Features of PP-R tube:
In addition to the characteristics of light weight, corrosion resistance, non-fouling and long service life of PP-R pipe, PP-R pipe also has the following main features:
1. Non-toxic and hygienic. PP-R's raw material molecules are only carbon and hydrogen, and there are no harmful and toxic elements. It is hygienic and reliable. It is not only used for hot and cold water pipes, but also for pure drinking water systems.
2, insulation and energy saving. The thermal conductivity of the PP-R tube is 0.21 w/mk, which is only 1/200 of the steel pipe.
3. Better heat resistance. The Vicat softening point of the PP-R tube was 131.5 °C. The maximum working temperature can reach 95 °C, which can meet the requirements of the hot water system in the building water supply and drainage regulations.
4, long service life. PP-R tube has a service life of more than 50 years under the working temperature of 70 ° C and working pressure (PN) of 1.OMPa; the service life of normal temperature (20 ° C) can reach more than 100 years.
5, easy to install, reliable connection. PP-R has good welding performance. Pipes and fittings can be connected by hot melt and electric fusion. It is easy to install and joints. The strength of the joint is greater than the strength of the pipe itself.
6, the material can be recycled. After being cleaned and crushed, PP-R waste is recycled and used in the production of pipes and fittings. The amount of recycled materials does not exceed 10% of the total amount, and does not affect the quality of the product.
