摘要
结合城市给水管网管材的选择，介绍了钢管在给水工程中的发展状况，综述大口径输水管线利用钢管承插式柔性接口，实现钢管给水管线成品化生产的相关工艺技术。
The development status of steel pipe for water supply engineering are introduced, conbined with the pipe selection for urban water distribution network. The relevent process which produces finished steel pipe for water supply with socket flexible joint in large diameter water transmission pipeline are reviewed
