What is the welding temperature of PE pipe?

As a plastic pipe widely used in water supply and drainage, gas transportation and other fields, the welding quality of PE pipe is directly related to the safety and service life of the entire pipeline system. As a key parameter in the welding process, welding temperature is one of the core elements to ensure that the interface is firm and leak-free.

Under normal circumstances, the welding temperature of PE pipe will vary according to its raw material grade and specific product characteristics. For common PE pipes of PE80 and PE100 grades, the recommended welding temperature is generally between 200 ° C and 230 ° C. In actual operation, this temperature range needs to be strictly controlled. If the temperature is too high, it may lead to carbonization and degradation of the pipe welding surface, which affects the welding strength and sealing performance; if the temperature is too low, it may cause insufficient welding and the interface is prone to leakage.

In addition to welding temperature, heating time, butt pressure and other parameters are equally important, they together constitute a complete welding process system. As a professional pipe manufacturer, AD Pipe always emphasizes the importance of standardized construction. It is recommended that when welding AD PE pipe, be sure to refer to the product manual or relevant technical specifications, combined with the pipe diameter, wall thickness and other factors to set reasonable welding parameters. At the same time, to use the standard of hot melt welding equipment, and to ensure that the equipment is running normally, heating plate clean.

Before welding, the pipe port should be cleaned and shaped to remove the oxide layer and impurities, to ensure that the butt surface is flat. During the welding process, the operator needs to have professional skills, pay close attention to temperature changes and welding process, to ensure the quality of welding. After the welding is completed, it needs to be cooled according to the regulations to avoid external interference. After the interface is completely cooled and solidified, the follow-up construction can be carried out.

In short, accurately grasping the welding temperature and related process requirements of PE pipes is the basis for ensuring the long-term stable operation of the pipeline system. Selecting PE pipe products with reliable quality like AD pipes and strictly following the scientific welding process can effectively avoid engineering hazards caused by improper welding and provide solid pipeline protection for various fluid transportation projects.
