摘　　要：用交流阻抗等电化学方法分析了新旧铜管的耐蚀性,通过试验、分析,认为偏高的水温,偏低的流速是铜管腐蚀的主要原因,加入一定量BTA能显著提高铜管耐蚀性。Corrosion resistant properties of both the new copper tube and old copper tube are analyzed by galvano - chemistry methods. After tests and analyses, it is believed that higher water temperatures and lower flow velocity are the main cause of copper piping corrosion and by adding certain amount of BTA the corrosion - resistant property can be greatly raised.
