Abstract
Since 1991 till the year of 2000 more than 300 serious accidents happened in Russia. The significant part of the accidents at main pipelines was connected with electrochemical corrosion, stress corrosion cracking and microbiological corrosion. System analysis of the accident reasons cannot be given without probabilistic and statistical approach, which assumes that the reason of the accident is the combination of many influencing factors. At the same time usage of the multivariate analysis is quite complicated task due to a large amount of factors, influencing the pipelines accident rate, insufficient statistics and unauthentic documentation of the accident causes.
