本工程共有碳钢管道7581m,碳钢管道焊接是本工程施工的重点,直接影响施工质量的好坏,所以我们应高度重视,保证工程的施工质量。 Carbon steel piping in this project is 7581 meter long, so welding work for carbon steel piping is one of the most important work in the construction. We will pay high attention on this, to guarantee quality of this project.
镀锌钢管明敷设 Open Lay of Galvanized Steel Pipe 本工程明敷设钢管均采用了镀锌钢管明敷设工艺。 All open-lay steel pipes in the project adopt the open-lay technology of galvanized steel pipe.
项目名称: 本工程涉及三个变电站,分别是现有的220/35kV A472变电站、现有的35/10kV B301S变电站以及新建的35/10kV C581变电站,工作内容为三个变电站之间和从三个变电站接至MV用户的电力电缆、控制电缆、接地电缆敷设所需电缆沟的开挖工程。The project involves three substations, namely the existing 220/35kV A472 substation, the existing 35/10kV B301S the 35/10kV C581 substation and a new substation. This is the power, control and grounding cable trench excavation project among three substations and for MV users connected to the three substations.

内容简介 1、镀锌钢管明敷设 Open Lay of Galvanized Steel Pipe 本工程明敷设钢管均采用了镀锌钢管明敷设工艺。 All open-lay steel pipes in the project adopt the open-lay technology of galvanized steel pipe. (1)工艺流程 Technological process: (2)可上人的吊顶内以及不封闭式竖井通道内的配管为明配管,其管路走向及支架固定均应按明配管要求施工。 The distributing pipe in suspended ceilings that can be entered into and shaft passages that are not closed is open. Both its pipeline direction and support fixture should construct according to requirements of open distributing pipes. (3)按设计要求用冷煨法把管子煨出所需的弯度,20mm以下管径的管子用手板煨管器,25mm以上管径用液压煨管器(或专用煨管器),煨弯处凹扁度应符合规范规定。 Use the simmering method to simmer pipes with a necessary bend according to design requirements. Pipes that the pipe diameter is less than 20mm may adopt a palm simmer pipe machine. Pipes that the pipe diameter is more than 25mm may use a hydraulic simmer pipe machine (or special simmer pipe machine). The concavity at simmering bends should accord with specifications and regulations.
