Pipe rust prevention: City, University of London introduces NMR Pipe Protector.

The red rust prevention device "NMR Pipe Protector" can be installed externally on piping without the need for water outage work.

In 2013, the "NMR Pipe Protector" was adopted at City, University of London, a prestigious university in the UK. The air conditioning hot water pipes used SGP (galvanized steel pipes), which led to the leaching of red rust, causing the water to become brown and murky, and there were occurrences of leaks from the pipe joints. It was necessary to take measures against the deterioration of the red rust in the pipes as soon as possible. After the installation of the NMR Pipe Protector, the progression of red rust completely stopped in just two weeks. The iron content in the circulating water within the pipes, which was 3.41 mg/l before the introduction of the NMR Pipe Protector, remarkably decreased to 0.08 mg/l. Theoretically, over 75% of the existing red rust was reduced to black rust by the NMR Pipe Protector. This confirmed the effectiveness of red rust prevention. The black rust formed by the NMR Pipe Protector acts to protect iron from red rust corrosion, and furthermore, black rust is a solid and dense crystal that is 1/10 the volume of red rust, thereby strengthening the pipe's durability. Thanks to the rust prevention effect of the NMR Pipe Protector, the air conditioning hot water pipes at City, University of London can now be used for over 40 years. *For more details, please refer to the PDF document or feel free to contact us.
