A statistical failure distribution and lifetime assessment of the hsla steel plates in H2S containing environments

Corrosion behaviour of oil well casing steel in H2S saturated NACE solution

“…[11][12][13] The diffused hydrogen may cause a number of problems including: hydrogen induced cracking, sulphide stress corrosion cracking as well as hydrogen embrittlement. [3][4][5][6] Thus it is reasonable to expect the corrosion films to influence the behaviour of H 2 S damage.…”

“…H 2 S damage has been believed to be a major problem in oil and gas industry so that the failure of tubular products in H 2 S containing environments has been extensively investigated. [2][3][4][5][6][7][8][9][10][11][12][13] Especially, the mechanical properties of steels in H 2 S saturated solution were widely studied by Tsay's group, [4][5][6][7][8] who found that aging treatment and grain size greatly influence the susceptibility of hydrogen embrittlement and sulphide stress corrosion cracking. In the meanwhile, the effects of chemical compositions of high strength steels on the sulphide stress corrosion cracking resistance were also investigated by some researchers.…”

“…9,10 On the other hand, the corrosion characteristics and mechanisms of steel in H 2 S saturated solution were further explored. [11][12][13] It is generally accepted that hydrogen sulphide corrosion, sulphide stress corrosion cracking and hydrogen induced cracking are associated with H 2 S damage.…”

“…It is accepted that hydrogen sulphide can react with steels to produce iron sulphide corrosion product films, supported by hydrogen evolution as the cathodic reaction; under these conditions, a fraction of hydrogen atoms diffuses into the steels. [11][12][13] The diffused hydrogen may cause a number of problems including: hydrogen induced cracking, sulphide stress corrosion cracking as well as hydrogen embrittlement. [3][4][5][6] Thus it is reasonable to expect the corrosion films to influence the behaviour of H 2 S damage.…”

Mecanismo de corrosión de acero al carbono en una solución amortiguada de ácido acético, cloruros y H2S: modificación por la presencia de inhibidores de corrosión

“…Siendo ya una realidad, el planteamiento del estudio comprendió desde la determinación del mecanismo de corrosión en los medios amargos sintéticos, utilizados normalmente para las evaluaciones de velocidades de corrosión de diversos materiales metálicos, hasta la comparación del mecanismo de corrosión llevado a cabo en sistemas reales típicos de las plantas de refinación. Dentro de los ambientes corrosivos sintéticos seleccionados, dado que su composición es muy similar a los ambientes reales, se encuentra la salmuera ácida del método NACE TM 0177 (pH amortiguado a 3.5 con una composición de 5 % NaCl, 0.23 % HAc y 0.4 % NaAc, porcentaje en peso); la cual ha sido utilizada principalmente para la evaluación del proceso de ampollamiento por hidrógeno [27,28,29,30,31], y la corrosión bajo tensión o por la presencia de H 2 S [32,33,34,35,36,37,38,39,40], de materiales metálicos en desarrollo y de uso común en la industria del petróleo.…”
