Commercial facilities within the housing complex Air conditioning chilled and hot water piping
Effect verification of red rust turning into black rust.
This facility has been in operation for 22 years, and significant corrosion has occurred within the piping, leading to the necessity for pipe replacement due to leaks. However, it was impossible to carry out water outage work because it supplies chilled and hot water to four buildings, including commercial facilities within a large-scale complex. As a countermeasure, we installed the pipe rehabilitation device "NMR Pipe Protector." After installation, there have been no occurrences of leaks, and regular mass analysis results of the black rust in the pipes have demonstrated that red rust is being prevented and pipe rehabilitation through black rust formation has been proven. The amount of black rust before the installation of the "NMR Pipe Protector" was 2.2%, which increased to 72.9% after 12 months and 91.7% after 45 months, proving the anti-rust effect within the pipes. If we continue to use the "NMR Pipe Protector" in the future, pipe replacement will not be necessary as long as external corrosion does not occur.
