Advantages of ppr tubeSource： Date:2013-7-7
Advantages of PP-R-In addition to the general plastic pipe's light weight, corrosion resistance, non-scaling, long service life, etc., it also has the following main features:
1, non-toxic and hygienic. The raw material molecules of PP-R are only carbon and hydrogen. There are no harmful and toxic elements. It is sanitary and reliable. It is not only used in hot and cold water pipes, but also used 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 PP-R tube is 131.5 ° C. The maximum working temperature can reach 95 ° C, which can meet the requirements of hot water systems in building water supply and drainage specifications.
4. Long service life. PP-R pipe has a working life of more than 50 years under the working temperature of 70 ℃ and working pressure (PN) of 1.0MPa (provided that the pipe must be S3.2 and S2.5 series); at room temperature (20 ℃) The service life can reach more than 100 years.
5. Easy installation and reliable connection. PP-R has good welding performance. Pipes and fittings can be connected by hot-melt and electric welding, which is convenient to install and reliable in joints. The strength of the connected parts is greater than the strength of the pipe itself.
6. Materials can be recycled. PP-R waste is cleaned and crushed and recycled for pipe and pipe production. The amount of recycled materials does not exceed 10% of the total amount, which does not affect product quality.
