Forecast of gas mass flow rate in case of the industrial pipeline ruptures

Kryvenko G. M., Vozniak L. V.

The causes of emergencies on industrial pipelines are given. Industrial pipelines in oil and gas fields are not safe after a long period of operation. Therefore, the risk of emergency-dangerous defects and the possibility of an explosion on gas pipelines are increased. The greatest risk of accidents on industrial pipelines is associated with longitudinal fractures, which can occur both in the main metal of the pipes and in the zone of welded joints, with the formation of corrosive "fistulas" and "guillotine" ruptures. The conditional probability of ignition of emergency emissions of hydrocarbon energy carriers taking into account the location of ignition sources was determined. A method for determining emergency gas losses at a pipeline rupture was proposed. A comparative analysis for the mass flow rate of a gas at a pipeline rupture, depending on the diameter of the pipeline, the initial pressure, time and distance from the damage to the pipes was carried out.
