1. Long service life: Under rated temperature and pressure conditions, PE pipes can be safely used for more than 50 years. 　

　
2. Good construction performance: the pipeline is light, the welding process is simple, the construction is convenient, and the comprehensive cost of the project is low.

3. Superior corrosion resistance: except for a few strong oxidants, it can resist the corrosion of various chemical media; No electrochemical corrosion.

four Good sanitary performance: PE pipes are processed without adding heavy metal salt stabilizer, and the material is harmless, without scaling layer, and without breeding bacteria, which solves the secondary pollution of urban drinking water. 　

5. Good impact resistance: PE pipe has good toughness and high impact strength. Heavy objects directly press the pipe and will not cause pipe rupture.

6. Reliable connection performance: the strength of PE pipe hot-melt or electrofusion interface is higher than the pipe body, and the joint will not be disconnected due to soil movement or live load 。
