Hot melt connection PE100 SDR11 DN630 HDPE Pipe For Municipal water supply system:
The pressure grade is between 0.4mpa and 1.6mpa, with 5 grades.The best suitable melting temperature is from 190℃ to 240 ℃,the pipe (or pipes) will have a good contact with both parts of the melt. After cooling for a short while, the two parts can be firmly integrated.Therefore, the connection mode of PE pipe is different from that of u-pvc pipe. Generally, the two methods are electric hot melt connection and hot melt butt joint. Connect with different materials using flange or thread connection.
The specifications of PE pipes for water supply are as following for reference:
The features of PE pipes are as following:
1.High toughness and good seismic performance;
2. The connection is reliable;
3. Low density, light weight, easy to handle and install;
4. Can resist a variety of chemical media corrosion;
5. Excellent hydraulic performance, the wear resistance coefficient is only 0.009;
6. Long service life, up to 50 years;
7. Good hygiene and environmental performance;
8. Better resistance to slow crack growth (SCG) and rapid crack propagation (RCP).
9.Environmental health: new polyethylene as raw material, no toxic additives, no scaling, no bacteria breeding.
10.Durable: Corrosion resistance: good material stability, effective corrosion resistance Impact resistance: good toughness, high impact resistance Low temperature resistance: can be used at -60℃ High wear resistance: wear resistance is better than metal pipes Long service life: more than 50 years.
11.Reduce cost and increase efficiency: Light weight: easy to carry and save engineering costs Easy to install: using socket and docking method.
Application of PE water supply pipe:
HDPE pipes can be used for general purpose pressure water conveyors as well as for drinking water conveyors.There are municipal buried water supply, construction to (drainage) water, farmland irrigation, waterscape projects. In the water supply pipeline project, PE water supply pipe will eventually replace UPVC pipe.
