Abstract:

[Truncated abstract] Corrosion of steel structures caused by sulphide is a common engineering problem encountered by many industries, such as the petroleum, chemical processing, mining and mineral processing industries. The control of sulphide corrosion is still a controversial topic among corrosion engineers. There is an absence of guideline for a reliable acceptable limit of sulphide level in service and each processing industry has its own empirical values. Selection of inhibitors in the sulphide environment depends on laboratory testing before its actual application in pipelines and reacti

Abstract:

Pits have been observed to initiate at certain inclusions in stainless steel, which affect the composition and properties of the passive film in that region. In this thesis, the VG MA500 high resolution scanning Auger microscope associated with Link EDX is used to investigate the surface chemistry of inclusion groups in stainless steel 316 relative to the bulk composition, before and after exposure to sodium chloride solution. The work demonstrates that careful control of experimental conditions allows the progress of initiation of pits to be observed systematically. The role of inclusions as

Durante a exploração de petróleo offshore (fora da costa), a injeção de água do mar no processo de recuperação secundária de petróleo, ocasiona a produção de sulfeto de hidrogênio (H2S) pela presença das bactérias redutoras de sulfato (BRS), que reduzem o sulfato presente na água em sulfeto. A produção intensiva de H2S tem sido um dos maiores problemas das indústrias petrolíferas, pois constitui-se uma das principais causas de corrosão em linhas de produção (tubulações), equipamentos e tanques metálicos.

Ce travail de doctorat concerne le stockage des déchets radioactifs à vie longue et haute activité en site géologique profond. Dans le concept actuellement retenu par l’Andra (Agence nationale pour la gestion des déchets radioactifs), c’est une enveloppe en acier non allié, appelée « surconteneur », qui sera au contact de l’environnement. Dans les conditions anoxiques où se retrouvera l’acier après une période initiale relativement courte, des vitesses de corrosion très faibles sont attendues, ce qui garantirait l’intégrité du surconteneur pour des millénaires.

Abstract:

In the petrochemical industry, carbon steels exposed to H2S environments may be susceptible to stress-corrosion cracking. A tensile residual stress and high hardness increases the risk of cracking in H2S environments. NACE SP 0472 limits weld metal hardness to 210 HV10 (200 HB) and heat-affected zone hardness to 250 HV10 to prevent stress-corrosion cracking of carbon steel welds in H2S. The hardness is controlled by the weld thermal cycle or by a post-weld heat treatment. In this project, the effect of hardness on the susceptibility to stress-corrosion cracking was investigated by increasing e

Abstract:

Of the multifarious economic activities of the sulphate-reducing bacteria, the best documented is that of steel corrosion. In the latter part of this century reports of SRB-induced corrosion have come from a variety of industries and much work has been done on practical as well as theoretical aspects of the problem. Despite this the corrosion mechanism has remained indeterminate. The bulk of the argument centres on the role of hydrogenase in the removal of hydrogen from cathodic sites on the steel surface, and whether this is important compared to cathodic depolarisation caused by biogenic fer

The corrosion characteristics of Alloy 625 (UNS 00625, Ni - 22 Cr - 10 Mo) in oxygenated ammoniacal sulphate environments are determined at room temperature and pressure and up to high temperatures and pressures (673 K, 250 bar) commensurate with the process of supercritical water oxidation (SCWO). Electrochemical methods such as linear polarization, potentiodynamic polarization and impedance spectroscopy are used. It is found that the electrochemical and morphological response is dictated by the alloying element Cr and the formation of a Cr(III) oxide. Mo and, to a lesser extent Ni, ar

The doctoral thesis deals with analysis of the ageing of concrete and reinforced concrete pipes in sewage systems. The ageing of the sewage system is caused by several reasons, for example material abrasion, chemical and biological corrosion and subsequent static overload sewer construction. One of the common causes of degradation of sewage systems made from materials bonded with cement sealant is biogenic sulphate corrosion. Due to the corrosion the degradation of the pipe walls accelerates, particularly in upper part of the pipe and reduces planned lifetime of the sewage system. There is pro
