In order to disseminate the existing information on protective systems that have given good performance results, NACE published Document 6H-189 through its technical groups working on coatings for carbon and stainless steels under insulation and corrosion under thermal insulation. This report is unique in its kind and, in the opinion of the authors of this paper, the next step should be the characterization of each of these systems in combination with different insulating materials. Based on NACE Document No. 6H-189, the design of a probe was developed to evaluate, in a salt chamber, the protective coatings which were supposed to work under thermal insulation at high temperatures (30--1,500 C) . This paper describes the results obtained with different combinations of protective coatings (Silicone-Aluminum, Zinc-Rich and Aluminum Metallizing), and thermal insulators (mineral wool, fiber glass and calcium silicate).
