How to install the water supply pipe and the steps

Water supply pipes involve daily water delivery and water supply issues, and their installation is very important. The installation steps of water supply pipes can be roughly divided into installation preparation, prefabrication, installation of main pipes, risers, branch pipes, pipeline pressure testing and flushing. part, which will be described in detail below.

1. Installation preparation: Check whether there are any problems with the coordinates and height of the water supply pipe, the size of the hole and the specification of the pipe sleeve meet the requirements, and the laying position of the extension pipeline should be cleaned up.

2. Prefabrication: measure the actual size of the installation according to the markings made in advance, and then carry out prefabrication work such as pipe breaking, threading, fitting of pipe fittings, and straightening of pipe sections.

3. Main pipe installation: The main pipe of the water supply pipe refers to the pipe section from the main valve or water meter to the water supply riser. When installing, start from the main entrance, arrange the pipes in sequence by number and tighten them in sequence with a pipe wrench. After the installation is completed, make sure that the installation direction of the main pipe is correct and not bent, and a temporary wire plug should be added to the nozzle.

4. Riser installation: The water supply riser is a pipeline that needs to be installed vertically. It needs to be installed in a unified way and installed in sequence. After installation, the hemp head should be removed, and the exposed thread should be coated with anti-rust paint.

5. Branch pipe installation: It is necessary to reasonably determine the position of the clamp according to the direction of the branch pipe, and then install the branch pipes in sequence from the opening of the riser, then level and align, and install the temporary wire plug.

6. Pipeline pressure test: Hydraulic test should be carried out on the installed pipeline: connect the temporary pipeline of the pressure pump, put clean air when filling with water, and pressurize after the water is full, if there is no water leakage or seepage phenomenon is qualified.

7. Pipeline flushing: flushing should be performed before acceptance. When flushing the water supply pipe, it can be flushed with the maximum flow rate of the design of the water pipe, so that the water quality can meet the specified cleanliness requirements.

The above are the specific steps for the installation of water pipes, I hope the above content can help you.
