Aerial Robotic Systems: A Novel Approach to Safe Coating Inspection at Heights

by Jamie Branch, Apellix

Aerial robotic technology offers a novel approach to obtaining coating inspection data more efficiently, while reducing an inspector’s occupational exposure to dangerous heights. This article addresses the benefits and limitations of utilizing aerial robotic systems as a viable means of coating inspection.


Qualification Tests for High-Temperature FBE Coatings

by Hassan Al-Sagour and Mana Al-Mansour, Saudi Aramco

As deeper gas wells have been discovered, gas is produced at higher temperatures than before. As a result, the need for higher glass transition temperature (Tg) coatings has emerged, as conventional FBE coatings can-not perform at these higher temperatures, especially in gas flow lines. This article addresses the qualification test methods used to evaluate four different FBE coatings for a maximum operating temperature of 140 C in immersion conditions.


The Effect of Surface Preparation Grades of Weld Seam on Coating Performance

by Sang-Moon Shin, Chung-Seo Park, Seung-Gon Choo, Eun-Ha Song and Han-Jin Bae, Hyundai Heavy Industries

According to the international surface prepa-ration standard for welds, preparation grades before paint application are divided into three levels. These grades are described with rough qualitative representations in-stead of with descriptions of surface treat-ment methods or measurable conditions. In this article, coating thickness and the corro-sion resistance and crack tendency of coated films on welds were evaluated for the grind-ing range in five levels from mild to severe.
