Abstract
The protective coating acts as a layer against erosion, corrosion, and fouling associated with scale deposits. In this study, two laboratory test rigs were installed one for the corrosion rate estimation and another for evaluation of the heat transfer resistance. Three different types of epoxy resin were employed for coating tube surface interiors using different ratios of resin to solvent to produce different coat thicknesses. The results obtained from the corrosion rate and heat transfer resistance measurements showed that the epoxy coating type (a) (ratio of 2: 1 epoxy: solvent ) is efficient in reducing the corrosion rate to 21.110-2 mpy; for example, the efficiency of 92.2% and the heat transfer resistance increased from 12.8810-4 to 18.37*10-4 m2K/W compared to other types of coating.
