Before the installation
Inside of the cooling water pipe was seriously blockaded caused by corrosion. Therefore, the clogged cooling water pipe for the welding robot stopped the whole production line often.
9 months after the installation
The corrosion was reduced to magnetite
and clogs of the cooling water pipe disappeared. So, the whole production line did not have to be stopped.
Color
The rust before the installation of PIPETECTOR was red color.
The rust taken 9 months after the installation of PIPETECTOR became and formed
magnetite film covering the inner pipe.
Analysis of Mass Magnetite
According to the analysis done by Tokyo University of Science, before the installation of
PIPETECTOR, the ratio of magnetite as 4% while corrosion was 96%, but 9 months after
the installation, magnetite became 43.6%. It proves that corrosion was reduced to
magnetite which became film and protected the pipe.
Installation Summary
| Method of Water Supply | Circulation water method |

Economical Profit by the Installation of Pipetector
The following economical profit was found after the installation of
Pipetector, the corrosion which clogged the cooling water pipe was reduced to
magnetite, and decreased the clog.
- Increase of production because of the increased cooling effect and no stop of
operation by clogging the pipe. - Decrease of cost because of the unnecessary of stopping operation and decreased
maintenance fee. - Decrease of running cost because of the unnecessary of the use of Anti-corrosive
chemical.
