給水管의 環境腐蝕特性 및 壽命豫測에 관한 硏究

Abstract

The quality of the supply water which is supplied to consumer is not the thing of water after filtrating but the thing of water from faucet through pipe. As a result, heavy metals and microorganism, that is the major materials, which cause the distrust of the supply water is generated by supply process. Especially, the heavy metal is generated by the corrosion of supply water pipe. Besides, rupture by corrosion of pipe becomes the factor of supply water's pollution in waterworks and the factor of pollution of the soil and environment in drain pipe. Therefore, this research examined the weight reduction and electric potential measure, corrosion surface to measure the corrosion degree of piping materials after testing the corrosion of service pipes(Stainless steel pipe, Copper pipe, Galvanized steel pipe) which is generally used at the moment in various corrosion environments(subterranean water, supply water, 3.5% NaCl, 3.5% HNO3, 1% H2SO4) and let me show basic design data about problem occurrence such as leakage water, rust water, inside and outside corrosion from this.
