[NMR Pipe Protector Verification Results] Hotel Serve Shibuya
Red rust prevention device for piping "NMR Pipe Protector"
Completely prevent water leakage damage from air conditioning piping used in hotels!
At Hotel Serve Shibuya, galvanized steel pipes (SGP) are used for the air conditioning chilled and hot water piping, and there was concern about the deterioration due to red rust and potential leaks from the joints. Therefore, a red rust prevention and leak prevention measure, the "NMR Pipe Protector," was installed. Before the installation of the NMR Pipe Protector, water samples were taken from the air conditioning chilled and hot water piping, revealing that the water was light brown in color and the total iron content was 5.8 mg/l, indicating significant red rust corrosion within the pipes. Two weeks after the installation of the NMR Pipe Protector, the total iron content in the water from the air conditioning chilled and hot water piping significantly decreased to 0.6 mg/l. In water samples taken four weeks after the installation, the water color had become almost transparent, and the total iron content further decreased to 0.5 mg/l. It was proven that new red rust was completely prevented in the air conditioning chilled and hot water piping, and the existing red rust had transformed into passive black rust. Moving forward, if the use of the NMR Pipe Protector continues to prevent external corrosion at Hotel Serve Shibuya, it has been demonstrated that all red rust in the air conditioning chilled and hot water piping will change to black rust, allowing this piping to be extended for the lifespan of the building. Naturally, leaks have been completely prevented thereafter.
