Systematic approach to prediction of the stress corrosion condition of trunk gas pipelines in Russia

摘要

Degradation processes have specific impact on the Russia's gas transmission system reliability. These processes include corrosion of general and local nature, erosional wear of gas pipelines and multiple pipe damages with fracture-like defects, most of which were formed due to the stress-corrosion mechanism. Meanwhile, the development of stress-corrosion defects of all others, which recently caused up to 50% of failures of trunk gas pipelines, can be prevented by means of the developed methods of prediction of this process.
