Effect of Elemental Sulfur and Sulfide on the Corrosion Behavior of Cr-Mo Low Alloy Steel for Tubing and Tubular Components in Oil and Gas Industry
The chemical degradation of alloy components in sulfur-containing environments is a major concern in oil and gas production. This paper discusses the effect of elemental sulfur and its simplest anion, sulfide, on the corrosion of Cr-Mo alloy steel at pH 2 and 5 during 10, 20 and 30 h immersion in two different solutions. 4130 Cr-Mo alloy steel is widely used as tubing and tubular components in ...
متن کاملAN INVESTIGATION ON THE PERFORMANCE OF AN IMIDAZOLINE BASED COMMERCIAL CORROSION INHIBITOR ON CO2 CORROSION OF GAS-WELL TUBING STEEL BY EIS TECHNIQUE
Abstract: The performance of an Imidazoline based commercial corrosion inhibitor in CO2 corrosion of a gas-well tubing steel was studied by employing Electrochemical Impedance Spectroscopy (EIS) technique. Inhibitor performance was investigated by means of its efficiency at various concentration and also its behavior at various exposure time. EIS results showed that inhibitor interaction to...
متن کاملThe Effects of Grain Size Distribution and Structure on Mechanical Behavior of Silty Sand
In order to investigate the effects of the grain size distribution and the micro-structure of soils on the mechanical characteristics, some static triaxial compression tests were carried out, and then the relationship of stress-strain and the strength behavior of silty sand were compared among undisturbed samples with different grain size distribution, undisturbed and remolded samples with the ...
متن کاملA MODEL FOR CALCULATING RATES OF GENERAL CORROSION OF CARBON STEEL AND 13%Cr STAINLESS STEEL IN CO2/H2S ENVIRONMENTS
A model has been developed for calculating the rates of general corrosion of carbon steel and 13%Cr steel in aqueous systems containing carbon dioxide, hydrogen sulfide and other components. The model combines a comprehensive thermodynamic speciation module with electrochemical computations based on the mixed-potential theory. The electrochemical calculations recognize the effects of various pa...
متن کاملthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
