Red rust is converted into black rust with one-tenth the volume! A case where the red rust problem was solved by implementing it for less than one-twentieth of the cost.

This property is 12 years old and uses vinyl-lined steel pipes (VLP) for the water supply pipe joints. The estimated cost for future renovation work to replace them with stainless steel pipes as a measure against future red rust blockage is expected to exceed 100 million yen per building. Additionally, when measuring the red rust blockage rate at the dissimilar metal joints of the kitchen water supply pipes in two units, the rates were found to be 77.5% and 37.3%. By introducing the "NMR Pipe Protector" at a cost of less than one-twentieth of that, the red rust issue was resolved. After 12 months of installation, the red rust blockage rates significantly decreased to 60.0% and 31.0%, and prevention of red rust and the occurrence of black rust were confirmed. [Effects After Installation] - After 12 months of installation, the red rust blockage rates significantly decreased to 60.0% and 31.0%, confirming the prevention of red rust and the occurrence of black rust. - After 27 months of installation, it was confirmed that the red rust had transformed into black rust, with a volume reduction to one-tenth, showing rates of 58.5% and 23.3%. *For more details, please refer to the PDF document or feel free to contact us.
