R. Nabiev, I. Budilov, R. Nasyrov

Аннотация


Damages of oil pipeline’s sections during the maintenance put it often out of operation or cause temporary stops, which as the result involves considerable financial costs. Therefore, the elaboration of efficient methods is an actual task for the estimation of possible consequences of damages and destructions of some sections and oil pipeline as a whole taking into account real defects. Such estimation requires a fulfillment of complex research works, both of destruction mechanisms and kinetics of growth of weary defects and cracks
