In recent ten years, a number of cracking cases were reported on the in-service high-strength steel spheric tank made of 07MnCrMoVR and 07MnNiCrMoVDR steels (CF-62 steel for short) which were developed in China independently. Based on field survey, actual vessel inspection and failure analysis, it is pointed out that the quality of the steels, the problems existing in design and fabrication process and incompleteness of relevant standards are the major cause of cracking. Recommendations for cracking prevention of the high-strength steel spheric tank made of Chinese CF-62 steel are proposed.
