[NMR Pipe Protector Verification Results] Palace of Westminster
The new occurrence of red rust inside the piping has completely stopped, and the existing red rust has turned into black rust!
The Palace of Westminster is currently used as the UK Parliament and is one of the most famous buildings in the UK. It is located on the banks of the River Thames in central London and is a building over 150 years old that was rebuilt around 1860. In one of the several buildings (the Guard Room), the air conditioning hot water piping was severely corroded due to red rust. To prevent the occurrence of new red rust in this piping system, one "NMR Pipe Protector PT-75DS" was installed in the air conditioning hot water piping on the secondary side of the boiler. The iron content in the water before the installation of the NMR Pipe Protector was 3.9 mg/l, but it decreased to 2.38 mg/l 34 days after installation. It was confirmed that 59 days after installation, the iron content in the water had decreased to 1.48 mg/l, which is less than half of the pre-installation value. This result demonstrated that the occurrence of new red rust in the piping had completely stopped, and the existing red rust had turned into black rust, which does not dissolve in water and protects the piping with a corrosion-resistant layer. With the installation of the NMR Pipe Protector, the air conditioning hot water piping can now be used semi-permanently as long as the building remains standing.
