[NMR Pipe Protector Verification Results] Moseley Hospital (NHS)

Prevent red rust and leaks in the hot water piping of Moseley Hospital!

Moseley Hospital has two independent hot water systems: one connected to the storage tank and the other connected to the hot water header, with galvanized steel pipes used in the hot water piping. As a result, NMR pipe protectors were installed in the storage tank piping and the hot water header piping to prevent red rust corrosion and leaks in both hot water systems. Water samples were taken from the hot water piping at five locations, and the average iron content in the water was calculated. Before the installation of the NMR pipe protectors, the average value was 13.824 mg/l. After 15 weeks of installation, it decreased to 1.3882 mg/l; after 31 weeks, it further decreased to 0.4762 mg/l; and after 49 weeks, it reached 0.3428 mg/l, showing a significant reduction. This result demonstrated that the NMR pipe protectors prevented the formation of new red rust within the pipes and reduced existing red rust to black rust, which is insoluble in water and has a volume that is one-tenth of that of red rust. It has been proven that by continuing to install NMR pipe protectors, the hot water piping will transform 100% of the red rust within the pipes into black rust, thereby extending the lifespan of the building.
