PE water supply water pipe has a series of advantages, such as high toughness, corrosion resistance, anti-cracking, stable interface, light and easy construction, etc., and is widely used in urban water supply. In addition to the traditional excavation method of construction, can also use non-excavation technology for construction.
HDPE water supply product features:
Good hygiene: PE tube processing does not add heavy metal salt stabilizer, material non-toxic, no fouling layer, no bacteria, a good solution to the secondary pollution of urban drinking water.
Excellent corrosion resistance: with the exception of a few strong oxidants, it can withstand the erosion of a variety of chemical media;
Long-term service life: AT RATED TEMPERATURE AND PRESSURE, PE PIPES CAN BE SAFELY USED FOR MORE THAN 50 YEARS.
Better impact resistance: PE tube toughness, high impact strength, heavy material directly through the pipe, will not cause the pipeline to break.
Reliable connection performance: PE tube hot melt or electromelt interface strength is higher than the pipe body, seams will not be disconnected due to soil movement or live load.
Good construction performance: light pipe quality, simple welding process, convenient construction, low overall construction cost.
Connection of the pipeline:
Electrothermal melting: A special electrothermal welding machine is used to connect the straight tube with the straight tube, the straight tube and the fitting. Generally used for tubes below 160mm.
Hot-melt docking connection: the use of special docking welding machine pipe connection, generally used for more than 160mm tube.
Steel-plastic connection: can be used flange, thread edgtorch and other methods to connect.
In order to facilitate construction and ensure the quality of construction, the corresponding tools should also be prepared.
Such as: rotary cutter a cutting pipe; rotary scraper - scrape off the surface of the pipe oxidation skin; climbing wall scraper - scraping the skin of the surface of the large-calibre pipe; gas-cutting tool - to achieve gas-cut field operation.
Connection steps:
1. Clamping and cleaning ports
2. Adjust and level the port
3. Port to straight
4. Pressure fusion
5. Unpressurized cooling
Application s:

Agricultural irrigation pipes.
Post and telecommunications lines, power wire protection casings.
Mine mortar pipeline.
Post and telecommunications lines, power wire protection casings.
Advantages of HDPE water supply
1. High strength, good resistance to environmental stress cracking, good anti-creep performance;
2. Toughness, flexibility, adaptability to uneven foundations and dislocations, and to withstand harsh environments such as earthquakes and typhoons;
3. Good weather resistance (including UV resistance) and long-term thermal stability;
4. Corrosion resistance, no need to do anti-corrosion treatment, long service life;
5. The inner wall is smooth, the water flow resistance is small, the circulation capacity is large, saving the construction cost;
6. Good wear resistance, anti-wear;
7. Good anti-low temperature impact performance, can be used safely in the temperature range of -20 to 40 degrees C, winter construction is not affected;
