The importance of hydropower installation is self-evident. Today we mainly talk about the waterway project. The installation of sewer pipes in waterway engineering is more important, and the sewer pipes are the most prone to water leakage. Not only the quality of the sewer pipe is better, but also the size of the water pipe is also particular. Let’s learn about the size of the sewer pipe together.
Downpipe standard size
1. The drainage branch pipe connected to the washbasin, washbasin, bathtub, and sanitary basin has a pipe diameter of dn32 (the diameter of the sewer pipe is 32 mm), and dn40 (the diameter of the sewer pipe is 40 mm) can be used for larger specifications.
2. The diameter of the drainage branch pipe connected to the urinal and the urinal is dn50 (the diameter of the sewer pipe is 50 mm), and dn75 (the diameter of the sewer pipe is 75 mm).
3. The diameter of the drainage pipe connected to the toilet is dn110 (the diameter of the sewer pipe is 110mm).
4. The diameter of the drainage horizontal pipe and drainage vertical pipe connected to the toilet shall not be less than dn110 (the diameter of the sewer pipe is 110mm).
5. The diameter of the drainage pipe of the urinal or the drainage pipe connecting more than 3 urinals shall not be less than dn75 (the diameter of the sewer pipe is 75 mm).
6. The diameter of the drainage standpipe in the residence shall not be less than dn75 (the diameter of the sewer pipe is 75mm)
Sewer pipe installation tips
Installing the basin sewer pipe is a very simple matter. The installation of the basin sewer pipe is generally the last step after the basin drainer and the basin are installed and fixed, and it is also the last step in the entire basin installation process. Specific steps are as follows:
1、确保面盆和面盆排水器已经安装好；
2、将购买的面盆排水管拆开包装；
3、面盆排水管一端专门连接面盆排水管，拧下该端的塑料头；
4、将拧下的塑料头拧到面盆沥水器上；
5、将面盆排水管套在面盆排水器上，用预先拧在排水器上的塑料头拧紧；
6、放掉水，测试是否漏水。如果出现渗漏，可先将生料带缠在排水管与下水管的连接处，然后再进行第五步。
The above are the size standards and installation skills of the sewer pipes introduced to you. In order to prevent your own sewer pipes from being a safety hazard, let’s learn more.
