PPR the hot melt temperature is about 260℃ (the deviation can be 10℃), and the heating time varies according to different specifications and wall thickness. Generally, the hot melt time of D20 * 2.8 S3.2 pipe is 3~5S, the heating time should not be too long, and shrinkage will occur, so it is OK to ensure that the outer wall of the pipe is melted. Hot melt machines on the market have digital display temperature and no digital display temperature. They are easy to use and can adjust the temperature. Generally, the heating temperature without digital display temperature is much higher.
