The aim of this research was to investigate the influence of metallurgy on the corrosion behaviour of separate weld zone (WZ) and parent plate (PP) regions of X65 pipeline steel in a solution of deionised water saturated with CO2, at two different temperatures (55 °C and 80 °C) and at initial pH~4.0. In addition, a non-electrochemical immersion experiment was also performed at 80 °C in CO2, on ...

In the published manuscript “Electrochemical Investigation of the Corrosion of Different Microstructural Phases of X65 Pipeline Steel under Saturated Carbon Dioxide Conditions. Materials 2015, 8, 2635–2649 [1]”, we acknowledge that a contributor (Gaurav R. Joshi) had been omitted from the author list. Alterations are therefore requested to the author list, “Corresponding Author”, “Acknowledgeme...

Abstract To investigate the influence of global plastic deformations on girth weld defect tolerance in pipelines, a parametric finite element model has been developed. This paper provides an experimental validation of the model. It describes the test setup and instrumentation used for the evaluation of plastic strain fields around a notch in a tension loaded non-welded X65 mini wide plate. LVDT...

Near-neutral pH and a low redox potential are considered favorable conditions for immobilizing radionuclides in deep repository systems within clay formations. Cigeo is the future French Industrial Center Geological Disposal high- intermediate-level long-lived radioactive waste, to be built at depth of 500 m Callovian–Oxfordian clay. In-depth knowledge mechanisms kinetics corrosion occurring on...

The stress corrosion cracking behavior of an Incoloy825/X65 bimetallic composite pipe welded joint in wet hydrogen sulfide (H2S) environment was investigated by means the creviced bent beam (CBB) test this study. microstructure, element distribution and crack propagation were analyzed optical microscope (OM), scanning electron (SEM), dispersive spectroscopy (EDS) backscatter diffraction (EBSD)....
