Since chemical inhibitors are not allowed to use to protect water pipes from being damaged by corrosion because it is no good for health. Corrosion colored water was found in many rooms, so PIPETECTOR, which does not need the construction work to stop water supplying, was installed in order to stop corrosion and prolong the water supply pipes for more than 40 years.
6 weeks after the installation of Pipetector, water examination was done on sample water which was 500ml of water taken in the morning.
Fe content in water decreased from 2.0mg/l (before the installation of Pipetector) to 0.27mg/l, and discolored degree went down from 30 degrees to 5 degrees, and the corrosion colored water completely stopped.
It proves that corrosion inside of the water pipes stopped, started decreasing its volume and being reduced to magnetite which covers inner water pipe wall and protects the pipe.
While the cost of replacement of water pipe would be some hundred millions of US dollars, PIPETECTOR costs less than 1/10 of the conventional changing pipes methods. Moreover, PIPETECTOR is highly evaluated because it is unnecessary to stop supplying water for the installation of Pipetector.
