FIELD: metallurgy.
SUBSTANCE: invention relates to production of steel fuel-conducting tube with antirust film layer on inner peripheral surface of steel pipe material. Tube material is sampled and classified for having an initial defect exceeding a given threshold value of 150 mcm, or having an initial defect which does not exceed a given threshold value. Initial defect is removed on inner peripheral surface of tube material, having initial defect, not exceeding threshold value, by means of machining by cutting. Surface treatment of inner peripheral surface of tube material is performed.
EFFECT: as a result, corrosion on tube is prevented.
