■ Good hygiene performance: no heavy metal salt stabilizer is added during PE pipe processing, the material is non-toxic, no scaling layer, no bacteria breeding, and it solves the secondary pollution of urban drinking water.
■ Excellent corrosion resistance: Except for a few strong oxidants, it can withstand the erosion of a variety of chemical media; there is no electrochemical corrosion.
■ Long service life: PE pipes can be used safely for more than long-term durability according to standards under rated temperature and pressure conditions.
■ Good impact resistance: PE pipe has good toughness and high impact resistance, and heavy objects directly press through the pipe, which will not cause the pipe to rupture.
■ Reliable connection performance: The strength of the PE pipe hot-melt or electric-melt interface is higher than that of the pipe body, and the joint will not be disconnected due to soil movement or live load.
■ Good construction performance: the pipeline is light in weight, the welding process is simple, the construction is convenient, and the overall project cost is low.
Pipe connection:
■ Electrothermal welding: use a special electric welding machine to connect the straight pipe and the straight pipe, and the straight pipe and the pipe fittings. Generally used for tubes below 160mm.
■ Hot melt butt connection: use dedicated butt welder pipes to connect, generally used for pipes above 160mm.
■ Steel-plastic connection: It can be connected by flanges, threaded threads and other methods.
■ To facilitate construction and ensure construction quality, corresponding tools should be prepared.
