| Abstract: | Through discussions of the utilizing situation and inspecting circumstances of a spherical container in the paper, its crack producing reason, defect safety and residual life have been analyzed. The crack produced in the spherical container is believed to be hydrogen induced delayed crack. The acceptable crack sizes of the spherical container and safety fatigue life have been given in the paper. |
