Abstract
A linked coke drum connection to minimize the stresses experienced by the joint between the coke drum and the supporting structure of the coke drum is described. The connection may be attached to a circumferential connection plate attached to the coke drum or directly to the drum. Some embodiments connect to a segmented circumferential connection plate. The connection includes a coke drum link, a connecting link, and a ground link. The links are pivotally connected with connecting pins. As the coke drum is heated and expands, the connecting link pivots outwardly about a point centered in the connecting pin in the ground link.
