operational documentation and the results of ground technical diagnostics and laboratory
studies. The probability of corrosion cracking on sections of three main gas pipelines of
Ukraine is estimated. It is shown that in regions that are identified as potentially corrosive
dangerous, failures due to corrosion cracking were detected. It is confirmed that the
developed methodology allows to determine the regions of gas pipelines of increased
corrosion danger quite accurately.
The results of the work were used in the development of SOU 60.3-30019801-070,
DSTU N B A.3.1-29, changes No. 1 to DSTU 4219.
Key words: main gas pipeline, pipe steel, protective coatings, stress corrosion
cracking, comprehensive anti-corrosion protection, cathodic protection, slow strain rate
test method, potentiometry, fractography.
