Protecting the surface of heat supply pipelines from corrosion remains a problem, as corrosion and the formation of a scale layer reduces the thermal conductivity of the metal and the transportation of the coolant. The aim is to study the production of an effective composition of inhibitors for protecting metal surfaces from corrosion. In order to eliminate corrosion of the pipeline surface and ensure the free passage of coolant in heat supply systems, it is necessary to prevent corrosion scale formation by using effective inhibitors and selecting a chemical reagent for cleaning and activating the inner surface of the pipe. To activate the pipe surface, an effective reagent, sulfamic acid, is proposed, which increases the adhesion strength of the inhibitor films and reduces the corrosion rate from 0.104 g/m2 h to 0.010 g/m2 h, as well as metal losses due to corrosion from 0.13•10-2 mm/year to 0.5•10-3 mm/year. After activation of the surface of the sulfoamic acid metals, the solution is regenerated or suggests using a metal sulfonate salt (zinc, copper, calcium) as a fungicide for plant treatment. Through a comprehensive study, an effective composition of sodium silicate and tripolyphosphate was obtained for the formation of a protective film on the surface of a steel sample of activated sulfoamic acid and the optimal time for the formation of a protective film on the surface of a steel sample from a mixture of inhibitors was determined. It is shown that a film based on a mixture of sodium silicate and sodium tripolyphosphate is adsorbed on a surface activated by sulfoamic acids much more strongly than other acids, while the mass of the coated inhibitor film depends on the duration of the deposition process.
