| Abstract: | Pipeline pressure is important for leak rate calculation and leak consequence simulation. The experiments were conducted with the leak and gas diffusion testing system, and a Flowmaster model of the testing system was established. The model was proved by experimental data. It showed that the model can be used to predict the pressure response of hole-leak and calculate the stable pressure of pipeline precisely. It can provide theoretical ba- sis for the hole-model to calculate the leak rate accurately. |
