Abstract

The use of pipelines is one of the most important methods of gas transmission. Leakage in gas transmission lines causes financial and life-threatening damages. For this reason, it is very valuable to obtain information such as maximum safe radius of fire, explosion and leakage of materials. This information can play an important role in dealing with accidents in emergencies. In this study, safe privacy for 42-inch gas pipeline was studied using PHAST software version 7.11. The highest amount of radiation is related to the horizontal state and the lowest amount of radiation is related to the vertical state. The vertical direction has the lowest radiation distance from the propagation source, while the horizontal direction at an angle of 45 degrees shows the highest radiation distance from the propagation source. Simulation results showed the lowest radiation outcome for pressurized environments and the most dangerous radiation for hazardous areas. For example, if the ratio of leakage diameter to hole diameter is 0.25 and leakage mode is horizontal. The safety privacy caused by fire for hazardous areas, enclosed environments and pressure environments is 850, 1070 and 1360 meters, respectively.
