The hospital that first validated the "NMR Pipe Protector" - NMRPT.

The first hospital to verify the "NMR Pipe Protector" - NMRPT - was the "Former Medical Center of the Japanese Red Cross Society." In 1999, the water supply pipes of the former medical center, which had been built 24 years earlier, were made of galvanized steel. Red rust had developed inside the water supply pipes, and the water from the tap in the newborn room showed an iron ion concentration of 2.0 mg/l in the morning, significantly exceeding the water quality standard of 0.3 mg/l. As a result, large amounts of water were run before use. To prevent future leaks, one NMR Pipe Protector was installed on the secondary side piping of the elevated water tank. Water was sampled from the tap in the newborn room, located about 150 meters from the elevated water tank, to verify the effectiveness of rust prevention. Measurements of the iron ion concentration in the water at the Tokyo Metropolitan Institute of Public Health showed that before the installation of the NMR Pipe Protector, the level was 2.0 mg/l, but it dropped to 0.48 mg/l two weeks after installation and to 0.27 mg/l six weeks after installation, proving that the NMR Pipe Protector prevented new red rust in the water supply pipes and reduced existing red rust to non-soluble black rust. Because these verification results were beneficial for other Red Cross hospitals, they were introduced in the January 2000 issue of the internal newsletter of the Japanese Red Cross Medical Center to hospitals nationwide.
