| Abstract: | Coke tower is the key equipment in delayed coking unit in oil refinery. High temperature, cyclic temperature fatigue and coking and decoking process may bring about local serious deformation and base metal weld crack on the tower in a long time service. The material selection and structure design scheme was modified by large extent in the revamp. Much success was made after tackling the key technical issues in head forming, transition forging working process, multiplex-plate welding and overall post welding heat treatment. |
