Buckingham Palace was built in 1703 for the Duke of Buckingham and became the royal residence of the British monarch upon the accession of Queen Victoria in 1837. The palace has now 775 rooms and is used as an office and residence of Her Majesty the Queen.
Although some old pipes were replaced, others supplying hot water throughout the palace were kept unchanged, causing problems regarding internal corrosion. In addition, the problems also remained in a central heating system using galvanized steel as pipe material.
To prevent corrosion deterioration and prolong the lifespan of the water systems, the palace installed three NMR Pipetector PT-100DS, PT-50DS and PT-30DS on three water pipes on January 12, 2007.
24 days after installing NMR Pipetector, the Fe content in the domestic hot water was drastically reduced from 2.75 mg/L to 0.018 mg/L, which is much lower than the British standard for drinking water quality 0.2mg/L. The level was kept low at 0.007 mg/L even after 90 days.
The Fe content in the heating water was 16.6 mg/L before installation, which was then drastically reduced to 0.455 mg/L after 24 days.
These results indicate NMR Pipetector immediately terminated the new formation of corrosion inside the pipework and reduced the existing red rust to black rust (magnetite), which does not dissolve in water. NMR Pipetector will now protect inside the pipework from internal corrosion and prolong the lifespan as long as that of the palace.
