谈长距离大管道严密性水压试验

Talking about the tightness water pressure experiment of long distance and large cross-section pipes

结合城市热网管道的建设,探讨了长距离大管道安装后怎样进行水压试验的问题,阐述了理论计算过程和严密性水压试验方法,总结了在太原集中供热二电工程14 km管网主干线严密性试验的成功经验。

Combined with the construction of urban heating pipeline after installing long distance and large cross-section pipes how to carry out water pressure experiment is studied. The theory calculation methods and tightness water pressure experiment methods are clarified. Finally combined with certain heating project successful experiences are summarized.
