FIELD: chemistry.
SUBSTANCE: invention relates to corrosion inhibitors and stress corrosion cracking (SCC) of steel pipelines. The inhibitor contains components at the following ratio, wt %: salts of higher aliphatic acids with alkaline earth metals 5-45; salts of higher aliphatic acids with amines 5-45; substituted trialkoxysilane 25-75.
EFFECT: development of an inhibitor providing, when injected into the primer coat, effective protection of the steel against corrosion and stress corrosion cracking.
