Water supply pipe rust and leak prevention measures for a certain hotel #HO.
Case study of introducing NMR pipe protectors into hotel water supply piping.
At a certain hotel, #HO, significant red rust corrosion had progressed in the vinyl-lined steel water supply pipes after 25 years of construction, raising concerns about leaks from the joints. Therefore, a rust prevention and pipe longevity device called the "NMR Pipe Protector" was installed. Before the installation of 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 the 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 proved 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, it has been verified that all red rust in the pipes will change to black rust, and the cost will be less than one-fifth of the pipe replacement work, allowing the pipes to be extended for the lifespan of the building. Naturally, leaks will also be completely prevented.
