摘　　要：随着国家大型调水管网项目不断增多,PCCP管、钢管和球墨铸铁管均在全国各地得到广泛应用,特别是大口径球墨铸铁管引起众多施工单位和业主的关注。就球墨铸铁管与PCCP管、钢管的接口、外防腐、施工便捷性、管道后期维护等几个方面进行了系统的比较和分析,认为球墨铸铁管在大口径输水管道应用中具有一定的优势。With the continuous increase of national large-scale water diversion projects, PCCP pipes, steel pipes and ductile iron pipes are widely used throughout the country, especially the large di- ameter ductile iron pipes have attracted the attention of many construction units and owners. Ductile iron pipe was compared with PCCP pipe and steel pipe in terms of joint, external corrosion, construction con- venience, pipe post-maintenance, and the analysis indicated that ductile iron pipe had a certain advan- tage in application of large diameter water diversion pipes.
