Abstract
Due to increasing demand for energy around the world, the prevalence of global megaprojects within the oil and gas industry is increasing. Process pipes, valves and vessels may be manufactured and coated in China or Korea, where labour costs are comparatively low, before being transported to the final project location, such as Western Australia. During the transport and fabrication phase, coated steelwork may spend months or even years exposed to harsh offshore or coastal environments before going into service. This means coatings must be able to provide protection throughout an extensive construction phase, in addition to the in-service lifetime of the steel. This paper examines the demands on high temperature performance coatings both before and once in service. Test methodology and exposure data are reviewed with a focus on how modern aluminium pigmented silicone coatings provide a solution to the corrosion challenges faced in global megaprojects.
Keywords: corrosion, corrosion under insulation, inert multipolymeric matrix (IMM), innovation, productivity, technical, testing.
