To prevent pipe rust, Tokyo University of Science has introduced the NMR Pipe Protector.

The red rust prevention device "NMR Pipe Protector" prevents the deterioration of piping due to red rust, resulting in significant cost savings.

The Kagurazaka campus of Tokyo University of Science was 26 years old at the time. The water supply pipes were made of PVC-lined steel pipes, and serious red rust blockages had occurred at the joints of the water supply pipes. Before the installation of the NMR Pipe Protector, an inspection of the red rust blockage rate in the toilet water supply piping revealed that the blockage rate was 35%, indicating significant red rust deterioration. After the introduction of the NMR Pipe Protector, a re-inspection was conducted at the same location 10 months later. The results showed that the red rust blockage rate had decreased to 31%, and it was verified that the red rust was gradually changing from a volume of 1/10 of black rust from the surface of the red rust. At Tokyo University of Science, the NMR Pipe Protector was introduced to extend the lifespan of the piping in buildings and facilities that were originally scheduled for replacement in 10 to 15 years.
