HDPE pipes are non-toxic and tasteless, which meets the standards to transport drinking water and is suitable for urban and rural water supply pipeline systems. The butt fusion process makes the pipeline connection secure to eliminate water leakage, which ensures the reliability of the water supply system. The inner wall of HDPE pipe is smooth and the water flow resistance is small, which can effectively reduce water loss and ensure water quality. At the same time, HDPE pipes have strong weather and UV resistance, which is suitable for long-term use.
