| Abstract: | The cause of cracks which appeared on spherical tanks made of localized CF-62 steel was investigation through field investigation,spherical tank assembly and welding,in-service inspection and failure analysis.At the same time the level of residual stress was described.Some suggestions were proposed about perfection of design,fabrication and inspection specifications in relevant standards,which provide references for future fabrication and long-term safe operation of this type of steel. |
