Evaluation of Sulfide Stress Corrosion Cracking and Electro-chemical corrosion susceptibility of the ASTM A106 Gr. B steel weldments

摘要

The cause of corrosion failure in various components used petroleum pipeline has been attributed toSulfide Stress Corrosion cracking(SSCC) which is resulting from the combined effects of sulfideenvironments and static tensile stress. Therefore, In this paper, the characteristics of the Sulfide StressCorrosion Cracking(SSCC) of ASTM A106 Gr. B steel weldments were studies under the environment ofH2S solution. And Corrosion characteristics on the ASTM A106 Gr. B steel weldments was electro-chemicallyinvestigated on the base metal, HAZ, weldments, respectively.
