Precautions for installation and construction of PE hollow winding pipePrecautions for installation and construction of PE hollow winding pipe
1. The pipe mouth should be aligned, and the pipe connection process should be careful, and avoid contamination of the interface. It is not allowed to move the pipeline within 30 minutes after the pipeline is connected.
2. The heating time of the pipeline and shrinkage belt should be moderate, otherwise the connection will not be dense or burnt.
3. The shrinkage belt model should correspond to the pipe diameter. If the belt model is wrong, it will affect the quality of the interface.
4. The heating of PE hollow winding pipe and shrinking belt should be uniform, roast from the middle to both sides, and must not be roasted from both sides to the middle to avoid air bubbles.
