A Study on Stress Corrosion Cracking of X70 Pipeline Steel

Nov 08, 2012 · In this study, electrochemical impedance spectroscopy (EIS) simultaneously with the slow strain rate testing were used to investigate the stress corrosion cracking (SCC) behavior of X70 pipeline steel in high pH bicarbonate solution at different applied potentials. Potentiostatic EIS tests were also conducted at certain times to determine the changes associated with the SCC. Corrosion behavior of X65 pipeline steel:Comparison of Abstract The initial corrosion behavior of X65 pipeline steel subjected to wetdry cyclic exposure and full immersion were investigated to determine the corrosion behavior of X65 pipeline steel in marine splash zone and below the waterline. The scanning electron microscope (SEM) test results indicated that pitting corrosion occurred under wetdry cyclic condition whereas general corrosion

Effects of H 2 S/HS - on Stress Corrosion Cracking

Apr 01, 2017 · The effect of H 2 S/HS-, which simulates the main metabolites of sulfate-reducing bacteria (SRB), on the electrochemical and stress corrosion cracking (SCC) behaviors of X100 steel was investigated in a near-neutral solution. The results showed that different H 2 S/HS-contents mainly affected the cathodic process of X100 electrochemical corrosion. Effects of H2S/HS- on Stress Corrosion Cracking Behavior h The effect of H2S/HS-, which simulates the main metabolites of sulfate-reducing bacteria (SRB), on the electrochemical and stress corrosion cracking (SCC) behaviors of X100 steel was investigated in a near-neutral solution. The results showed that different H2S/HS- contents mainly affected the cathodic process of X100 electrochemical corrosion. Research Progress of Stress Corrosion Cracking Behaviorof Abstract Biofilm is a kind of special microbial aggregates that adheres on the carriers surface and creates an unusual surface condition facilitating the stress corrosion of pipeline steel. In recent years the stress corrosion cracking behavior of pipeline steel under the action of biofilm has been studied as an academic research focus.
