... April 16, 2015. Assoc. Editor: Hardayal S. Mehta. 01 05 2012 01 03 2015 16 04 2015 The second analysis examined the responses of the base and clad material combinations during quenching stage of coke drum operation. In this case, the combinations of SA-302-C as the base material...

...Zhen Li; Zhou Xue; Xu Wang; Fenkun Li It is generally known that delayed coke drums are operated under severe conditions by cyclic heating and quenching operation. It makes them susceptible to thermal fatigue. Therefore, fatigue failures have been identified in the skirt to shell junctures...

...Masaaki Oka; Himsar Ambarita; Masashi Daimaruya; Hiroyuki Fujiki In spite of the fact that coke drums are subjected to cyclic thermal and mechanical loads, generally, they are not designed for cyclic loads. Thus, their operational life is much shorter than other pressure equipment in refineries...

...Feng Ju; John Aumuller; Zihui Xia; Pierre Du Plessis Coke drums are critical equipment in the petroleum industry. The failure modes of coke drums include excessive bulging deformation and fatigue cracking. The elastic-plastic behavior of a coke drum, subjected to both thermal and mechanical...

...Z. H. Ning; R. H. Liu; S. Q. Huang; X. S. Lu Craze cracking and clad disbonding typically occur in cladding due to thermomechanical cycling and high property mismatch between dissimilar materials in a coke drum. The thermoelasticity problem in a coke drum with cladding is assumed quasi-static...

...Zihui Xia; Feng Ju; Pierre Du Plessis Coke drums experience severe thermal and mechanical loadings during operation, and the reliability and safety of the coke drums are critical to the industry. The objective of this study is to analyze temperature and stress of the coke drum for a complete...
