Installation Purpose and Result

British Broadcasting Corporation in London is the national broadcasting company in the United Kingdom built in 1953. One of the BBC buildings where the television programs being made for the White City area in London have had major problem of corrosion in the iron pipework of the condensate water pipework system involving the cooling towers, so NMR Pipetector was adopted by the TV station. For the protection of the condensate water pipework system from internal corrosion in the Main Block Building and in the Stage 5 Building, four units of NMR Pipetector PT-250DS were installed onto the 10 inches diameter independent condensate water pipework systems.

32 days after the installation, Fe content in water considerably decreased from 5.53 mg/l to 0.048 mg/l in the Main Block Building and 3.8 mg/l to 0.063 mg/l in the Stage 5 Building. 57 days after the installation, the Fe content stayed at low of 0.06 mg/l in the Main Block Building and 0.008 mg/l in the Stage 5 Building.

This indicates that new forming of corrosion (FeO(OH)) inside the pipework was immediately terminated and the existing corrosion was reduced to magnetite (Fe3O4) which does not dissolve into water. NMR Pipetector protects inner pipe from any internal corrosion until the life duration of the TV station.
