摘要
This paper briefly describes the characteristics of CF-62 steel material,explains the stress corrosion mechanisms,restriction factors and makes a comprehensive stress analysis for spherical tank,from which,the medium critical pressure is derived.Based upon the relationship between steel hardness and critical value of H 2S concentration which causes stress corrosion,the safety control conditions are developed,while countermeasures of general spherical tank are presented.
