Frontiers of Mechanical Engineering 2018, Volume 13, Issue 4, Pages 554-562 doi: 10.1007/s11465-018-0513-y
The skirt-to-shell junction weld on coke drums is susceptible to fatigue failure due to severe thermalOne method to decrease junction stress is to add slots near the top of the skirt, thereby reducing theThe most common skirt slot design is thin relative to its circumferential spacing.stress locations in the overall skirt design.It is found that wider skirt slots provide a significant improvement on fatigue life in the weld and
