     · The third example is shown in Fig. 17.3 illustrating a pipe coated with inorganic zinc (IOZ)–rich primer that had been under insulation running at less than 93°C (200°F). The worst part of the corrosion was found in temperatures between 71 and 82°C (160–180°F). The key issue in this case was the incorrect specification of IOZ silicate for use in this temperature range under insulation.
