The article discusses the main causes of natural gas leaks and ways to detect them. Data on the volume of natural gas leakage and the nature of damage were obtained at the experimental installation. The objects of experimental research are gas connections to devices, such as: bellows hose made of stainless steel, rubber hose and cap nut of gas connection with varying degrees of tightening. The course of conducting an experimental study of filling a room with natural gas, depending on the degree of damage to the gas supply and its nature, is described. The analysis of the results of the experiment to determine the dependence of the gas flow rate on the type of damage to the gas supply is carried out. The most dangerous types of leaks in the room are determined, graphs of the dependence of gas flow through various damages and methods of their prevention to prevent such situations are constructed.
