Measures to prevent red water and leaks in the water supply piping of Legend Hotel Saigon.

Case study of introducing NMR pipe protectors for preventing red rust and extending the lifespan of hotel water supply piping.

The Legend Hotel Saigon is a building that is 7 years old and used galvanized steel pipes (SGP) for its water supply piping. Due to the high sulfur content in the water supplied by Ho Chi Minh City, red rust corrosion in the hotel's water supply pipes progressed very quickly, resulting in red water coming from the faucets in guest rooms within 6 to 7 years after completion. There were also concerns about potential leaks in the future. To address the red water issue caused by red rust in the water supply pipes, a pipe replacement was planned, but it was costly and required a water outage, which would necessitate halting hotel operations. Therefore, a rust prevention and pipe longevity device called the "NMR Pipe Protector," which does not require a water outage, was installed by a major Japanese general contractor. Before the installation of the NMR Pipe Protector, very dark red water due to red rust was coming from the faucets, but 1.5 months after the installation, the water became almost clear, and complaints from the hotel ceased. The NMR Pipe Protector has stopped the progression of new red rust, and it has been proven that the existing red rust in the pipes has transformed into inert black rust that does not dissolve in water.
