[NMR Pipe Protector Verification Results] Hospital #A

In one year, a total of four devices were installed in addition to the air conditioning hot water piping, for all water supply and hot water piping!

At Hospital #A, which was built 31 years ago and uses galvanized steel pipes (SGP) for its air conditioning hot water piping, significant deterioration due to red rust has been observed. To prevent future leaks, a red rust prevention piping extension device called "NMR Pipe Protector" has been installed. Before installation, a sample of the circulating air conditioning hot water was taken, revealing a total iron concentration of 130 mg/l due to red rust, indicating severe corrosion within the pipes. Two weeks after the installation of the product, a sample of the air conditioning hot water showed a total iron concentration of 4.6 mg/l, a significant reduction. Furthermore, a sample taken four weeks after installation showed a total iron concentration of 2.7 mg/l, reducing it to 1/50 of the previous level. The progression of new red rust within the pipes has completely stopped, and the existing red rust has transformed into an insoluble black rust with a volume reduced to one-tenth.
