Abstract
One tube defects that affect the stress-strain state is ovalisation. To calculate the risk of an
accident with a view ovalisation in this paper we consider the set-fuzzy approach, the main
function of belonging. As the fuzzy parameter selected in-line pressure. Calculated fuzzy value
of the stress state of the pipeline, the risk of counting options. The risk of accident is
considered as the ratio of thresholds for the system and the real, in this case, the real value is
considered a fuzzy number кц , and as a limit -[ кц ]. Thus, the authors propose and
justify an alternative approach to assessing the risk of failure of the linear part of the pipeline
in view of ovalisation, in which the option is in-line pressure is represented as fuzzy numbers.
