Failure Analysis of P110 Double Male Subjoint Fracture in Offshore Oilfield
In an offshore oilfield,the fracture failure occurred in P110 double male subjoint,and the macro and micro experimental analysis was carried out on the fracture and weld,etc.The fracture morphology and metallographic analysis results revealed that the inner wall fracture of the double male subjoint was judged to be ductile fracture failure and harmful microstructure was generated by welding.The failure cause was further judged to be creep fracture and finally relevant suggestions were put forward.
