1) Good hygienic performance: PE pipe processing without adding heavy metal salt stabilizer, non-toxic material, no scaling layer, no bacteria, a good solution to the secondary pollution of urban drinking water. 2) Good corrosion resistance: Except for a few strong oxidants, it can resist the erosion of various chemical media; no electrochemical corrosion. 3) Long service life: Under rated temperature and pressure conditions, PE pipeline can be used safely for more than 50 years. 4) Better impact resistance: PE pipe has good toughness, high impact strength, heavy objects directly pressed through the pipeline, will not lead to pipeline rupture. 5) Reliable connection performance: PE pipe hot-melt or electric-melt interface strength is higher than the pipe body, the joint will not be broken due to soil movement or live load. 6) Good construction performance: light pipeline, simple welding process, convenient construction, low comprehensive cost of the project. Pipeline Connection: 1) Electric-thermal weldability: The straight pipe and straight pipe, straight pipe and pipe fittings are connected by special electric-thermal welder. Usually used for pipes under 160mm. 2) Hot-melt butt joint: Use special butt welder pipe connection, generally used for more than 160mm pipes. 3) Steel-plastic connection: flange, thread and other methods can be used to connect. Application: Hesu Pipe Industry's high-performance high-density polyethylene water pressure pipes are suitable for municipal and industrial transmission systems for potable water, sewer, drain, mining, irrigation, and reclaimed water.
