The reasons of emergency situations for the long-term operated industrial pipelines were presented. It was revealed that the greatest risk of accidents at these objects is related to longitudinal destruction, which can occur both in the main metal pipes and in the weld zone, due to the formation of corrosive “fistulas” and “guillotine” ruptures. Industrial gas pipelines are objects of high danger. In case of the gas pipeline failure, there is a shock wave, which is one of affecting factors.
The conditional probability of ignition of emergency emissions of hydrocarbon energy carriers was determined, considering the location of ignition sources. The probit-functions by the thermal effect on people were determined. The determination method of emergency gas losses in case of pipeline rupture was developed. A comparative analysis of gas mass flux at pipeline rupture was performed, depending on the pipeline diameter, initial pressure, time and distance from the point of pipe damage.
