    • PROBLEM TO BE SOLVED: To provide a water non-suspending ST short pipe and a method for laying a distributing pipe with which the number of times of water suspension is reduced by half, a water suspension range is reduced or water suspension can be avoided through simple work while reducing the number of components.SOLUTION: A water non-suspending ST short pipe 1 used for a construction of laying a distributing pipe comprises piping connecting parts 3, 4 which are formed in both ends of a pipe body 2, a gate valve attaching/detaching part 5 to which a gate valve for shutting off a fluid flowing in the pipe body 2 is attached, and a water cut-off valve attaching/detaching part 6 for mounting a water cut-off valve which enables branching to temporary piping. One of the piping connecting parts has an inner diameter larger than that of the pipe body and the other piping connecting part has an inner diameter in the same shape as that of the pipe body. Furthermore, the piping connecting parts in both the ends have an inner diameter in the same shape as that of the pipe body. Moreover, the piping connecting parts in both the ends have the inner diameter larger than that of the pipe body.
    • 要解决的问题:为了提供水不悬浮的ST短管和用于铺设水悬浮液的次数减少一半的分配管的方法,减少水悬浮范围或水悬浮可以 通过简单的工作避免,同时减少组件的数量。 解决方案:用于铺设分配管的结构的非水悬浮ST短管1包括形成在管体2的两端的管道连接部3,4,闸阀安装/分离部5 安装用于切断在管体2中流动的流体的闸阀的闸阀,以及用于安装能够分支到临时管道的截水阀的截水阀安装/拆卸部6。 其中一个管道连接部分的内径大于管体的内径,另一个管道连接部分具有与管体相同形状的内径。 此外,两端的配管连接部的内径与管体的内径相同。 此外,两端的配管连接部的内径大于管体的内径。 版权所有(C)2013,JPO&INPIT
