Break out had happened during field hydraulic test of unused line pipe. The observation of failure pipe indicated presence of the pre-damage at the broken portion. We supposed that the damage would have occurred during manufacturing or shipping. From analysis offracture surface and failure section, follow ing facts were revealed<BR>(1) The cracks propagate in wall thickness direction independently of the metal-flow of hot rolling direction.<BR>(2) The crack initiation sites are the external and the internal surfaces of the pipe and the cracks propagate stepwise with smooth fracture surface.<BR>(3) In the fracture surface, many corrosion products are observed and clear striations are locally recognized.<BR>It was concluded that the failure was caused by fatigue crack during shipment. This mechanism was confirmed by the pulsating bending fatigue test of pipes.
