should be selected in proportion to the diameter of the pipe being examined. The numerical study showed that increasing the density and shear modulus of the backfill material resulted in a reduction of the fracture velocity. The effect of backfill depth up to 1.4 m was also examined numerically and found to have little effect on the fracture velocity, agreeing well with literature.

For a safe operation and limited resource consumption it is necessary to clarify the product requirements. The semi-finished products medium and large line pipes and bends are regarded over the production chain: pre-material, hot rolled strip, welded pipes, and induction bent pipes.

For hydrogen gas, the surface reaction with steel is considerably reduced compared to other corrosion reactions i.e. with sour gas. This results in a much lower amount of introduced hydrogen atoms within the material.

Furthermore, results of tests of applicability of commonly used flow coats in hydrogen atmosphere are shown. For a possible failure scenario of a hydrogen transport line the investigations must be focused on local effects of hydrogen enrichment in conjunction with mechanical loads.

Laboratory tests investigating the effect of hydrogen on the mechanical properties of pipeline steels have shown that even low partial pressures of hydrogen can substantially reduce properties such as reduction in area and fracture toughness, and increase fatigue crack growth rates. However, qualitative arguments suggest that the effects on pipelines may not be as severe as predicted from the small scale tests. If the trends seen in laboratory tests do occur in service, there are implications for the assessment of damage such as volumetric corrosion, dents and mechanical interference. Most pipeline damage assessment methods are semi-empirical and have been calibrated with data from full scale tests that did not involve hydrogen. Hence the European Pipeline Research Group (EPRG) commissioned a study to investigate damage assessment methods in the presence of hydrogen. Two example pipeline designs were considered, both were assessed assuming a modern, high performance material and an older material. From these analyses, the numerical results show that the high toughness material will tolerate damage even if the properties are degraded by hydrogen exposure. However, low toughness materials may not be able to tolerate some types of severe damage. If the predictions are realistic, operators may have to repair more damage or reduce operating pressures. Furthermore, damage involving cracking may not satisfy the ASME B31.12 requirements for preventing time dependent crack growth. Further work is required to determine if the effects predicted using small scale laboratory test data will occur in practice.</p></div>","PeriodicalId":100824,"journal":{"name":"Journal of Pipeline Science and Engineering","volume":"2 3","pages":"Article 100066"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667143322000385/pdfft?md5=d32b8a061e6c5ba9f86862cc1b52c7b5&pid=1-s2.0-S2667143322000385-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"137374708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed model is demonstrated on an internally corroded offshore natural gas pipeline segment with multiple initial defects; and considers disruptive events arising from the leak, burst, and rupture failure modes. The resilience index and sensitivity analysis are evaluated for the offshore pipeline. The pipeline sensitivity analysis indicates the apparent effect of pipe wall thickness and defect depth growth rate on resilience over its design life.

Leakages usually can occur in pipelines due to aging, corrosion, metal failure, etc. When an accident happened, not only the energy company would take the financial loss, but also it would cause pollution and safety issues to the local environment. Therefore, an efficient way to identify leakages in parallel pipelines is necessary to be proposed. In this study, ANSYS was used to simulate different leak scenarios in parallel pipelines. Fluid and pipe parameters were used to simulate different leak scenarios. In each leak scenario, there were different pressure drops along the leak pipeline based on leak locations and different flow rates. After determining there is more than a leak in pipelines, the relationship among pressure drops, leak locations, and flow rates can be used to build a mathematical model for detecting leaks. During the pipeline operations, the pressure drops were affected by leak locations and flow rates. Therefore, applying flow parameters in real leak scenarios to the mathematical model that is built from the parameters in the reality will identify the leak locations. In addition, lab experiments were applied to verify the validity of the simulations. The deviations between the experiments and simulations are less than 4%. The pressure drops through the leak pipe in the experiments and simulation vary from 1,955 to 2,898 Pa and 1,992 to 2,803 Pa, respectively.
