To extend the lifespan of existing piping to match the lifespan of the building, if the red rust occurring inside the pipes can be converted to black rust without flushing it away, the lifespan of the pipes can be prolonged to that of the building. When extending the lifespan of pipes, methods such as pipe cleaning or sandblasting to remove red rust can damage the interior of the pipes, reducing their strength. With our internal red rust prevention device, the 'NMR Pipe Protector,' red rust can be converted to black rust without directly contacting the water inside the pipes. By utilizing NMR (nuclear magnetic resonance), it is possible to prevent the deterioration of red rust inside the pipes and even rehabilitate and strengthen the pipes. It is suitable for preventing red rust in water supply pipes (vinyl-lined steel pipes) and air conditioning hot and cold water pipes (galvanized steel pipes), as well as for the rehabilitation and strengthening of pipes. *For more details, please refer to the PDF materials or feel free to contact us.

On January 12, 2007, in one of the six pump rooms located within Buckingham Palace, only one pump room supplying Her Majesty's room had the 'NMR Pipe Protector' installed for the air conditioning hot water piping and the hot water supply piping. Before the installation of the NMR Pipe Protector, the iron ion concentration in the circulating hot water within the air conditioning hot water piping for Her Majesty's room was measured at 16.6 mg/L, indicating a high iron ion level and a significant presence of red rust within the piping. Subsequently, 24 days after the installation of the NMR Pipe Protector, the iron content in the hot water within the air conditioning hot water piping decreased to 0.455 mg/L. The piping was completely protected from red rust by the NMR Pipe Protector, and the lifespan of the piping was extended, which has been greatly appreciated by those associated with Buckingham Palace for security reasons. *Customer feedback (customer testimonials) and other PDF materials are available for free! *Please feel free to contact us first.

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 of implementation, 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 due to rust, and 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.

The red rust prevention device for piping, "NMR Pipe Protector," has obtained patents and registrations in the United States and major countries around the world after undergoing rigorous patent examinations abroad regarding its practicality and other factors. On February 16, 2004, the first installation in the UK was at Addenbrooke's Hospital, affiliated with the University of Cambridge. The NMR Pipe Protector holds a patent in the UK and established its reliability through presentations at conferences related to "corrosion," leading to its installation upon recommendation from the University of Cambridge. The hot water pipes at Addenbrooke's Hospital experienced leaks due to bacterial corrosion and red rust deterioration just three years after the piping was updated. However, after the installation of the NMR Pipe Protector, red rust in the hot water piping made of galvanized steel was prevented in just 11 days. The iron ion concentration due to red rust in the hot water decreased from 1.07 mg/L before installation to 0.188 mg/L after 11 days, falling below the water quality standard of 0.2 mg/L. The transformation of red rust in the hot water pipes to black rust with a volume reduction to one-tenth confirmed the rust prevention effect of the NMR Pipe Protector.
