Installed to prevent red rust in the hot water piping! Existing red rust transforms into black rust, which is inert and does not dissolve in water.
Shepperton Film Studios (Hotel) is a historic filming studio located in Surrey, on the outskirts of London. The first building was constructed in 1689, and after suffering a fire, it was rebuilt in 1902 and later renovated in 1936 to serve as a hotel for film actors. There was an issue with red rust in the plumbing, but plumbing work could not be done as it would affect the appearance of the building, which is registered as a Grade II cultural heritage site. Therefore, the NMR Pipe Protector PT-30DS was installed in the hot water plumbing to prevent red rust without affecting the building's exterior. In the men's restroom, where galvanized steel pipes are used, the iron content in the water of the hot water plumbing was 20 mg/l before the installation of the NMR Pipe Protector, but it decreased to 0.37 mg/l after 10 weeks of installation. In the first-floor kitchen, the iron content reduced from 14.5 mg/l before installation to 0.386 mg/l after 10 weeks. From the above, it can be concluded that the occurrence of new red rust in the hot water plumbing has been completely prevented, and the existing red rust has transformed into black rust, which is passive and insoluble in water, thereby proving the rust prevention effectiveness of the NMR Pipe Protector.
