The application of HDPE water supply pipeline should be paid attention to

- Jan 02, 2018-

1. Outdoor outdoor laying, where there is sunlight, suggest to do shelter.

2. Embedded HDPE water supply pipeline, the pipeline with a DN of less than 110 will be slightly snaked over the summer, and the pipeline with a DN greater than 110 will be resistant to thermal stress due to sufficient soil resistance, so it will not need to be reserved. In winter, no reserve is required.

3. When the HDPE pipe is installed, if the operating space is too small (such as: pipe well, ceiling construction, etc.), electric fuse connection shall be adopted.

4, the heating temperature of hot melt socket connection, not too high, too long, the best temperature control in the 210 plus or minus 10 ℃, otherwise will cause the parts in extrusion of magma is overmuch, reducing water inside diameter; The pipe fittings or pipe fittings should be cleaned at the time of insertion, or it will cause the socket to leak off. At the same time, it is necessary to control the Angle and direction of the pipe fitting and avoid causing rework.

5. When the thermal fusion connection is connected, the voltage is required to be between 200 and 220V. If the voltage is too high, it will cause the heating plate to be too hot and the voltage too low. The interface should be aligned with the interface, otherwise it will result in insufficient joint area, insufficient welding strength, and the unrolled edge. When heating plate heating, the pipe joints are not cleaned, or the heating plate has oil, sediment and other impurities, which can cause the interface to leak out. The heating time should be controlled well, the heating time is short, the heat time of the tube is not enough, it will cause the edge of the welding seam to be too small, and the heating time will be too long.
