| When a natural gas pipeline ruptures, the adjacent automatic line control valves should close quickly to prevent leakage or explosion. The differential pressure set point at each valve position has an essential role for value determining in automatic line control valves action. This study focused on the differential pressure set point values prediction for setting automatic line control valves installed on a gas pipeline. The effect of characteristic parameters such as pipeline operational pressure and pipeline pressure drop rate due to major leak or abrupt rupture was experimentally examined on differential pressure set point. 25 different conditions with double set of typical indicated characteristic factors were selected. The differential pressure for any unique condition was measured in 180s time duration by analyzing the experimental outcomes, statistically. The differential pressure set point increases by changing such as increase in pipeline pressure drop rate or decrease in pipeline operational pressure parameters. Due to applying nitrogen gas instead of natural gas on account of safety claiming, the differential pressure set point results practically can be implemented by adding a 15% safety coefficient. The diagram of differential pressure set point with respect to defined parameters was presented for different values of pipeline operational pressure. | ||
