Alternative for Evaluating Sour Gas Resistance of Low-Alloy Steels and Corrosion-Resistant Alloys

EIS characterization of tantalum and niobium oxide films based on a modification of the point defect model

“…The breakdown of oxide films may be promoted by the formation of molecular hydrogen at the metal-film interface, when a critical condition of pressure is reached. Experimental evidence for this phenomenon has been reported in the literature for different electrochemical interfaces [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

Materials and corrosion trends in offshore and subsea oil and gas production

“…Researchers have found that pitting corrosion appears to be a prerequisite for SCC in production environments, as the conditions that stabilize a pit are similar to those required for SCC. 75,76 Anderko, Sridhar and coworkers have developed a framework that uses the repassivation potential (E RP ) and the corrosion potential (E Corr ) to estimate the likelihood of SCC in sour production environments. [77][78][79] The main assumption is that SCC occurs only in the presence of localized corrosion when the temperature is above the critical pitting temperature and E Corr > E RP .…”

Stress corrosion cracking of 13% Cr martensitic steels in sodium chloride solutions in the presence of thiosulphate

“…A JSCE (Japanese Society of Corrosion Engineering) research group investigated an alternative method to determine the SCC resistance of corrosion resistant alloys and low alloy steels in sour environments [13]. The method basically consisted in substituting TIO for hydrogen sulphide.…”
