摘　　要：实验室试验和现场应用结果表明,少量使用缓蚀剂就可对铜管有较好的缓蚀作用。分析认为现场应用中存在着缓蚀剂浓度过大或过小以及对缓蚀剂的评价方法不正确等问题。应根据拟使用的水质和钢管条件,通过试验,正确选择缓蚀剂和缓蚀剂使用浓度。The results of tests in laboratory and on-site use indicate that,to use a small amount of corrosion inhibitors has a better corrosion-inhibition effect on copper tubes.The analysis shows that,concentration of inhibitors being too high or too low,and incor-rect appraisal method etc.problems exist in the on-site application.The corrosion inhibitors should be selected and used correctly through testing based upon the water quality and copper tube conditions.
