Application Notes For HDPE Water Supply Pipe

Dec. 05, 2018

1. It should be used as a sheltering measure when it is laid out in the open air and there is sunlight.

2. Buried HDPE Water Supply Pipe, DN ≤ 110 pipeline installation in the summer can be slightly serpentine laying, DN ≥ 110 pipeline because of sufficient soil resistance, can resist thermal stress, no need to reserve pipe length; winter, both There is no need to reserve the length of the pipe.

3. When the HDPE pipeline is installed, if the operation space is too small (such as: pipeline wells, construction inside the ceiling, etc.), the fused connection method should be adopted.

4. When the hot-melt socket is connected, the heating temperature should not be too high or too long, and the temperature should be controlled at 210±10°C. Otherwise, the molten material extruded in the fitting will be excessive, and the inner diameter of the water will be reduced. Or the pipe interface should be clean, otherwise it will cause the socket to be leaked; at the same time, it is necessary to control the angle and direction of the pipe to avoid rework.

5. When the hot-melt butt connection is required, the voltage is required to be between 200 and 220V. If the voltage is too high, the temperature of the heating plate will be too high. If the voltage is too low, the docking machine will not work normally; the interface should be aligned when docking, otherwise The joint area is not enough, the weld strength is not enough, and the curling is not correct; when the heating plate is heated, the pipe joint is not cleaned, or the heating plate has oil, sand and other impurities, which will cause the interface to be leaked and drained; heating time To be controlled, the heating time is short, and the heat absorption time of the pipe is not enough, which will cause the welding bead to be too small, and the heating time is too long, which will cause the welding bead to be too large, and it may form a virtual welding.
