| Abstract: | The design of shell for 300kt/a ammonia synthesis reactor was illustrated including material selection,structure of a part of sealing piece and welding state.The structure of the body had the characteristics of multi plate wrapping,forged ring transition between the body and spherical bottom,and bi taper sealing structure tightened with large bolts between the body and the disk cover.SA387 Gr. 12CL2 was adapted for material of internal of the body,SA724 Gr.B for multi plate,SA387 Gr.22CL2 for spherical bottom,and INCONEL 82 for bead welding material of the end of the body. Soft graphite spacers were used in bi taper rings.The detection results showed that the design was economic and feasible. |
