The cooling system of the food is one of the main essential systems to maintain food quality in the food processing plant. The using of corrosion inhibitor for the cooling systems is a familiar practice to control the corrosion which is happening due to a different kind of parameters like water quality and the type of materials for the cooling system, in this work, the case of adding corrosion and scale inhibitor to a cooling system containing carbon steel and stainless steel and copper was investigated. The inhibitor was mixed of two materials which are (Sodium Tripolyphosphate as a scale inhibitor and Sodium Polyphosphate as a corrosion inhibitor). The results demonstrate that there is an improvement in reducing the corrosion rate for iron after adding the inhibitor, and the copper ions in the solution reduced if the PH values below 9.5.
