1. The pipes should be clean
Before welding, check all ppr pipelines, and confirm whether the outer wall of the ppr pipeline is smooth and smooth. If there is oil, dust, etc. on the outer wall, wipe the outer wall. In addition, it is also necessary to investigate whether the inner wall of the ppr pipe is clean and dirty. When the ppr pipe is used later, it will cause pollution to the water quality. In addition, the inner wall of the ppr pipe must be kept dry. If there are water droplets on the inner wall, air bubbles will appear during welding, and even lead to various problems during welding.
2. The incision should be flat
When cutting ppr pipe, it should be ensured that the incision is clean, flat and free of burrs. If the incision is deformed, the ppr pipe pipeline and the pipeline are not in a straight line during welding, the welded ppr pipe will be deformed, and the life of the joint will easily be shortened.
3. The temperature of the hot melt machine should be enough
When using a fuser, it is necessary to preheat the temperature of the fuser to ensure good welding of the ppr line.
4. The hot melt time should be appropriate
During welding, sufficient time is required, and the welding time is short, and the phenomenon of incomplete melting of the ppr pipe, temporary welding, and weak welding will occur, and water leakage is likely to occur in the later use.
