Official Scientific Report of NMR PIPETECTOR Installation
Anti-Corrosion Equipment, Mandarin Oriental Hyde Park London
Appearance of the building
Installation Purpose and Result
The domestic hot water system which supplies hot water for the bathrooms and kitchens throughout the hotel had a major problem with internal corrosion in its steel galvanised pipework. To eliminate internal corrosion and single cell bacteria including the prevention of any electrolysis between dissimilar metals such as steel and copper, two units of NMR Pipetector PT-75DS were installed onto two main domestic hot water flow pipe headers coming from the two main boilers.
4 weeks after the installation of NMR Pipetectors, Fe content in water considerably decreased from 13.35 mg/l before the installation of NMR Pipetector to 0.0043 mg/l after the installation, and eventually decreased to 0.0335 mg/l 8 weeks after the installation on the domestic hot water pipework systems.
It means that new forming of corrosion (FeO(OH)) inside the pipe works were immediately terminated and the existing corrosion were reduced to magnetite (Fe3O4) which does not dissolve into water. NMR Pipetector will continue to provide the hotel the full protection against internal corrosion and single cell bacteria in excess of forty years.
