FIELD: process engineering.
SUBSTANCE: invention relates to protection of steel against corrosion and may be used for protecting viaducts, bridges etc. Application is made after preparing inhibitor in a container using circulation pump. High-pressure pump inlet branch pie is communicated with inlet branch pipe of permanently IN circulation pump. Simultaneously, required pressure is created at high-pressure pump inlet branch pipe and inhibitor is mixed. Fluid jet in the form of laminated non-volatile flow forced at the rate of, at least, 100 m/s perpendicular to processed surface is formed by nozzle. Thereafter, said surface is rinsed by water and dried by dry air jet.
EFFECT: efficient application.
