To achieve the goal, this study aims to explore and develop chemically-bonded enamel coating (200-300 \ub5m) for coating uniformity, low surface roughness and high coating efficiency, and corrosion resistance. The objectives will be achieved both experimentally and numerically in the following four research tasks: 1. Optimization of enamel materials for durability, particle distribution, and thermal compatibility with steel; 2. Enameling process for coating uniformity, surface roughness, and efficiency without adverse effect on steel properties; 3. Characterization of enamel-coated pipe for microstructure/porosity, chemical adhesion, and corrosion resistance; and 4. System performance of in-situ, enamel-coated pipelines \u2013 stress distribution under thermal, external and internal pressure, and stress corrosion cracking.119
