CORROSION STUDIES
Atmospheric and soil corrosion studies for metallic elements of carbon steel, zinc, copper and aluminum
ATMOSPHERIC AND SOIL CORROSION STUDIES
ATMOSPHERIC CORROSION STUDIES
Studies of atmospheric corrosion in projects for metallic elements of carbon steel, copper and aluminum, depending on the atmospheric conditions of the site and the useful life of the facility. Estimation of the category of atmospheric corrosion from databases and bibliographic sources (temperature, humidity, contamination, SO2 and Cl- deposition rates) and determination of the category of atmospheric corrosion from Wire-on-Bolt and Plate tests with measurement of atmospheric action in-situ according to G116-99 and UNE-EN ISO 9223:2012.
- Definition of the corrosion category
- Definition of galvanizing thickness
- Definition of protective paints
Studies according to current applicable international regulations.
