FIELD: thermal power engineering, method is used in systems of ball clearing of heat-exchangers pipes cooled by sea water or highly mineralized water. SUBSTANCE: to prevent corrosion in process of heat-exchanger clearing, flexible material porous balls with flash are preliminary impregnated with corrosion inhibitor and then passed through cleared pipes. Due to microporous structure of flash inhibitor washing out of balls is exercised slowly, that decreases consumption of reactant. Saturated solution of iron sulfate or mixture of saturated solution of iron sulfate and 0.02 - 1.00 weight % of trilon B solution under pH 1.5 - 2.0. EFFECT: improved quality of corrosion prevention of heat-exchangers pipes inner surface. 4 cl
