1.Compared with the traditional gravity drainage system, the siphon drainage system without slope;less material; the construction are greatly reduced; reduction of pipe diameter; save installation space;pipe has self-cleaning function;design, construction is simple and quick;widely applicable to various purposes buildings.

2. Smooth inner wall, and does not change with time, small frictional resistance,save energy, the pressure loss about 30% smaller than the steel tube,can choose smaller than steel pipe diameter. Health performance is good, no additives, no possibility of pollution of drinking water, ISO standard grading polyethylene material level 0 (the lowest), no mildew material, compared with some other commonly used plastic material of polyethylene is much mildew resistance, use for a long time also not fouling.

3. Polyethylene pipe can be welded joint with pipe become an organic whole, without the possibility of joint leakage, water saving, reducing operation cost and maintenance cost examination, pipe can be manufactured in any length, but the flexible layout, saving fittings.

4. PE pipe installation available welding or fused to form a completely closed seepage control system.

5. Light, easy to install, handling, connection, construction is convenient and reliable.

6. Has good flexibility, small can winding pipe, pipe winding along the ditch, can resist formation geological change, can be used as liner repairing old pipeline.

7. Good low temperature resistance, corrosion resistance, long life, buried pipeline within to 40 °C and 40 °C.
