 This study investigated the effect of a chromium layer on the heat transfer in a steel tube during a series of heat impulses. It found that the thicker the chromium layer, the lower the maximum temperature reached by the tube wall. Additionally, it was observed that the temperature of the wall decreased significantly after the first heat impulse, but increased again after the second one. Finally, the study concluded that the temperature of the wall did not exceed 750 degrees Celsius after 7 heat impulses, indicating that the chrome coating would crack if subjected to more heat impulses.
