Because the pipe has good characteristics, so in many fields of product transportation will be used in the product, we will know that not the performance and characteristics of the product is very good, there will be no problems when using it, we need to follow the correct operation steps to use in order to play the corresponding use effect. In addition to following the correct instructions, it is important to understand the following installation specifications:

1. Before connecting PE pipes, pipes, fittings and pipe accessories should be checked, according to the design requirements, and the appearance and quality should be checked before construction, and they can only be used if they meet the standard requirements.

2. Generally, pipes, fittings and pipe accessories are hot-melt connected or mechanically connected, and manual hot-melt socket connection cannot be used when the nominal outer diameter of the pipeline is greater than or equal to 110mm. For polyethylene pipes and fittings, threaded connections cannot be used.

3. If the polyethylene pipe belongs to different SDR pressure level series, it cannot be connected by hot melt butt, and when the pipe is connected with metal pipe or metal pipe accessories, it should be connected by flange or steel-plastic transition joint.

4. Special connection tools should be used when connecting the pipes, and it is strictly forbidden to heat the PE pipes with open flames.

5. pipes and pipes should be connected with the same grade and the same pressure level, and different grades of pipes and pipes should be tested before they are connected. The connection can only be made after it is determined that the quality can be guaranteed.

6. When steel sprayed plastic or ductile iron transition pipe fittings are used, the pressure level of the transition pipe fittings cannot be lower than the nominal pressure of the pipe.

7. When carrying out the hot melt connection operation of PE pipes, if it is in a cold climate or windy condition, there should be protective measures.

8. Special cutting tools should be used for pipe cutting, and the cutting section is required to be flat, smooth, burr-free, and perpendicular to the pipe axis.

Through the above introduction, we can see that in order to give full play to the corresponding use effect of PE pipes, in addition to following the correct installation operation, we should also pay more attention to the above installation specifications, so that there will be no problems when the pipes are used. During the period of use, the pipes should also be regularly inspected and the anti-corrosion work of the pipes should be done, so that the pipes will not be affected by some external factors.
