| Abstract: | Stress corrosion emerged in the 1000m 3N TuF50 steel storage sphere may develop a great deal of surface cracks,which need to be controlled to ensure safety in production.Factors effected the development,propagation and stability of the cracks are determined by defect detecting tests and theoretical analysis.This paper has provided a scientific basis for stress corrosion prevention and defects repair. |

| Keywords: | storage sphere crack stress corrosion welding seam |
