Coke drums are expensive equipment with a long manufacturing cycle, so a realistic and accurate life prediction can save significant time and money. Coke drums are special pressure vessels subjected to large cyclic stresses resulting from thermal distributions that are generated by coke bed interactions and random local flows through the coke bed and around it near the wall.1 It is vital for owners to know as much as possible about the condition of these drums to devise or update plans for operation, inspection, repair and replacement.
