[NMR Pipe Protector Verification Results] City, University of London
Complete protection of piping from red rust corrosion through black rust formation! A case that has been usable for over 40 years!
London City University is one of the famous universities located in North London, using SGP for its air conditioning hot water piping. The piping in the building, which is over 40 years old, was experiencing red rust corrosion. To completely protect the piping from red rust corrosion, the "NMR Pipe Protector" was installed. Before installation, the iron content in the water due to red rust was 3.407 mg/l, but two weeks after installation, the iron content decreased to 0.084 mg/l. This demonstrated that our product prevents the occurrence of new red rust in the piping and reduces existing red rust to inert black rust.
