Langues : Américain (ame) Catégories : Anticorrosion Efficience dans l'industrie Lean (production) Revêtements protecteurs Index. décimale : 667.9 Revêtements et enduits Résumé : Material deterioration as result of corrosion is often accepted as unavoidable and it has led to a general lack of awareness of the economic aspects of corrosion. The estimated cost of corrosion as per Hoar committee findings is approximately 3.5 percent of the U.K. GDP. For major asset owners, maintenance of anti-corrosion technology is an integral part of asset design and management to ensure asset integrity within its service life. Defects and failure of assets during service can often be traced back to corrosion deterioration, thus corrosion monitoring and corrosion protection become a vital and integral part of construction and maintenance throughout the life of an asset. Several corrosion protection and monitoring techniques have been developed and these are widely used in the industry with the objective of slowing down the inevitable corrosion-degradation process. The techniques selected will vary depending on the material to be protected and the exposure environment. It is important to note that application and maintenance of corrosion protection such as painting and cathodic protection are time-consuming, costly and have safety implications. In the construction environment, corrosion protection and monitoring are often carried out, not as stand-alone activities, but alongside other work. Therefore, good planning, logistics and engagement with other work trades become even more crucial to ensure that the corrosion-protection processes can be carried out and delivered within time and budget constraints and at the desired quality standard.

UHP waterjetting for new and aged steel / Joao Azevedo in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 34, N° 9 (09/2017)  

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 34, N° 9 (09/2017) . - p. 32-46 Titre : UHP waterjetting for new and aged steel Type de document : texte imprimé Auteurs : Joao Azevedo, Auteur Année de publication : 2017 Article en page(s) : p. 32-46 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Abrasion par jet d'eau Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique. L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1. C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

Meeting the challenges of offshore coating service : methods & materials / Mark B. Dromgool in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 34, N° 9 (09/2017)  

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 34, N° 9 (09/2017) . - p. 48-52 Titre : Meeting the challenges of offshore coating service : methods & materials Type de document : texte imprimé Auteurs : Mark B. Dromgool, Auteur Année de publication : 2017 Article en page(s) : p. 48-52 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Abrasion par jet d'eau Anticorrosion Structures offshore -- Entretien et réparations Structures offshore -- Revêtements protecteurs Surfaces -- Nettoyage Traîtements de surface Index. décimale : 667.9 Revêtements et enduits Résumé : Due to the risks of hydrocarbon fires or explosions and the fragility of some operating equipment and controls, the surface preparation practices employed widely throughout the coatings industry can oftentimes not be used on offshore structures. Too often this means that less productive and/or less effective surface preparation occurs, which can shorten coating system life spans or adds to the frequency of repainting. This article explores methods and materials that have been adopted by a major Australian offshore oil and gas field operator to reliably clean and prepare surfaces for coating. Note de contenu : Fig. 1 : A UHP deck mower in operation. The mist or steam is about the only release during operation as the equipment has its own vacuum recovery system Fig. 2 : A sample area on a FPSO deck blasted with a sponge abrasive after UHP waterjetting Fig. 3 : This shows a zone that has been UHP waterjetted to remove the rust and paint followed by sponge abrasive blasting to SSPC-SP 10 (Sa 2½). Note the small containment used to shroud the sponge-blasting operation and the minor degree of flash rusting En ligne : http://www.paintsquare.com/archive/?fuseaction=view&articleid=6135 Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=29500 [article]
