摘要

Heat distribution system (HDS) pipes and appurtenances are subject to significantly reduced service life when they are located inside manholes with severely corrosive environments. This report documents the demonstration of an innovative coating system for HDS components intended to protect pipes directly, by preventing the corrosion of steel, and indirectly, by reducing heat-related corrosive conditions within manholes. The demonstration was performed at Redstone Arsenal, AL. Field performance of the coating system components was mixed. The primer was straightforward to apply and showed no signs of degradation during the performance period. The topcoat essentially failed shortly after application by turning to powder. The topcoat failure mechanism appears to have been destruction of its acrylic binder by excessive heat, and the result was replicated in the laboratory through an extension of the initial oven tests. At this time it appears that topcoat material did not perform in accordance with the manufacturer's published product data. Because the primer material remains intact and is expected to offer corrosion protection in line with the product data, it represents a significant technology application for corrosion prevention and control. The report includes a return- on-investment calculation based on extension of HDS component service life. Lessons learned are documented.
