| Abstract: | On the base of the inspection and analysis of the magnetism inspection, metallographic examination, fracture appearance analysis, energy spectrum analysis and X-ray examination etc, it was concluded that the failure of expansion joint was caused by the stress corrosion cracking resulted from hydrogen sulfide. The paper also analyzed the factors of corrosion condition, stress and material. The corresponding prevention measures were suggested. |
