Abstract:
Corrosion poses a significant risk to the safety of energy pipelines, while landslide disasters emerge as the primary threat responsible for triggering pipeline failures across mountainous areas. To date, there is limited research focused on the safety of energy pipelines considering the synergistic effect of corrosion and landslides. The present study proposes a finite element (FE)-based model to assess the condition of corroded pipelines under landslides. The effects of corrosion dimensions (length and depth) and location are determined. A novel equation is finally developed to predict the m

Abstract:
The transportation of oil and gas in Russia’s northern and Arctic regions has seen significant growth in recent years. However, the presence of permafrost in these areas can cause malfunctions in the main pipelines due to soil frost heaving. The operational pipelines also often suffer from various defects in their body and surface. To mitigate these issues, above-ground trunkline supports are utilized to protect the pipelines from cryogenic processes. Nevertheless, these supports are subjected to ground loads caused by cryogenic frost heaving, which poses a threat to the pipeline’s integrity a

The U.L method is adopted as solving problem about the contact between submarine pipeline and seabed, the results obtained by this method are equally accurate and less computational work is need when solving pipeline’s non-linear great distortion. According to select different original parameter during laying pipeline, the bend distortion to submarine pipeline is calculated and the effect of bend distortion to submarine pipeline is analyzed.

There is a need to accurately design pipelines to meet the expected increase in the construction of carbon dioxide (CO2) pipelines after the signing of the Paris Climate Agreement. CO2 pipelines are usually designed with the assumption of a pure CO2 fluid, even though it usually contains impurities, which affect the critical pressure, critical temperature, phase behaviour, and pressure and temperature changes in the pipeline. The design of CO2 pipelines and the calculation of process parameters and fluid properties is not quite accurate with the assumption of pure CO2 fluids. This paper review

Abstract:
The continuous growth of the global industrial sector has led to an increasing need for the transportation of oil, gas and chemicals through pipelines. The need for compactness of the pipelines along the corridors involves a relatively short distance between one pipe and another, thus leading to a certain degree of risk associated with their potential interaction. Furthermore, as the transported fluids may be flammable, any accidental release due to cracking or leakage in one of the pipelines could lead to an accidental scenario with severe consequences for the population, structures and the e

Buried pipeline networks play a vital role in the transportation of oil and natural gas from centers of production to centers of consumption. A common manufacturing technique for such pipes is the UOE process, where a flat steel plate is first formed into a U shape, then into an O shape, welded at the seam, and mechanically expanded before being shipped on site. The UOE forming process deforms the pipe material plastically and induces residual strains in the pipe. Such pipes are commonly buried on side and then are pressurized under the high head of the fluids they convey which induce hoop st

Geomagnetic activity together with the pipe-to-soil potential have been recorded and correlated to each other. In addition, measurements of instant off potentials together with flow of current to coupons, distributed along the pipeline route were carried out.

Abstract:
Abstract Monoethylene glycol (MEG) is often used to prevent formation of solid gas-hydrates in wet natural gas pipelines when low operating temperatures are expected (e.g. sealines). Glycols have a slightly inhibiting effect on CO2 corrosion, however, corrosion control methods such as pH-stabilisation or corrosion inhibition must be applied unless the CO2 partial pressure is very low. During handling and transportation the glycol may be exposed to air. Injection of oxygen-containing glycol may cause corrosion problems near the inlet of the pipeline. An experimental program has therefore been c

Abstract:
Abstract Several prediction models for CO2 corrosion of oil and gas pipelines have been developed. Most of the models take limited account for multiphase flow effects, and some of the models require separate fluid flow calculations. For multiphase pipelines the variation in flow regime, liquid flow velocity, water wetting and temperature along the pipeline will have a large effect on the prediction of pipeline corrosion. Three of the openly available CO2 corrosion prediction models have been implemented in a commonly used and comprehensive three-phase fluid flow model. This gives the possibili

Abstract:
Abstract The mechanical properties of piping materials in gaseous hydrogen environments are still a complex subject, although steel pipelines have been a major means of transporting gaseous hydrogen for decades. An assessment of the material performance in gaseous hydrogen environments is necessary for safe and reliable pipeline design and operation, not only for existing pipelines but also for new pipelines needed to accommodate future consumption demands. Since the materials for hydrogen pipelines are usually subjected to the repeated loading of pressure fluctuations, fatigue crack growth in

Abstract:
Submarine pipelines are usually laid from the ocean surface onto the ocean floor using specially designed ships and barges. Lengths of pipes are welded together on board the barge to form the pipeline and then the pipeline is passed over a ramp called a stinger on its way to the ocean floor. A constant tension force is applied to the pipeline on the barge to prevent it from buckling as it approaches the ocean floor. For thin wall pipes, the high stresses could result in local buckling of the pipeline. This report describes ananalytical and experimental research study to determine the effect of

Abstract:
Identified the factors that cause pipeline failures and the factors that affect accidents on hazardous liquid pipelines. Since the normalizing of the data was not possible, the authors of this report used indirect and inferential approaches in the analysis. The databases used for this analysis are LIQUID (accident data for 1968-1985) and L1QLCK (accident data for 1985-present). The main finding of this report is that better and more complete data on hazardous liquid accidents should be collected. Other conclusions are that prevention programs should be more effective, and pipe components such

Abstract:
Acoustic emission (AE) proof testing is a particularly attractive method of nondestructively examining large structures such as pressure vessels and pipelines because a total volumetric examination can be made with AE sensors mounted at relatively large intervals over the surface of-the structures. The proof test, to be effective, requires an increase in pressure that is significantly greater than previously applied pressure in order to elicit AE from existing defects. In the case of gas pipelines, however, overpressure of gas in the line represents a considerable risk. It is therefore desirab

Abstract:
�One of the major problems associated with developing fitness-for-purpose procedures for sleeve and branch welds is the prediction of the local stress distribution at the welds. Since the presence of a sleeve or branch will increase the local stiffness of the pipe and give rise to local stress concentration effects, the stress distribution at sleeve or branch welds cannot be readily estimated using simple stress analysis. This project studied the structural behavior of sleeve and branch connections in pipelines. Because these connections create local stress concentration effects, where several

Abstract:
The objective of this study was to determine whether or not gas pipelines have a significant degree of exposure to failure from seam defects that could become enlarged by pressure-cycle-induced fatigue. If there is a potential problem in this respect, then knowing the conditions and times over which defect growth becomes significant, a pipeline operator can prevent failures by carrying out timely pipeline integrity assessments. In this study, times to failure were computed for worst-case hypothetical seam defects that would have barely survived a hydrostatic test to 100 percent of SMYS and sub
