Corrosion and deposition in heat exchanger pipes is one of the major problems of a manufacturing unit in the industry. Increasing the concentration of corrosives in a surface sedimentary layer increases the local corrosion due to the temperature of the metal wall beneath the sediment which can cause significant damage. Note that this problem is less common in page converters. There are various types of corrosion in heat exchangers, the most important of which are uniform corrosion, cavity corrosion, galvanic corrosion, groove corrosion, abrasion corrosion and stress corrosion. Using corrosion inhibitors is the best solution for preventing corrosion in heat exchangers. Various inhibitors have been used in heat exchangers, but depending on the material used in heat exchangers, inhibitors such as the family of phosphates, chromates, bicarbonates, azoles, and silicates are used, which perform better than other inhibitors. . In this study, azole and polyphosphate derivatives were used as corrosion inhibitors in heat exchanger environments and spark emission spectroscopy, FTIR, weight loss, TOEFL polarization and electrochemical impedance spectroscopy were used to determine the anti-corrosion properties of corrosion inhibitors. Different sulfate ions and chloride ions and Langelier indices have been investigated. Immersion tests were performed in two different concentration series, including higher values ??of 100 ppm and values ??lower than 30 ppm. Optimal concentrations of two polyphosphate and benzo-triazole inhibitors, which were both economically viable and had acceptable reductions in the rate of corrosion of copper and steel, were used, and the results showed that the concentration of 12 ppm of benzo-thiourea inhibitor was used. Azol with 20 ppm polyphosphate inhibitor is the optimal concentration level for these two inhibitors in the heat exchanger system at different concentrations of chloride and sulfate ions. The inhibition efficiency for copper is about 98% and for steel at concentrations above 99%. For better corrosion control, keeping the pH constant in the neutral range close to 7 can be used, and the use of the Langelier index of 1 for compensatory water also significantly reduces the corrosion rate. Application of these inhibitors increased the uniform corrosion resistance of copper, steel and optimum concentration of the two aforementioned inhibitors.
