Abstract null null The article presents the results of investigations of the microstructure and mechanical properties of austenitic, creep-resistant TP347HFG steel in delivery condition and after operation at 585 °C. As-received, the tested steel is characterised by an austenitic structure with twins and NbX precipitates. The conducted studies showed that the operation resulted in precipitation processes, mainly at grain boundaries, where M23C6 carbides and σ phase precipitates were observed. Si...

Abstract null null The paper investigates the Welding Residual Stresses (WRS) of 10CrNi3MoV high strength steel multipass butt welded joints by experimental measurement and numerical calculation considering the effects of weld metal strength mismatch and back-chipping processing. Firstly, a thermo-metallurgical-mechanical simulation model was developed incorporating the Effect of Solid-State Phase Transformation (SSPT) to obtain multipass welding residual stress distributions after the back-chip...

Abstract null null This article attempts to use the laser cladding to realize the metallurgical combination of the ends of L415/316L bimetal mechanical lined pipe. For the convenience of the tests on mechanical properties, two kinds of nickel-based alloy powders, self-fluxing alloy powder (SFAP) and non-self-fluxing alloy powder (NSFAP), were cladded on substrate L415 sheet. The microstructure of two cladding coatings was analyzed by optical microscopy (OM) and scanning electron microscopy (SEM)...

Abstract null null Probabilistic and deterministic integrity analyses of piping are important issues with regard to the integrity and reliability of nuclear power plant (NPP) components. Since there is an ongoing controversial discussion concerning the positive and negative influence of weld residual stress (WRS) on the failure probabilities of piping with dissimilar metal welds (DMWs), we herewith present the analysis of a representative straight pipe with DMW in a boiling water reactor (BWR). ...

Abstract null null The rapid decompression of sub-cooled and supercritical carbon dioxide was investigated experimentally using schlieren and regular high-speed photography. An optically accessible expansion tube was designed and constructed. A test campaign with initial pressures ranging from 6.45–9.02 MPa and initial temperatures from 297–308 K was performed. High-speed schlieren imagery was used to visualize the decompression waves, evaporation waves, and an oscillatory phase change region pr...

Abstract null null 308 L stainless steel is a commonly used cladding material of reactor pressure vessel. Due to the difference of surfacing process, its performance is quite different from that given in the standard. In this study, based on the stress-strain data of cladding 308 L measured in the laboratory, the elastic-plastic analysis of the sealing performance of the spherical head reactor pressure vessel were carried out by ANSYS finite element software. It is shown that the elastic-plastic...

Abstract null null In this paper, an energy difference method is proposed to estimate biaxial stress components based on indentation technique. The indentation energy is chosen as an analytical parameter, which can be calculated directly from the load-depth curve. The presence of residual stress in a material causes the change of indentation energy. The mapping relationship between uniaxial stress and indentation energy difference was established by finite element analysis. Meanwhile, the Knoop ...

Abstract null null The tubular textile composite material is lined on the inner wall of the pipeline by the inversion method, and realizes the structural or semi-structural repair of the pipeline in the form of “pipe in pipe”. Under the action of inversion pressure and working internal pressure, its strength directly affects the repair effect. In this paper, the pressure in the process of inversion and conveying medium is discussed, using theories such as the thin-walled cylinder theory and Hook...

Abstract null null The coupling response of flexible pipe subject to external shear current and internal uniform flow is numerically investigated in this paper. Firstly, without the internal flow being considered, the quantified comparisons of root mean square vibration amplitudes in relation with VIV responses between the numerical results and experimental data were made to verify the efficiency of numerical method. Subsequently, the instantaneous root mean square vibration amplitudes, spanwise...
