南阳配套一标输水管线工程PCCP管线全程18.95 km,管道内径2.20 m,管道采用双胶圈密封,抗渗性能好,水头损失小,管道安装完成后,需进行静水压试验。试验的目的在于对PCCP压力输水管道工程中的管道、管件、阀件及镇墩等附属建筑物设计、施工、安装阶段的质量进行综合检验。通过管道静水压试验,验证管道及各附属建筑物在正常运行工况下的管道强度及水封严密性。
The PCCP pipeline of Nanyang supporting a standard water conveyance pipeline project is 18.95 km in length and the pipe diameter is 2.20 m. The pipe is sealed with double aprons and has good impermeability and head loss. After the pipe installation is completed, hydrostatic pressure test is required. The purpose of the test is to conduct a comprehensive inspection of the quality of the design, construction and installation phases of the affiliated buildings such as pipes, fittings, valves and piers in the PCCP pressure water pipeline project. Through the pipeline hydrostatic test to verify the pipeline and its subsidiary buildings under normal operating conditions, pipeline strength and tight seal.
