The use of PE pipes is still quite common,and there are several stages during the hot melt docking process in the production of PE pipes.The hot melt reactions in these stages are different,but they are also interrelated.Next,let's learn about the several stages of PE pipe hot melt docking:
1.Preheating stage of the product:
This stage is used to establish the fusion ring for butt welding,which starts heating the pipe after the welding preparation work is completed.
2.Heating stage:
The heating stage of PE pipes is an important step.

3.Next is the stage of removing the heating plate:
This stage is also used to remove the heating plate for better contact with the surface to be welded,so the shorter the time during this process,the better.
4.Welding stage:
This process is the process of wrapping and combining the molecular chains of the molten material on the welding end face of the PE pipe under pressure.
5.Cooling stage:
After the completion of PE pipe welding,it is the cooling stage,which is to avoid external interference.
So,when PE pipe manufacturers perform hot melt docking on PE pipes,it is also important to take relevant protective measures in addition to correct operation.If you want to learn more about PE pipe products,you can consult us.
