The effects continue even 15 years after the introduction of the NMR pipe protector.

Verification of the rust prevention effect of apartment water supply pipes: Introduction of a case study after more than 15 years of implementing the rust prevention device "NMR Pipe Protector" inside the piping!

In August 2001, we introduced the "NMR Pipe Protector" to the Co-op Nomura Minami Ishikiri condominium in Wakabayashi Ward, Sendai City, Miyagi Prefecture. After 15 years, an investigation into the deterioration of the piping was conducted. The investigation involved removing the water supply pipes on the secondary side of the elevated water tank and inside the residences, as well as the drainage pipes. It was evaluated that "there was almost no red rust due to internal deterioration of the water supply pipes, and there were no blockages; it was confirmed that the surface had turned black and that pipe rehabilitation had been carried out." The condominium's maintenance director stated during an interview, "Not only the water supply pipes but also the drainage pipes have been extended in their lifespan, and there are no plans for updates in the long-term repair plan." He added, "As the building ages, it will only become more financially challenging in the future, so the benefits of not having to update the water supply pipes are immeasurable." *For more details, please refer to the PDF document or feel free to contact us.
