| Abstract: | The structure character of coke drums is explained in this paper, the welding procedure of assembly and quality controlling of the coke drums at construction site are introduced. The welding quality is ensured by using backstep welding in longitudinal welds of the shell and by using submerged arc welding in the circumferential welds of the shell. The suitable quality controlling procedure of welding, NDT and heating treatment is given. The manufacturing assembly of the large coke drums is very successful , it shows that the welding procedure and quality controlling procedure are effective. |
| Keywords: | large pressure vessel horizontal welding assembly quality controlling |
