Water supply pipe rust and leakage prevention measures for Hotel #HO.

Case study of introducing NMR pipe protectors into hotel water supply piping.

At a certain hotel, #HO, when it was 25 years old, significant red rust corrosion had progressed in the vinyl-lined steel water supply pipes, raising concerns about leaks from the joints. Therefore, a red rust prevention and pipe longevity device called "NMR Pipe Protector" was installed. Before installing the NMR Pipe Protector, a white filter was attached to the water supply faucet, and after running water for five days, the filter turned brown due to red rust generated inside the water supply pipes, revealing that the iron content captured was 11 mg/l, indicating that the red rust corrosion in the pipes was quite advanced. One month after the installation of the NMR Pipe Protector, a white filter was attached at the same location and under the same conditions as before installation, and the captured iron content significantly decreased to 1.3 mg/l. This demonstrated that the red rust inside the pipes had transformed into black rust, which does not dissolve in water. If the NMR Pipe Protector continues to be used, all red rust inside the pipes will change to black rust, and it has been verified that the cost will be less than one-fifth of the pipe replacement work, allowing the pipes to last until the building's lifespan. Naturally, leaks will also be completely prevented.
