GUERRA CARVALLO, Claver Hugo. Selecting painting systems for atmospheric corrosion control in an oil field located on the north coast of Peru. Rev. Soc. Quím. Perú [online]. 2014, vol.80, n.3, pp.192-201. ISSN 1810-634X.

The need to preserve the mechanical integrity of the oil facilities affected by the atmospheric corrosion leads to study atmospheric corrosion and categorize according to industry standards such as ISO 9223 Corrosion of metals and alloys - corrosivity of atmospheres - clasification. The oil field, scenary of this study, is located on the north coast of Peru, bounded on the west by the Pacific ocean, this geographical condition that makes it susceptible to severe atmospheric corrosion. An atmospheric corrosion study over steel AISI 1020 specimenes permited characterize the environmental corrosivity category 4 to nearby sea and category 2 in other areas. From this study the operator Oil Company opted for run a field study to select the propers paint systems.

Palavras-chave : Atmospheric corrosion rate; corrosion specimens; relative humidity; chlorides in the atmosphere.
