What are the characteristics of PE water supply pipes?

The flexibility of PE water supply pipes also enables them to effectively resist underground movement and end loads. On the surface, plastic buried pipes are inferior to cement pipes and metal pipes in terms of strength and rigidity, but from a practical application perspective, plastic buried pipes are flexible pipes. When storing and transporting PE water supply pipes, they should be bundled with non-metallic ropes, not metal ones, and the painted ends should be sealed to prevent foreign matter from entering them. During its transportation, it must not be thrown or collided to avoid damaging the pipe.

PE pipes have certain comprehensive advantages in urban water supply, such as safety, sanitation, and convenient construction, and have become an ideal pipe for urban water supply. Replacement of cement pipes, galvanized pipes, iron pipes, etc. to transform old pipes can be done without extensive excavation. The unique electrofusion connection, hot-melt butt joint, and hot-melt socket connection technology make the interface strong and consistent with the pipe body, ensuring the safety and reliability of the interface. PE water supply pipes have excellent stability and anti-aging properties. Under normal operating temperature and pressure conditions, the service life is guaranteed to be more than 50 years.

When properly designed and laid, PE water supply pipes bear the load together with the surrounding soil. The pressure relaxation characteristics of PE water supply pipes can effectively consume stress through deformation. Its actual axial stress level is far lower than the theoretical calculation value, and its elongation at break is generally greater than 500%.

When PE water supply pipes are used, some pitting will be found on the surface of the pipe, so they are worried that the quality of the pipe with pitting is not good. Because the raw materials in the machine head and barrel of the equipment undergo oxidation and deterioration after being heated for a long time, the PE pipe on the basis becomes some larger pits or pits. During installation, apply glass glue evenly on the interlayer of all connecting pipe mouths in the axial direction. It must not be missed or too thick. After applying the adhesive, find the right place immediately before placing the pipe. Make it vertical and squeeze it hard for two seconds. It takes three minutes to make the interface firm.
