    Fracture Failure Analysis of Oil Pipe

      Graphical Abstract
      • Abstract
    • The fracture reason of an oil pipe was studied by means of metallographic analysis, scanning electron microscopy(SEM), energy disperse spectroscopy(EDS), fluorescence analysis, and so on. The results indicated that the chemical composition of the oil pipe was in accordance with the standard composition of N80 steel. Tubing fracture belongs to the fatigue fracture. Crack origin was pitting holes in the tubing inwall.
