[NMR Pipe Protector Verification Results] Kawanishi City Kushi Elementary School
Red rust prevention device for piping 'NMR Pipe Protector'
Proven rust prevention effect in water quality test one week after installation!
This property is a 29-year-old building that originally used galvanized steel pipes (SGP) for its plumbing at the time of completion, but over the years, it has been updated to use vinyl-lined steel pipes (VLP). However, due to the building's structure, the plumbing inside the framework remains galvanized steel pipes (SGP), which has led to the occurrence of red water due to corrosion. To address the red water issue in the water supply pipes and to protect the plumbing and extend its lifespan, an NMR Pipe Protector was installed. The NMR Pipe Protector costs less than one-tenth of traditional plumbing renovation work and can rehabilitate the pipes by preventing red rust from flowing out and converting it to black rust. In water quality tests conducted before the installation of the NMR Pipe Protector, the iron ion concentration was 0.3 mg/l. However, about five weeks after the installation, it decreased to 0.01 mg/l, which is one-thirtieth of the original level, resolving the red water issue. Additionally, an endoscopic investigation revealed that the rate of blockage due to red rust in the pipes improved by more than 10% after one year and three months. These findings confirm that the rust prevention effects of the NMR Pipe Protector and the rehabilitation effect of converting red rust to black rust continue to persist.
