Pipe Features
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.
Welding Procedure
1) Fix the welded pipe and fittings on the docking machine, use fixture according to the pipe size, and planed the end surface with milling cutter, so that the docking end surface is smooth, smooth, clean and vertical.
2) Adjust the height of pipes and fittings, so that the welded pipe and fittings end-face completely coincide, and connect the heating plate.
3) When the heating plate is heated to the rated temperature automatically, the welded pipes and fittings will be merged to make the end face heated. After the heating time is reached, the pipes and fittings will be separated from the heating plate, and then the two heating ends will be merged and docked to form a uniform flange at the merging place, which will be cooled.
