Features of PPR pipe

PP-R pipe has the following main characteristics in addition to the general plastic pipe's light weight, corrosion resistance, no scaling and long service life.

1. Non-toxic and hygienic. The raw material molecules of PP-R are only carbon and hydrogen elements, and there are no harmful and toxic elements. It is hygienic and reliable. It is not only used in hot and cold water pipes, but also in pure drinking water systems.

2. Heat preservation and energy saving. The thermal conductivity of PP-R pipe is 0.21w/mk, which is only 1/200 of that of steel pipe.

3. Good heat resistance. The Vicat softening point of the PP-R pipe is 131.5 °C, and the maximum working temperature can reach 95 °C, which can meet the use requirements of the hot water system in the building water supply and drainage code.

4. Long service life. The service life of PP-R pipe can reach more than 50 years under the condition of working temperature of 70℃ and working pressure of 1.0MPa; the service life of PP-R pipe can reach more than 100 years at normal temperature (20℃).

5. Easy installation and reliable connection. PP-R has good welding performance. The pipes and fittings can be connected by hot melt and electrofusion, which is easy to install and reliable. The strength of the connecting part is greater than that of the pipe body.

6. Materials can be recycled. The PP-R waste is cleaned and crushed and then recycled for the production of pipes and fittings. The amount of recycled material does not exceed 10% of the total, which does not affect product quality.
