To prevent pipe red rust, Kumamoto Red Cross Hospital has introduced NMR pipe protectors.

The Kumamoto Red Cross Hospital, which strengthened the piping joints with the black rust effect of the red rust prevention device "NMR Pipe Protector," completely prevented water leaks during the Kumamoto earthquake.

Kumamoto Red Cross Hospital, being a long-established medical institution, faced issues due to the aging of its facilities. One of the significant problems that could not be ignored was the "deterioration of piping due to red rust." One of the issues caused by the deterioration of the air conditioning hot and cold water pipes is "leakage." In a high-level medical facility, leakage can lead to the malfunction of medical equipment and is certainly undesirable from a hygiene perspective. In response, in 2014, the 'NMR Pipe Protector' was introduced as a measure to prevent piping deterioration, and its effectiveness was recognized, leading to its implementation throughout the entire facility. In a water quality survey conducted before the installation of the NMR Pipe Protector, the iron content due to red rust in the hospital's air conditioning hot water was found to be 12.3 mg per liter, indicating significant red rust presence. However, just two weeks after the installation of the NMR Pipe Protector, this amount decreased to 0.07 mg, demonstrating a reduction of approximately 82% in concentration, and proving that the red rust had transformed into insoluble black rust in the water. Not only were we able to protect the medical environment from leakage caused by red rust, but we also became able to allocate more budget to other areas. *For more details, please refer to the PDF document or feel free to contact us.*
