Considering the application context of multi-material pipes in reactors mentioned earlier, there is a possibility of conflicts when corrosion inhibitors used for different material pipes are combined, and not all scenarios allow for direct compatibility. I. Core risks of conflicts: Antagonism between pharmaceutical components – The chemical mechanisms of specialized corrosion inhibitors for different materials vary greatly. For example, when an anionic organic phosphonate corrosion inhibitor used for carbon steel is mixed directly with a cationic specialized corrosion inhibitor for copper alloys, a reaction may occur, resulting in the formation of flocculent precipitates that undermine the protective effects of each inhibitor. These precipitates can also adhere to the pipe walls, forming secondary scale layers that trigger under-scale corrosion. Interference between protective films: If the passivation film stabilizers used for stainless steel, the adsorptive corrosion inhibition films of Monel alloys, and the precipitation-type corrosion inhibition films of carbon steel are not compatible with each other, it can lead to the failure of the protective layers on certain materials, thereby exacerbating local corrosion. Special risks in nuclear-grade environments: The high radiation and high temperatures inside the reactor accelerate the decomposition of incompatible chemicals, resulting in unknown corrosive by-products that threaten the operational safety of nuclear-grade pipelines. II. Feasible solutions for safe mixing: Prioritize the use of composite nuclear-grade corrosion inhibitors that are compatible with multiple metals; such formulations should contain specialized components suitable for different materials such as carbon steel, stainless steel, and copper alloys. Compatibility tests should be conducted in advance to avoid any conflicts between the various components. It is prohibited to directly mix and apply corrosion inhibitors of different brands and formulations that are designed for use with a single material. If it is necessary to change the chemical used, the pipeline system must first be thoroughly flushed to remove any remaining old chemical before the new one can be added. Before mixing, small-scale bench tests must be conducted to simulate the actual operating conditions of the reactor, in order to observe the stability of the mixture after the chemicals are combined and its impact on the corrosion rate of various materials. Only after confirming that there are no abnormalities can it be put into use officially.
