[en] Br-82 isotope in the form of paradibromo benzene solution has been injected into oil pipeline of 8 inches in diameter to investigate flow pattern of flushing water inside the pipeline. Two scintillation detectors are put on the pipeline at the distance of 10.52 meter and 39.7 meters respectively from injection point to obtain residence time distribution curves of injected isotope. The flow-rate of flushing water that is calculated by utilizing the mean residence time is 49.7 meter/minute. The model parameter, n, has been analyzed by implementation of tanks-in series model in order to determine the flow pattern of the flushing water inside the pipeline. From this calculation, it is obtained that n = 10 for the first rtd curve and n = 9.17 for the second rtd curve. This result indicates that the characteristic of the flow pattern of flushing water is well mixed flow with quite high degree of turbulence due to the scaling and pit corrosion in the inner wall of the pipe.
