[NMR Pipe Protector Verification Results] Hospital #A

In one year, a total of four units were installed for the water supply and hot water supply piping, in addition to the air conditioning 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, the deterioration due to red rust has progressed significantly. To prevent future leaks, we installed a red rust prevention pipe extension device called the "NMR Pipe Protector." Before installation, we sampled the circulating air conditioning hot water, and the total iron content in the water was found to be 130 mg/l due to red rust, indicating severe corrosion within the pipes. Two weeks after the installation of our product, the total iron content in the air conditioning hot water was significantly reduced to 4.6 mg/l. Furthermore, four weeks after installation, the total iron content was measured at 2.7 mg/l, a reduction to 1/50 of the initial value. The progression of new red rust within the pipes was completely halted, and the existing red rust had transformed into an insoluble form in water, changing into black rust with a volume reduction to one-tenth.
