Abstract: The O&G production corrosion challenges are not static phenomena. Fluid characteristics change over time, resulting in systems becoming less predictive for corrosion mitigation programs. Thus, carrying out specific studies aimed at understanding the corrosion mechanisms is constant in this sector, especially for offshore environments. Even though, few studies of Leia mais…

Abstract: Occupational exposure to toxic elements can adversely affect health. The current study evaluated blood concentrations of potentially toxic elements (PTE) including As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Sb, Sn, and Zn in formal and informal workers. Additionally, the study investigated the associations between blood PTE concentrations and Leia mais…

Abstract: Internal corrosion is one of the main problems related to the integrity of pipelines. It depends on the type of material used in the manufacture of the tubes and the composition of the fluid. Generally, the material used is carbon steel which, despite having low cost and good weldability, Leia mais…

Resumo: A soldagem por Fricção e mistura linear é um dos processos de soldagem onde não há fusão do material base, de modo que alguns problemas geralmente associados com processos de soldagem são evitados, tais como trincas a quente e porosidades. Este trabalho tem como objetivo avaliar os impactos do Leia mais…
