    • Abstract
  • Macro and micro morphology of cracks in the end of the N80Q oil casing were observed and the mechanical properties and chemical composition of the oil caing were analysed, and the causes of cracks generation were found. The results show that the cracks generated during perforation and hot rolling, and the reasons of cracks generation were the unqualified hot rolling process and nonumiform heating temperature for tube blank.
