petróleos brasileiros. viii V - ABSTRACT STUDY OF CORROSION OF AISI 1020 STEEL IN CRUDE OIL The chemical attack on crude oil, which contains corrosive compounds such as H2S, CO2, naphthenic acids and salts dissolved in the aqueous phase, combined with effects of varying pH, temperature, flow and pressure, has great influence on the corrosion rate in equipment steel. Given the small number of papers in the literature relating to the study of corrosion of steel in contact with crude…

are subjected to different levels of stress and loading at high temperatures, reducing its lifetime due to the development of defects and corrosion. The Eddy Current Testing (ECT) is a nondestructive testing used to diagnose defects of corrosion and discontinuities in the inner and outer surface of heat exchanger tubes. These tubes are subject to failure by different mechanisms of chemical and mechanical degradation such as fatigue and stress corrosion crack. The ECT signals are…

behauior). Slow cooling and multiple firing of FPDs can promote immediate and delayed porcelain cracking.35 This cracking has been attributed to differences in thermal stresses that develop because of differences in heat transfer rates and overall thermal history. However, it appeares conceivable that alterations in the coefficient of thermal expansion previously discussed may also influence porcelain cracking during normal dental laboratory procedures, Because leucite is considered an…

Maintenance (RCM) concepts. The principles and applications of RCM were documented in Nowlan and Heap's publication, Reliability-Centered Maintenance.1 The work demonstrated that a strong correlation between age and failure rate did not exist and the basic premise of time based maintenance was false for the majority of equipment. Additional studies performed by the Department of Defense (DOD) and several nuclear utilities confirmed Nowlan and Heap's work. 1 F. Stanley Nowlan and…

referido artigo) a parte que se encaixa no escopo do presente trabalho. Antes de mais nada, é importante fazer a seguinte ressalva: em muitas publicações, processos corrosivos em dutos de petróleo e gás são referidos pelo termo “carbon dioxide corrosion”, mesmo que o processo ocorra com a participação de outros agentes corrosivos que não o CO2. A corrosão de aço carbono por CO2 dissolvido se dá pela reação anódica de dissolução do ferro, juntamente com a formação catódica de gás…
