“…It was shown that the transition to the transgranular crack growth path occurs at a depth of about 30 μm. At the same time, the trigger of such a transition is the emergence of a triple grain junction in the growth path, which consists of boundaries with low susceptibility to SCC [10].…”

The work describes the features of stress corrosion cracking (SCC) on Russian gas pipelines. The influence of metal parameters of pipelines on the propagation of SCC is described. The main diagnostic features of SCC used for identification of this type of fracture, the stages of crack growth and the effect of microstructural metal parameters on their propagation are described. Accounting methods for main features crack initiation and growth in order to improve the resistance of the main pipelines metal to SCC are proposed

“…The gas phase often contains a certain amount of carbon dioxide and hydrogen sulfide [4]. These gases, dissolving in the aqueous phase, have a strong corrosive effect on the walls of pipes and other metal equipment [5][6][7][8][9]. In addition, oil fluid always contains mechanical impurities in the form of sand, clay, rust and precipitated particles of mineral salts of magnesium and calcium, the solubility of which decreases with decreasing solution temperature [10].…”

The increase in the corrosiveness of the produced fluid forces to reconsider the attitude towards the assessment of the serviceability and reliability of oil pipes, paying attention to the problems of increasing their corrosion resistance. The paper analyses environmental impact on pipeline made of 9MnSi5 steel after 12 months of operation in the oilfield to assess the residual life of pipeline and determine safe operating conditions. It was found that corrosion damage developed according to the mechanisms of general, pitting corrosion and stress corrosion cracking. Metallographic study has shown cracks of stress corrosion cracking that developed in environments containing carbon dioxide and hydrogen sulfide. Accelerated method of stress corrosion cracking resistance testing was implemented that allows to understand the tendency of steel to this type of cracking and gives a conclusion about the danger of brittle fracture of the pipeline.
