球墨铸铁管有哪些安装步骤

作者: -1    发布时间: 2018-08-01    次浏览
1、选址,从土壤质量、附近管线等角度来选定球墨管的安装路线,并形成施工图纸,特别要注意的是要避免一些腐蚀性的不安全安装路线。
1. Site selection. Choose the installation route of nodular ink pipe from the perspectives of soil quality and nearby pipelines, and form construction drawings. In particular, some corrosive and unsafe installation routes should be avoided.

2、铺管,球墨铸铁管铺管过程中需要用到挖掘机、吊装机等大型设备,同时根据经验10米长度的球墨管适合安排2至3工人就行配合铺管。胶圈要放正在承口槽内,并用手压实。
2. For laying pipes, large equipment such as excavator and hoisting machine should be used in the process of laying ductile iron pipes. Meanwhile, according to experience, 10-meter ductile iron pipes are suitable for arranging 2-3 workers to lay pipes. The rubber ring should be placed in the socket groove and pressed by hand.



3、确定管道距离,这个环节主要的岁过长的管子就行截断,并按照施工角度把插口端加工成坡口形状,以利应用。
3. Determine the pipe distance, and the main over-aged pipe in this link will be cut off, and the end of the socket will be processed into a groove shape according to the construction Angle, so as to facilitate the application.

4、管身测量,通过对球墨铸铁管管身的测量来确定安装弧度、空缺、转交等形成的直线空距、转角空距、以达到稳固避免位移。
4. Pipe body measurement. Through the measurement of ductile iron pipe body, the straight line spacing and corner spacing formed by the installation radian, vacancy and transfer are determined to stabilize and avoid displacement.

5、定位标线。定位标线的目的是为了达到,定管、动管轴心线存在与一条轴距一样的直线上,这个环节是为了保证安装的质量和速度,避免管道胶圈脱落影响质量和进度。
5. Positioning mark. The purpose of positioning the mark line is to achieve that the axis line of the fixed pipe and the moving pipe exists on the same line as an axis distance. This link is to ensure the quality and speed of installation and avoid the loss of the rubber ring of the pipe to affect the quality and progress.

球墨铸铁管适合安装的工程项目主要取决与它的一个重要要素:屈服强度(σp0.2)的值,当DN40~1000北京天臻钰钢铁科技有限公司建议产品安装在城市供水管网中。
The project of ductile iron pipe fitting installation mainly depends on the value of one of its important elements: the yield strength (jing p0.2), when DN40 ~ 1000 Beijing tianzhenyu steel technology co., ltd. recommends that the product be installed in the urban water supply pipe network.
