Question

Quizplus · Accepted Answer

Thermal fatigue cracking has been a major problem in coke drum shells due to the cyclic heating and cooling during the coking process. This can lead to thermal stresses that cause cracking. Stress cracking can also occur, but it is typically less of an issue than thermal fatigue cracking. Carburization and sulfide cracking are not common issues in coke drum shells.
