在供水管道中使用球墨铸铁管的好处:
The advantages of using ductile iron pipes in water supply pipes are:
1.由于球墨铸铁管采用柔性接头,施工操作较为方便,可提高施工效率、改善施工条件、降低施工成本,而且接口大部分采用胶圈连接,操作简便,能缩短工期,降低施工造价。

1. because the flexible joint of the ductile cast iron pipe is used, the construction operation is more convenient, it can improve the construction efficiency, improve the construction conditions and reduce the construction cost, and the interface is connected mostly by the rubber ring. The operation is simple, the construction time can be shortened and the construction cost can be reduced.

2.球墨铸铁管具有承受供水压力高,能抵抗外部荷载和适应地质条件的变化,管材具有强度高、韧性好、耐腐蚀、柔性接口安装方便、抗震性强、劳动强度低等优点,可适用于地质差的地段和横穿公路,不需另外加工钢管,再加上耐腐蚀性强,能适用于沿海和盐碱地带。目前在地下管线工程中广泛应用。大型管道安装工程更能体现其安装便捷,劳动强度低的优势。
The 2. ductile cast iron pipe has the advantages of high pressure of water supply, resistance to external load and adaptation to geological conditions. The pipe has the advantages of high strength, good toughness, corrosion resistance, easy installation of flexible interface, strong earthquake resistance, low labor intensity and so on. It can be applied to geological poor areas and cross roads, without additional processing steel pipes. It has strong corrosion resistance and can be applied to coastal and saline alkali areas. At present, it is widely used in underground pipeline engineering. The installation of large pipelines can better reflect the advantages of convenient installation and low labor intensity.
3.球墨铸铁管密封性能好,不易渗漏,可减少管网漏失率和降低管网日常维护费用。
3. ductile iron pipe has good sealing performance and is not easy to leak. It can reduce leakage rate and reduce daily maintenance cost of pipe network.
