供水管道是城市供水系统中最重要设施,其投资约占供水系统总投资的70%,在供水管道安装完成之后,水压试验是检查供水管道施工质量合格与否的一个重要标准。一般我们对水压试验的要求有两点:(1)它要能够正确反映管道渗漏情况;(2)试压不出问题,也不能因为试压而使接口遭受损伤反而影响了工程质量,或返工重试造成浪费,更不能出人身安全事故。影响供水管道试压成功的因素很多:如管
The water supply pipeline is the most important facility in the urban water supply system. Its investment accounts for about 70% of the total investment of the water supply system. After the installation of the water supply pipeline is completed, the hydrostatic pressure test is an important standard for checking the quality of the construction of the water supply pipeline. Generally, we have two requirements for the hydrostatic test: (1) it must be able to correctly reflect the leak condition of the pipeline; (2) there is no problem with pressure test, nor can the damage to the interface due to pressure testing affect the quality of the project. Or rework to retry causing waste, but not a personal safety accident. There are many factors that affect the success of water supply pipeline pressure test:
