PE material can withstand the characteristics of most industrial chemicals. Compared with ordinary steel pipes, PE pipe has a certain degree of flexibility, and the construction is also very simple, and it is not used for anti-corrosion treatment, saving a lot of working procedures. So what regulations should be paid attention to when installing PE pipes? Let's lead everyone to understand it together.

1. Before connecting the pipes, the pipe fittings, pipes and ancillary equipment should be checked correctly according to the design requirements, and the appearance should be checked at the construction site to see if they meet the requirements before they can be used. During the inspection, the main items to be inspected include external surface quality, pressure rating, matching quality, consistency of materials, etc.

2. For pipes connected by welding, use pipe fittings and pipe materials of the same brand. For similar performance, it must be tested first, and then it can be continued after being qualified.

3. The corresponding special heating tools must be used according to different interface forms, and open flames can not be used to heat pipe fittings and pipes.

4. The pipe fittings and pipes should be placed on the construction site for a certain period of time before they are connected, so that the temperature of the pipe fittings and the pipes can be kept consistent.

5. The end of the pipe must be kept clean when the pipe is connected, and the pipe mouth must be temporarily plugged after each time the work is finished to prevent debris from entering the pipe and affecting the use.

6. When connecting in cold weather (below -5 degrees) and windy conditions, certain protective measures or adjustments to the connection process must be taken to protect the nozzle from wind, rain and sand, and prevent damage. Damage to the pipe.

7. After the pipes are correctly connected, the visual inspection should be carried out carefully. If there is any unqualified situation, it should be reworked immediately.

The above are several installation regulations for PE pipes. In the installation of pipes, each item is very important. In order to ensure the smooth installation of the pipeline, the installer needs to be more careful, so that the pipeline can be put into use smoothly, and through the correct management and use, the service life of the pipeline can be prolonged.
