수돗물에서 주철관과 아연도강관의 부식특성 및 영향인자에 관한 연구

Abstract

The experiment was investigated for studying the ion generation and corrosion rates that occured in the pipe system. Application of water treatment device named “SB” in water-pipe systems produces the electromotive force from galvanic reaction. This electromotive force is named as galvanic electronic. Above reaction decreases leakage, scale, rust, slime such as bacteria inside of water-pipe. Thus, SB can be used as the pipe protection device in the water distribution system. A study uses the loop type water circulation system connected with iron pipe and galvanized steel pipe with/without SB. Results showed that the Fe concentrations in the water pipe system without SB connection was about two times higher than these of the water pipe system with SB connection. The corrosion rates of the pipe system installed SB were about 17~28% less than these of the pipe systems with out SB. Therefore the control of pipe rust by SB was proved by this study.
