The paper presents the results of the calculation of the safety factor for main gas pipeline sections, taking into account the random nature of the external load and the yield strength (σТ) of the pipes material with various grades. Based on the actual values of the safety factor, the current level of main gas pipelines sections reliability was assessed. The necessity of taking intoaccount the individual laws of yield strength distribution of the material of pipes with various grades used at construction stage of gas pipeline when determining safety class of pipeline section is substantiated.
