Many cases of extensive corrosion have occurred in production tubing, valves, and in flow lines from the wellhead to the processing equipment. The reason for this is that ail and gas from the well contain varying amounts of water, which can be precipitated as a separate phase in contact with the material surface, and that th is water contains gases such as CO2 and possibly H2S, as well as salts. In most cases of severe corrosion, CO2 plays a major role. Uniform corrosion taking place causes 30% failures and other 70% is caused by Iocalized corrosion. Various methods of controlling corrosion are discussed here. Note de contenu : - Petroleum industry

Corrosion rates depend upon various process parameters like pH, temperature, cane juice brix, dissolved oxygen content etc. The losses due to corrosion may lead to unexpected failures, plant breakdown and poor quality & contaminated product. The remedial measures should be taken for the prevention of corrosion like application of protective coatings after the adequate surface preparation or proper selection of the materials of the process equipments.

[article]
Titre : Corrosion and protection of aluminium : Corrosion in non-ferrous metals - Part 2 Type de document : texte imprimé Auteurs : Durgesh Kumar Soni, Auteur ; P. K. Kamani, Auteur Année de publication : 2018 Article en page(s) : p. 117-120 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Aluminium L'aluminium est un élément chimique, de symbole Al et de numéro atomique 13. C’est un métal pauvre, malléable, de couleur argent, qui est remarquable pour sa résistance à l’oxydation13 et sa faible densité. C'est le métal le plus abondant de l'écorce terrestre et le troisième élément le plus abondant après l'oxygène et le silicium ; il représente en moyenne 8 % de la masse des matériaux de la surface solide de notre planète. L'aluminium est trop réactif pour exister à l'état natif dans le milieu naturel : on le trouve au contraire sous forme combinée dans plus de 270 minéraux différents, son minerai principal étant la bauxite, où il est présent sous forme d’oxyde hydraté dont on extrait l’alumine. Il peut aussi être extrait de la néphéline, de la leucite, de la sillimanite, de l'andalousite et de la muscovite.
L'aluminium métallique est très oxydable, mais est immédiatement passivé par une fine couche d'alumine Al2O3 imperméable de quelques micromètres d'épaisseur qui protège la masse métallique de la corrosion. On parle de protection cinétique, par opposition à une protection thermodynamique, car l’aluminium reste en tout état de cause très sensible à l'oxydation. Cette résistance à la corrosion et sa remarquable légèreté en ont fait un matériau très utilisé industriellement.
L'aluminium est un produit industriel important, sous forme pure ou alliée, notamment dans l'aéronautique, les transports et la construction. Sa nature réactive en fait également un catalyseur et un additif dans l'industrie chimique ; il est ainsi utilisé pour accroître la puissance explosive du nitrate d'ammonium.

Corrosion
Métaux -- Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : Corrosion is normally observed on iron and steel surfaces in our day to day life in the form of brown oxide layer of iron. When it comes to the other non ferrous metals, generally the extent of corrosion is less as compared to ferrous metals. Apart from ferrous metals, aluminium is one of the most produced metals worldwide because of its numerous beneficial properties. Earlier aluminium was not in very much use because of the difficulties faced in its extraction. By the end of 19th century the electrolytic reduction of aluminum oxide suggested by Hall & Heroult made the extraction of aluminium very easy and this method was accepted globally. The reason behind the large usage of aluminium are its very useful properties like :
1. Light weight and electrical conductivity e.g., applications in eleçtrical industry and aircraft manufacturing.
2. Wide range of strengths and ease of fabrication e.g., application in automobile industry. Almost all engine parts are made of aluminium by casting in various chapes.
3. Corrosion resistant, non-toxic, recyclable etc.
But corrosion of aluminium also takes place as it is the Iaw of nature. When aluminium surfaces are exposed to atmosphere, a thin invisible layer of aluminium oxide is formed on its surface which protects it from further corrosion : High corrosion resistance of aluminium is due to its self protecting characteristic.Note de contenu : - ALUMINIUM OXIDE

Titre : Corrosion due to microorganisms Type de document : texte imprimé Auteurs : Vinay Kumar Pataskar, Auteur ; Durgesh Kumar Soni, Auteur Année de publication : 2017 Article en page(s) : p. 116-121 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Biodégradation
Corrosion microbienneIndex. décimale : 620.11 Matériaux (propriétés, résistance) Résumé : Corrosion due to microorganisms is also known as biocorrosion or Microbiologically Influenced Corrosion (MIC). There are several types of microorganisms present in environnent that cannot be seen individuatly with the unaided human eye like bacteria, archaea, fungi etc., which are responsible for corrosion of metals via electrochemical mechanism and deterioration of non-metallic materials. The biocorrosion takes place due to the fixation of bacteria, release of metabolites and formation of biofilms that induce or accelerate the corrosion process. This type of corrosion takes the most severe form in soils, saline environment and humid environment. It is estimated that about 20% of all damages caused by corrosion are influenced by microorganisms ; hence it is very important to understand the basic mechanism of microbial corrosion in order to minimize the fosses and accidents due to corrosion in various industries. This review describes the types of microorganisms which are responsible for bio corrosion and the mechanism behind this corrosion.
