Palace of Westminster

Westminster

The Palace of Westminster is one of the most famous buildings in the world. It is located on the North bank of River Thames and was built in the 1860s approximately. One of the buildings had a major problem of internal corrosion in its central heating system.
So, to protect all the central heating systems completely, the Parliament installed one NMR Pipetector PT-75DS installed on a central heating supply pipe on April 12, 2010.

Before the installation, the Fe content in the heating water was 3.9 mg/L. However, after only four days, the Fe content decreased to 2.2 mg/L.

The level decreased continuously, and after 12 weeks, it further decreased to 1.48 mg/L, which is less than half before the installation. It means NMR Pipetector terminated the new formation of corrosion inside the pipework and reduced the existing corrosion into magnetite, which does not dissolve in water. NMR Pipetector will now protect inside the pipework from any internal corrosion so that it can be used until the life duration of the Parliament.
