FIELD: corrosion protection.
SUBSTANCE: invention relates to the field of protection of metals from corrosion and can be used to protect oilfield equipment and pipelines operated in aggressive environments. The use of 5-substituted 2-amino-1,3,4-thiadiazole of general formula
as an inhibitor of hydrochloric acid corrosion of steel St3 in the concentration range of 50-200 mg/l in 1 M HCl solution is proposed.
EFFECT: new compounds of thiadiazoles have been found, which increase the resistance of steel to corrosion during hydrochloric acid treatment of wells.
