PE Pipe Water Supply Pipe / HDPE Mine Gas Pipe DN20-1000 Steel Wire Frame HDPE Pipepipe Fittings
HDPE Pipe Water Supply Pipe / HDPE Mine Gas Pipe DN20-1000 Steel Wire Frame HDPE Pipepipe Fittings
Description:
HDPE is a good pipeline, not only should have good economy, but also should have a series of advantages such as stable and reliable interface, material impact resistance, crack resistance, aging resistance, corrosion resistance, etc. Compared with traditional pipes, HDPE pipeline system has The following series of advantages:
⑴Reliable connection: The polyethylene pipe system is connected by electrothermal fusion;
⑵ good low temperature impact resistance;
(3) Good stress cracking resistance;
⑷Good chemical corrosion resistance;
⑸Aging resistance, long service life;
⑹ Good wear resistance;
⑺Good flexibility;
⑻ Small resistance to water flow;
⑼Easy to carry.

Specifications and connection methods of HDPE pipes
The diameter of HDPE pipes ranges from DN32 to DN1000, and is divided into 26 grades.
The pressure level is between 0.6Mpa ~ 1.6Mpa, with a total of 5 levels.
The connection method of PE pipe usually adopts two methods: electric hot melt connection and hot melt butt joint. According to the size of the pipe, it can be divided into: when DN≤63, injection molding hot melt socket connection is used; when DN≥75, hot melt connection is used. Butt connection or electrofusion socket connection; flange or thread connection when connecting with different materials.
In terms of pipeline repair methods, there are expansion pipe construction method and lining HDPE method.
The advantages of PE water supply pipeline in application
1. It is easy to form a closed anti-seepage system by butt welding and electrofusion welding.
2. Light weight and easy to install and handle;
3. Strong wear resistance and excellent hydraulic performance, no need for outer protection in buried pipelines.
4. Chemical corrosion resistance, internal, external and microbial corrosion resistance, strong corrosion resistance, and healthy.
5. Good environmental adaptability and frost resistance.
6. Long service life, with a service life of more than almost 50 years;
