... of structural failure. Based on this, a long-term service carbon steel coke drum was used as the research object and a method was proposed to evaluate the universality of the bulged coke drums in this paper. The details are as follows: firstly, the deformed coke drum was processed into a finite element...

... Abstract Weld overlay is a repair method that has been used over the last 10 years to limit the growth of bulges and to extend the remaining life of delayed coking drums. Different refinery operators have used varied approaches, ranging from localized patches on specific regions of concern...

... Abstract In recent years the understanding of the relationship between drum damage and bulge sharpness has improved significantly. The authors of this paper developed a new parameter called bulge sharpness and have previously shown the relationship between sharpness and observed damage. Further...

... Abstract Laser mapping is a well-accepted technique for obtaining surface profiles of coke drum walls to identify bulges. The resulting data is used to track and trend vessel distortions and mapped to illustrate the shape of the vessel from a base radius and or previous inspection. Monitoring...
