Abstract
Basic concepts for evaluating durability of mains are formulated as problems of the strength and safety of extended constructions under the action of random operational loads and effects. A system of sequential operations resulting in determination of the critical time of exploitation of the pipeline section is constructed. Acceptable values of probability components of potential damage for pipeline sections belonging to three durability classes are given. The choice of the durability criterion of a construction element and conditions of safe operation of a pipeline section from the point of view of durability are considered as one of the fundamental blocks of the algorithm.
