| Sumario: | Oil, gas and petrochemical facilities are strategic industry facilities, and their passive defense issues are of high priority in every country. Explosions due to sabotage or aerial bombardments are of the most important factors in considering issues related to passive defense in the abovementioned facilities. In this study, the effect of blast loading on pressure vessels is investigated. In this regard, the results of ConWep method for applying an external blast load, are validated. Then, it is used as the loading method in the study. The results of this study clearly indicate that the vertical pressure vessels are more vulnerable than horizontal and spherical pressure vessels against the blast load. Therefore the use of these types of pressure vessels can reduce safety against potential hazard. The horizontal pressure vessels are more vulnerable than spherical pressure vessels against the blast load. In addition, the body of the pressure vessel shows splendid resistance against external explosions, and the most likely risk scenario is damage to the saddles which results in lateral displacement of the vessel. The following safe scaled distance from explosive sources of pressure vessels in oil and gas facilities offered.Keywords:Pressure VesselHE ExplosionOil and Gas FacilitiesNumerical AnalysisPassive Defense |
