1. Strong Corrosion Resistance. The wear resistance of HDPE pipe is stronger than ordinary steel pipe, it is about 4 times than normal steel.
2. No-scale, small frictional resistance and low energy consumption.
3. Light weight, the weight of HDPE pipe is only about 1/5 of the ordinary steel pipe. And HDPE pipe can be cut and welded at will. It is convenient to remove, install and repair.
